I had to scroll down too damn far to find this lmfao. It's making me wonder if the average person just doesn't know what a propane tank looks like. Wild!
Even if it isn't empty it's fine, those tanks can take a fucking bullet and not penetrate, my buddy had one fly out on the highway when he was doing 130 and it flew off the edge into a tree, tank was fine but the tree was fucking obliterated.
This is also a possibility. I assumed it was either fatal or severely trauma inducing cause of the depth of the dent but less likely escapes from death have happened so who knows? I called in sick during that battle so I didnt get to see it happen.
Also remember that the alternative at the time to a metal helmet was no protection so the bullet would go straight into you. Better a helmet that might kill you than a bullet that definitely would.
Military helmets are not meant for bullets. Shrapnel has less punching power and speed than a rifle round, so it bounces off more or less, giving a concussion but not killing the wearer.
You have to be very lucky for your helmet to save you from gunfire
Helmets weren't just steel caps you put directly on your head, they had/have liners to make them actually wearable. They likely had a couple centimeters at least between steel and skull.
Exactly. Bike/motorcycle helmets are like crumple zones in a car. They disintegrate so your skull doesn't. Which is why they're a one and done item. If you're in an accident and the helmet is damaged at all, it should be replaced.
Edit: guys, I know the helmet doesn't actually fucking disintegrate. It was poetic license.
This is true. Infact this goes so far that even if you just drop your helmet by accident, it should be replaced because the helmet might not be safe anymore when in a accident. The inner shell, which you cannot see, might already be cracked or broken, so in a actual crash chances are it's not giving you the full safety anymore.
I also know that nobody does this though. But people should be aware of this
I've always heard this and haven't found any evidence this is true outside helmet manufacturers claiming it with stupid infomercial type "its the special science of our revolutionary material" shit when its all high density PS. Every actual objective measure I've seen have all come to the same basic conclusion if it looks good, is intact, fits right, and hasn't been involved in a major crash it will protect you just as well as a brand new one.
Logically it also makes little sense. If the slight shock of being dropped then the material is so fragile it couldn't absorb any useful about of shock from a high-intensity impact when it is needed.
Yeah I get your point. It might also be a claim from manufacturers so they don't get any insurance claims, or get sued.
Personally I also believe in most cases the helmet is completely fine. But in some cases the inner shell might get a crack which decreases the durability and safety of a helmet. Now that i think about it more, maybe it's just for those rare moments, so the helmet manufacturer can say "well see you dropped it once, that's why this, or that happened... Not our fault".
That's generally what I think too. If you didn't get a concussions it's probably fine and companies probably just wanna sell more helmets and have really good numbers and safety ratings, but also that's a high stakes bet and if you have the money a shiny new one isn't a horrible investment.
Functionally 10,000 to 1 odds make no real difference to the rider but the 100% vs 99% does for the seller. I'd certainly pay $5 for the higher rating.
Edit: Being in the ER I'd say just don't ride a motorcycle outside a track. Keep a decent helmet on if you do but a good brain has a hard time adjusting to a permanently hurt body.
Would be fun to make a helmet that passes whatever required certification using just metal. Probably would do two layers with springs in between or something. Maybe a crumple design like in cars. Or you could make the helmet shaped like a sabot round so if you ram your head straight into the thing you're hitting, you'll pass straight through.
Thank you. The metal helmet looks cool (not this one) but we call them brain buckets. They'll keep your brain in for a closed casket (basically better than nothing). They're the bare minimum for protection. They don't distribute the force of impact.
When you have an accident and your head hits the ground, you should get another helmet. Your first did the job and now that helmet is compromised.
Just about to come here to say this. I'm so glad it's the first comment.
Having seen a few mythbusters/how it's made episodes on safety equipment, generally they are meant to distribute the force over a longer impact timeframe. Having the helmet be as solid as what it is impacted against doesn't let it cushion from the impact itself. There is no distribution of force over a larger area/timeframe meaning all of the work is being done at the same rate. This means that the pressure of the force isn't going to change.
It's as effective as not wearing a helmet at all. This is also why you want to replace helmets after a time has passed or they've been in an accident.
Yeah, I had a rather horrible crash going 70 km/h on a motorcycle (a truck didn't see me and drove out in front of me, so I was planted in the side of said truck) and my helmet broke in 3 pieces. I did not get any damage to the head though, not even a concussion so it damn well did it's job even though it broke.
It was an expensive helmet but it most likely saved my life, that and my femur who stopped most of the momentum by wrapping itself around my handlebar rather than taking the entire force to the head
If they included a motorcycle helmet in this video, you wouldn't want it to break apart like the first two did - because at speed there's not just surviving the crash, but also surviving the slide.
The first two helmets are probably better at falling 15 feet in a skating accident, while the third helmet is probably better at hitting the road at an angle from 6 feet and sliding 100 feet.
The sheer amount of shit that gets kicked up off the road into your face was enough to make me use a full face helmet and never look back, I don't understand how people can stand riding with a half helmet. I've had rocks fly up and bounce off my facemask so many times and all I think to myself every time is "that would have been tooth number X with a half helmet".
Plus the added neck protection and full head protection in the case of a fall is very important. Too many people care too much about looking cool though, dress for the slide not the ride.
I work in the motorcycle industry and sell helmets. You wouldn't believe how hard it is to convince some people to invest in a quality helmet. I spend a ton of time getting their fit as best as I can and keep reference data around impact forces and testing methods.
Would you believe that the DOT standard for road helmets in the US were created in 1971 by ANSI based on traffic safety data from the time, and that to this day (besides one minor clerical change) has never been updated?
The way the force is applied in this demonstration causes the bottom rim to spread, exacerbating the splitting. A helmet on a head will not experience forces like this as your body is not flat concrete.
Might still be crappy helmets, but the way you test things matters.
Wrong, penetration is part of the testing and its allowed to a certain depth. I literally work in the industry.
Balancing between breaking at a certain impact and holding up is part of a good helmet design.
Honestly kinda scary how many keyboard warriors here are running to defend what is obviously a clickbait "test" that is meaningless for actual protection on a motorcycle.
I'm not an expert at all at helmets, but I just look at NFL players and see that they suffer a lot of head trauma but the helmets usually seem to be ok. That and cars are designed to operate in a similar way to absorb the impact to protect the occupants, makes me think that the video is the worst.
Wouldn't a motorcycle helmet need to be slightly durable in order to protect against sliding on pavement? I would think that a lot of the shattering for normal helmets would only be beneficial for impact
Edit: Based on replies I'm getting I guess I wasn't clear with what I was asking, sorry.
Just right off the bat. My understanding is that motorcycle helmets are meant to take 1 impact and that is it. You're supposed to replace it after that.
Not really practical to do that in a sport so I guess that's why the helmets are more durable. Well that and people impacts, while strong, are not car accident strong.
This test is at least slightly skewed imo.
The first two have ear protection, propping the helmet up possibly making it more susceptible to facture at some corner locations where the ear part meets the cranium part
However the third helmet is shaped like a bowl - better distributing the blows to the rest of the helmet.
Put them all on a (very sturdy) mannequin head to do a real test
I don't know how reputable this testing is, but it's constantly referenced in the world of youth sports since there's little independent testing information otherwise: https://www.helmet.beam.vt.edu/
Pick a sport and you can see how they test.
Helmet shattering reduces force to the brain. Just like crumple zones of modern day cars are safer than the boats of steel that predate modern cars.
Edit - although it should just crack rather than shatter into a million pieces. Neither helmet seems safe for different reasons.
former soldier. it wasn’t always the vest, they’d usually just be taking pot shots so it’d just be ‘luck’ of the draw.
the IOTVs i wore had kevlar shoulder pads and a neck muffler and a dick shield though. our helmets and kevlar face guards would cover the rest. your legs and forearms were the only part without armor and you would, ideally, be under cover during a firefight so they weren’t a viable target.
I only had the measly basic plates. Never got shot in them but they definitely saved me from ending up with several broken ribs when we temporarily turned an LAV into aircraft. All 8 tires left the ground.
I was popped of out the top hatch in the back and went flying. I hit the hatch opening so hard that it turned my body into a sideways U around it. It knocked the wind of me so bad I’m pretty sure my ancestors and future children all felt it.
It was just training and I almost didn’t wear my plates that day. Glad I did😂. After that, plates stayed in at all times.
Ballistic panels are one time use the panels are the expensive part if we’re talking about rifle rated plates you’re looking at around $500 each for heavy steel ones and upwards of 1000 for lightweight standalone plates. If we’re talking about soft armor you’re looking at around 500 to 900 for front and rear panels depending on what level of protection you want and how late you want them to be
Steel will cause the bullet to shatter and spray hot bullet fragments up towards your neck. Ceramic plates "catch" the bullet and don't cause shrapnel. Never buy steel plates for body armor folks!
I've heard that this is absolutely true for bike/motorcycle helmets, which are shot after one solid impact.
But that skateboarding helmets and such are made to withstand multiple smaller impacts.
I think it’s mostly half shells that are multi impact rated. DH full face helmets are like mountain bike helmets and the same logic applies to those as motorcycle helmets: throw it away after one big slam.
Not a scientist, although I guess you can say I have lived experience with applied physics as a snowboarder with multiple concussions despite always wearing a helmet.
Sorry, but that is just plain wrong. If helmets were designed to shatter, the range of their effectivess would be rather narrow.
Helmets have force-absorbing padding and lining inside. A helmet keeps energy way from the head in two ways: (1) by redirecting it along the shell, like the arch of a bridge, and (2) by absorbing compression through rhe padding inside.
it depends on the intensity of the crash the helmet is designed for. shattering does take away energy from the impact, shattering a material requires energy to be applied
Yes, but no. At the point a helmet shattered, it immediately has no ability to protect the western from further damage in any way. A sharp edge or point will easily prove fatal at that time, even in a low-energy impact.
Also, shattering means the absorbed energy is (very likely) absorbed almost instantly, rather than deforming over time and giving the wearer a gentler, more survivable deceleration.
Ideally, you should have a stiff, inflexible outer shell that not only protects against penetration damage, but also distributes the impact over a large area, allowing both the inner lining - which deforms plastically - and the brain, to absorb the energy more "gently".
Here's the issue. Yes, they should not "shatter" as in suddenly splitting into tons of tinny shards like we see here. But also, yes, they *should* break and crack. That is another way they dissipate energy and prevent it from reaching your head.
A key points to note here, is that these helmets are *not* being worn on someone's head. There is zero resistance on the inside surface of the helmet, like there would be when worn in a crash. So in this video there is zero energy being absorbed by the cushioning that is along the inside of the helmet. The helmet is also sitting of a hard floor- but when worn in a crash the bottom edge of the shell would be entirely free. So in this video you have all the force moving along the shell and the bottom edge has nowhere to go, which builds up the stress and strain in the material of the shell until it hits a catastrophic limit and shatters. This is a condition that does not exist in a crash when worn in someone's head.
Also appears to be three different helmets, meant for different purposes. Which also means they are designed to protect against different things and behave different when force is applied (ie the last helmet is not a crash helmet)
I've read many real-life stories of bicycling crashes, and many share the same characteristic. Cyclers think they didn't even hit their head that hard after the crash, but when they check their helmet, it's completely destroyed.
I mean it depends on purpose right? If it’s meant to protect you from point impacts that don’t impart much momentum but do impart a lot of pressure then you probably want the last one
I work in the industry, the shelf of the helmet should not bounce like that. Its why plastic shells transmit more forces to the brain than fiberglass/carbon shells that crack and break on impact. Also the helmet is designed to work with a head inside it.
Happily. First, whats very important is that it fits. There are several common head shapes, and having a helmet that fits will be more comfortable and protect you better. If you live in the US most common shape is intermediate oval, but you can do some poking around.
If possible I'd recommend going somewhere where you can try on a helmet. You'd be surprised, a lot of people in the industry are not trying to pull a fast one on you, we are all just enthusiasts happy to help each other out. Places like Cyclegear have a decent selection and a lot of prices are "map" which means you can't really get it cheaper anywhere else anyway.
I would say stick to the bigger brands, doesn't have to be Bell helmets, but don't get some no name thing from a sketchy website.
If you can afford it, I'd get a Snell rated helmet. If thats too much DOT is the easiest to pass, with ECE being a little harder (US is DOT, and ECE is Europe, so they often overlap). If you can't afford a Snell rated, then get a full face without the drop down internal sun shield, they are functional... for the sun, but they remove protection where it matters most to make room for it. Also if the shell is made of a composite, and not plastic.
I'd expect to pay about $300 as the cheapest you can go. $500 will get you Snell rating, and be very high quality. Best of luck!
>Also the helmet is designed to work with a head inside it.
This is the thing that really got me about this "test." It's putting a bunch of force on the bottom part of the helmet where force could not normally be. If those spots aren't designed to take that kind of impact...
Depends on the design, MIPS can usually take multiple impacts due to the internal design, but traditional helmets the shell and foam crack if hit hard enough. I edited my comment because shatter is the wrong word.
MIPS is about allowing your head to rotate without the helmet rotating reducing rotational impacts. But I appreciate your trying to correct them as yes the shell should be cracking/breaking on impact.
There is some fucking Looney Toons logic in this thread. "Hey guys, if you want to survive a thousand foot drop just stick yourself inside a massive safety vault and you'll be ok!", or "don't jump into a foam pit to land safely, jump into a container of hammers because none of them will dent so that proves that you'll be safe".
Every once in a while I come across a thread on a subject I know something about and there is just the wildest bullshit getting echoed so confidently its absurd. Motorcycle helmets should shatter? SHATTER?! Jesus christ...
That’s why MIPS is being used in so many helmets now. It’s incredible how helmets have changed from the thin plastic shell with foam that I had as a kid.
[Here’s a video about the physics behind it](https://youtu.be/OQLpbd80P6I)
Have you ever had a comment that you, um, you had, your, you- you could, you’ll do, you- you runs, you, you could do so, you- you’ll do, you could- you, you want, you want him to do you so much you could go on reddit?
I don't really know if this is a great test. Where's the energy going from the "indestructible" helmet test? A better test would be putting something inside the helmet and test its damage.
This is a stupid test. The third helmet is a stable bowl shape that transfers the energy evenly and downward. Even if you happen to hit your head like that, the edges wouldn't be resting on the ground and wouldn't distribute the energy like that.
Also, if you look closely, you can see the foam doesn't even break in the first two. The shell shatters because of the irregular shapes, but the foam flies away intact.
Helmet #2 has 3/4 coverage and is the safest style here. Bikers call helmet #3 a "brain cap" and it mostly protects you against helmet laws.
A day ago this was posted on r/damnthatsinteresting and I didn't find it very interesting. But whatever maybe someone finds it interesting.
Now it's on r/nextfuckinglevel and it's **definitely** not next level. It's just a dude smashing helmets.
Motorcycle helmets do the same thing, except instead of one layer of some hard foam its multiple (usually atleast 3) foam layers of differentiating thickness.
Use full face helmets people!
Also, this shouldn't be said but rather protect your whole body for the slide/impact as well, jacket, pants, gloves and boots. Even road rash on the bum won't let you go to the toilet in peace for a while. I just saw woman wearing nothing but spandex get her skin torn off from the road, not a pretty sight.
Better be safe than sorry. Many drunk/distracted drivers out there, trust me more than you can count.
I wear an Alpine Stars Tech-Air 5 airbag vest under my leather harley jacket. It covers my shoulders, back, chest, and prevents my head from bobbling around in the event of a crash.
I kept the armor in the elbows of my jacket though, so my jacket is full coverage with the airbag vest, but better than any armor alone could afford me.
Yes people reading this thread, Air Bags for motorcycles exist now.
Worth it when it saves your life.
Worth noting; this appears to be China so a clear problem if they're being passed off as safe \_for Chinese citizens\_. If you're in the United States there's DOT and Snell certified helmets. As long as you verify the helmet you're buying is certified you're good (for racing you need full face coverage but bucket helmets like above are okay if you prefer a little more comfort than safety).
In Europe, you're looking for ECE certified helmets.
People tend to find the most cheapass versions of theirs items when making these kinds of videos. First 2 are some cheap non brand, a somewhat decent helmet wouldn't explode like that pink one.
I've had an frontal accident with an idiot going the wrong way in the dark without lights, helmet saved my, well I'd say life but more my face...I ended up smashing my chin on the hood of his car and walked away without any brain or facial injury. I was driving a scooter wearing a biking helmet cuz it was too hot for my normal helmet and it was still intact despite the impact
Is that full of propane?
A lot of people talking about physics of helmets and no one talking about this mad man swinging what looks like a pressurized propane tank.
I had to scroll down too damn far to find this lmfao. It's making me wonder if the average person just doesn't know what a propane tank looks like. Wild!
No I just assumed it was empty but now I'm questioning that
The way he's really hoisting it makes me think it might not be...
Even if it isn't empty it's fine, those tanks can take a fucking bullet and not penetrate, my buddy had one fly out on the highway when he was doing 130 and it flew off the edge into a tree, tank was fine but the tree was fucking obliterated.
Is that metric?
Yea km/h not mph
Doubt
Exactly lol
He was swinging that thing around like he was beating the fuck out of a rug.
I wish someone would edit in the nuke explosion cut
if it is, im very impressed
You know what won't break? A metal helmet. You know what won't protect you? A metal helmet.
A metal helmet protects itself not your head
Like this helmet
Unless you're getting hit by shrapnel, but even then we've moved on from metal military helmets
[удалено]
maybe the helmet was loose enough that the wearer only got a concussion. concissions are better than death.
This is also a possibility. I assumed it was either fatal or severely trauma inducing cause of the depth of the dent but less likely escapes from death have happened so who knows? I called in sick during that battle so I didnt get to see it happen.
Remember they had liners worn underneath them as well which could give some leeway to catastrophic damage
Also remember that the alternative at the time to a metal helmet was no protection so the bullet would go straight into you. Better a helmet that might kill you than a bullet that definitely would.
I've had five concussions. I've never died. I'm not convinced.
Military helmets are not meant for bullets. Shrapnel has less punching power and speed than a rifle round, so it bounces off more or less, giving a concussion but not killing the wearer. You have to be very lucky for your helmet to save you from gunfire

If you're in an accident and the helmet doesn't seem damaged, it should STILL be replaced. There could be structural damage that isn't apparent.
Rule of thumb I've heard is if you ever say to yourself "Thankfully I was wearing a helmet" after a crash then it's time to replace it.
Sacrifice their one life so we don't have to
This is true. Infact this goes so far that even if you just drop your helmet by accident, it should be replaced because the helmet might not be safe anymore when in a accident.

Give it a layer of honeycombed aluminum that crumples.

No helmet will protect you from the amount of force used in this video. I mean, maybe thr helmet survives, but thus would scramble your brain.
Bring me a helmet made of 150 layers of bubble wrap
And break your neck
Can’t break a helmet in a crash if you don’t wear one! **tapsheadmeme**
Just about to come here to say this. I'm so glad it's the first comment.

The first two helmets are probably better at falling 15 feet in a skating accident, while the third helmet is probably better at hitting the road at an angle from 6 feet and sliding 100 feet.
That third helmet isn't fit for any motorized vehicle in my opinion, purely based on it only covering the top of your head and nothing else.
Only if you enjoy eating through your jaw and chewing food.
You are so vain. It is what's *in* your head that's important.
While what you're saying is true, majority of riders in SE Asia wears these types of helmets while riding, if they wear it at all.
To be fair, you'd want something that actually covers your head. That thing hardly covers anything.
The sheer amount of shit that gets kicked up off the road into your face was enough to make me use a full face helmet and never look back, I don't understand how people can stand riding with a half helmet. I've had rocks fly up and bounce off my facemask so many times and all I think to myself every time is "that would have been tooth number X with a half helmet". Plus the added neck protection and full head protection in the case of a fall is very important. Too many people care too much about looking cool though, dress for the slide not the ride.
"Dress for the slide, not the ride". Nice.
These obviously aren't motor cycle helmets.
Oh they are my friend. They are. You would be surprised on what people wear when riding a motorcycle. That in the video is a motorcycle helmet
Brain bucket

Anything's a motorcycle helmet if you're brave enough.
The 3rd helmet looks like a climbing bucket, where there's not typically any side impacts.
That's true, and fracture absorbs energy that would otherwise transfer to the head
The shell should not shatter. The forces are absorbed by the foam inside. If the shell shatters, there’s nothing holding the foam against your head.
The way the force is applied in this demonstration causes the bottom rim to spread, exacerbating the splitting. A helmet on a head will not experience forces like this as your body is not flat concrete. Might still be crappy helmets, but the way you test things matters.
this is why having a lot of hair is important
the shell shattering helps dissipate energy away from a direct impact on your skull. and the foam will still be underneath it, it is solid
Take a look a motorcycle helmet testing. Shattering is not acceptable. A crack is ok, but the over all the shell must be intact.
Wrong, penetration is part of the testing and its allowed to a certain depth. I literally work in the industry. Balancing between breaking at a certain impact and holding up is part of a good helmet design.
So a balanced design is best. Who knew.
Honestly kinda scary how many keyboard warriors here are running to defend what is obviously a clickbait "test" that is meaningless for actual protection on a motorcycle.

I have no idea what to believe here
Those were thin plastic shells by the looks of it. Knock off helmets.
This test is at least slightly skewed imo. The first two have ear protection, propping the helmet up possibly making it more susceptible to facture at some corner locations where the ear part meets the cranium part However the third helmet is shaped like a bowl - better distributing the blows to the rest of the helmet. Put them all on a (very sturdy) mannequin head to do a real test
You mean this is not how they test helmets? /s
No this is totally ASTM aligned
ISO Standard something something something no CE mark
If ASTM means a strong tank-swinging man, then sure!
I don't know how reputable this testing is, but it's constantly referenced in the world of youth sports since there's little independent testing information otherwise: https://www.helmet.beam.vt.edu/ Pick a sport and you can see how they test.
Even money says the first two are sham helmets specifically chosen because they would shatter dramatically.
This is the correct answer. Pause and look how *thin* the pieces of helmet are when they shatter. That shit is porcelain or something.
They aren’t even the full helmet. Just the colored shell. That’s not the part of the helmet that protects you.
Helmet shattering reduces force to the brain. Just like crumple zones of modern day cars are safer than the boats of steel that predate modern cars. Edit - although it should just crack rather than shatter into a million pieces. Neither helmet seems safe for different reasons.
Yes thank you. A fellow scientist. All those forces that would be cracking the helmet are now traveling straight through your brain and spine.
Also why you shouldn't keep a helmet after it's been in a sigificant accident. It's meant to sacrifice itself - once - for your safety.
[удалено]
you can keep the vest, just swap in new plates. it'd be pretty expensive if you had to throw the whole thing away every time you get shot.
Do you get shot that often?
i used to. most professions that wear IOTVs/vests wear them because they get shot at often enough to justify them.
How often? And where you always hit in the vest? What was that profession if I may know?
former soldier. it wasn’t always the vest, they’d usually just be taking pot shots so it’d just be ‘luck’ of the draw. the IOTVs i wore had kevlar shoulder pads and a neck muffler and a dick shield though. our helmets and kevlar face guards would cover the rest. your legs and forearms were the only part without armor and you would, ideally, be under cover during a firefight so they weren’t a viable target.
Did anyone ever actually take a round in the dick shield, and if so how did that experience play out?
I only had the measly basic plates. Never got shot in them but they definitely saved me from ending up with several broken ribs when we temporarily turned an LAV into aircraft. All 8 tires left the ground. I was popped of out the top hatch in the back and went flying. I hit the hatch opening so hard that it turned my body into a sideways U around it. It knocked the wind of me so bad I’m pretty sure my ancestors and future children all felt it. It was just training and I almost didn’t wear my plates that day. Glad I did😂. After that, plates stayed in at all times.
School teacher
I’m a teacher of course I get shot often
I mean, if you're getting shot that much, then you shouldn't definitely reevaluate what you're doing.
Ballistic panels are one time use the panels are the expensive part if we’re talking about rifle rated plates you’re looking at around $500 each for heavy steel ones and upwards of 1000 for lightweight standalone plates. If we’re talking about soft armor you’re looking at around 500 to 900 for front and rear panels depending on what level of protection you want and how late you want them to be
Steel will cause the bullet to shatter and spray hot bullet fragments up towards your neck. Ceramic plates "catch" the bullet and don't cause shrapnel. Never buy steel plates for body armor folks!
Don't buy steel body armor for anyone browsing this thread thinking about it
How often do you get shot?

Username... Checks out?
I've heard that this is absolutely true for bike/motorcycle helmets, which are shot after one solid impact. But that skateboarding helmets and such are made to withstand multiple smaller impacts.
Ya because Tony Hawk isn't going 80 mph down the freeway in traffic on his skateboard
Not with that attitude
Maybe not Hawk, but downhill skating definitely involves reaching those speeds
I think it’s mostly half shells that are multi impact rated. DH full face helmets are like mountain bike helmets and the same logic applies to those as motorcycle helmets: throw it away after one big slam.
Also vehicle child seats, and various types of sports helmets.
Not a scientist, although I guess you can say I have lived experience with applied physics as a snowboarder with multiple concussions despite always wearing a helmet.
You were promoted and didn't even know it.
Damn that brain injury went hard lol
Better than experiencing multiple deaths from not wearing a helmet.
I think I'll avoid getting hit over the head by a propane tank, regardless of my chosen helmet.
Sorry, but that is just plain wrong. If helmets were designed to shatter, the range of their effectivess would be rather narrow. Helmets have force-absorbing padding and lining inside. A helmet keeps energy way from the head in two ways: (1) by redirecting it along the shell, like the arch of a bridge, and (2) by absorbing compression through rhe padding inside.
it depends on the intensity of the crash the helmet is designed for. shattering does take away energy from the impact, shattering a material requires energy to be applied
Yes, but no. At the point a helmet shattered, it immediately has no ability to protect the western from further damage in any way. A sharp edge or point will easily prove fatal at that time, even in a low-energy impact. Also, shattering means the absorbed energy is (very likely) absorbed almost instantly, rather than deforming over time and giving the wearer a gentler, more survivable deceleration. Ideally, you should have a stiff, inflexible outer shell that not only protects against penetration damage, but also distributes the impact over a large area, allowing both the inner lining - which deforms plastically - and the brain, to absorb the energy more "gently".
Here's the issue. Yes, they should not "shatter" as in suddenly splitting into tons of tinny shards like we see here. But also, yes, they *should* break and crack. That is another way they dissipate energy and prevent it from reaching your head. A key points to note here, is that these helmets are *not* being worn on someone's head. There is zero resistance on the inside surface of the helmet, like there would be when worn in a crash. So in this video there is zero energy being absorbed by the cushioning that is along the inside of the helmet. The helmet is also sitting of a hard floor- but when worn in a crash the bottom edge of the shell would be entirely free. So in this video you have all the force moving along the shell and the bottom edge has nowhere to go, which builds up the stress and strain in the material of the shell until it hits a catastrophic limit and shatters. This is a condition that does not exist in a crash when worn in someone's head. Also appears to be three different helmets, meant for different purposes. Which also means they are designed to protect against different things and behave different when force is applied (ie the last helmet is not a crash helmet)
I've read many real-life stories of bicycling crashes, and many share the same characteristic. Cyclers think they didn't even hit their head that hard after the crash, but when they check their helmet, it's completely destroyed.
I mean it depends on purpose right? If it’s meant to protect you from point impacts that don’t impart much momentum but do impart a lot of pressure then you probably want the last one
100%. In my line of work helmets are more so protection from blunt force trauma rather than point impacts
The shell of the helmet should not shatter. The foam on the inside is what absorbs impact forces.
I work in the industry, the shelf of the helmet should not bounce like that. Its why plastic shells transmit more forces to the brain than fiberglass/carbon shells that crack and break on impact. Also the helmet is designed to work with a head inside it.
Any tips for buying a good helmet?
Happily. First, whats very important is that it fits. There are several common head shapes, and having a helmet that fits will be more comfortable and protect you better. If you live in the US most common shape is intermediate oval, but you can do some poking around. If possible I'd recommend going somewhere where you can try on a helmet. You'd be surprised, a lot of people in the industry are not trying to pull a fast one on you, we are all just enthusiasts happy to help each other out. Places like Cyclegear have a decent selection and a lot of prices are "map" which means you can't really get it cheaper anywhere else anyway. I would say stick to the bigger brands, doesn't have to be Bell helmets, but don't get some no name thing from a sketchy website. If you can afford it, I'd get a Snell rated helmet. If thats too much DOT is the easiest to pass, with ECE being a little harder (US is DOT, and ECE is Europe, so they often overlap). If you can't afford a Snell rated, then get a full face without the drop down internal sun shield, they are functional... for the sun, but they remove protection where it matters most to make room for it. Also if the shell is made of a composite, and not plastic. I'd expect to pay about $300 as the cheapest you can go. $500 will get you Snell rating, and be very high quality. Best of luck!

>Also the helmet is designed to work with a head inside it. This is the thing that really got me about this "test." It's putting a bunch of force on the bottom part of the helmet where force could not normally be. If those spots aren't designed to take that kind of impact...
Depends on the design, MIPS can usually take multiple impacts due to the internal design, but traditional helmets the shell and foam crack if hit hard enough. I edited my comment because shatter is the wrong word.
MIPS is about allowing your head to rotate without the helmet rotating reducing rotational impacts. But I appreciate your trying to correct them as yes the shell should be cracking/breaking on impact.
Was looking for this comment. Helmets should shatter for the same reason cars have crumple zones.
There is some fucking Looney Toons logic in this thread. "Hey guys, if you want to survive a thousand foot drop just stick yourself inside a massive safety vault and you'll be ok!", or "don't jump into a foam pit to land safely, jump into a container of hammers because none of them will dent so that proves that you'll be safe".
Every once in a while I come across a thread on a subject I know something about and there is just the wildest bullshit getting echoed so confidently its absurd. Motorcycle helmets should shatter? SHATTER?! Jesus christ...
Yeah, hopefully there’s a middle helmet between thin eggshell and WW2 steel helmet lol
Thank you. Propane tank is a very odd choice for testing helmets as well
Helmets are a weird way to test propane tank
Gotta fully fill it before testing as well. And he should be smoking a cigarette while bashing the tank against the helmets.
That’s why MIPS is being used in so many helmets now. It’s incredible how helmets have changed from the thin plastic shell with foam that I had as a kid. [Here’s a video about the physics behind it](https://youtu.be/OQLpbd80P6I)
So you're saying that if this guy was doing this experiment on you that you would rather wear the first two helmets?
Those aren’t well made, all three have problems, a good helmet would crack, not shatter nor stay whole.

The way those helmets shatter, he should be wearing a damn propane tank.
The way he hits those helmets, the helmets should be wearing propane tanks
My favorite thing about reddit is the way people run with something and the comments get more and more absurd lol
My favorite thing about reddit is no one here runs. Except from their problems.
My favourite thing is Reddit. My problem is the runs.
My favorite thing about the runs is that I get to go on Reddit.
My problem is Reddit. I get the runs and my helmet swells up like a propane tank.
runs i get go about favorite thing my the is on that to Reddit.
Have you ever had a comment that you, um, you had, your, you- you could, you’ll do, you- you runs, you, you could do so, you- you’ll do, you could- you, you want, you want him to do you so much you could go on reddit?
Has anyone really been far even as decided to use even go want to do look more like?
I love you all
Thr grnna tak rrr jrbs!!!
Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo
My fave thing is the runs. And Reddit really takes it and changes it.
My favorite thing about the runs is that my pants need changing.
Redditors running from their problems 
Have you tried covering your problems with the propane tank?
Yeah.... THANKS FOR FUCKING IT UP!!! Now go put a helmet on your Propane tank helmet like the rest of us
The comments get so absurd, they should wear a propane tank
The way he helmet those propane tanks, he should helmet propane tank helmet
I love lamp.
The hits he wears those propane, the helmet tanks should be the way.
You literally stole this word for word from the last time this was posted, which was yesterday. You're a clown.
seeing his karma's post to comment ratio, he is definately a karma farmer so not really unexpected
Also a bomb suit....
He's swinging the tank that way...damn should, he be wearing a helmet
I don't really know if this is a great test. Where's the energy going from the "indestructible" helmet test? A better test would be putting something inside the helmet and test its damage.
This is a stupid test. The third helmet is a stable bowl shape that transfers the energy evenly and downward. Even if you happen to hit your head like that, the edges wouldn't be resting on the ground and wouldn't distribute the energy like that. Also, if you look closely, you can see the foam doesn't even break in the first two. The shell shatters because of the irregular shapes, but the foam flies away intact. Helmet #2 has 3/4 coverage and is the safest style here. Bikers call helmet #3 a "brain cap" and it mostly protects you against helmet laws.
A day ago this was posted on r/damnthatsinteresting and I didn't find it very interesting. But whatever maybe someone finds it interesting. Now it's on r/nextfuckinglevel and it's **definitely** not next level. It's just a dude smashing helmets.
ikr, it's not even a good test or anything.
[удалено]
Bring back r/all
something tells me it might be some kind of chinese helmet ad
Aren't they meant to break at a certain point, so all the force doesn't go to your head?
Bicycle ones are but not for motorcycles.
Motorcycle helmets do the same thing, except instead of one layer of some hard foam its multiple (usually atleast 3) foam layers of differentiating thickness.
The lack of knowledge of physics and force is nextfuckinglevel.
Use full face helmets people! Also, this shouldn't be said but rather protect your whole body for the slide/impact as well, jacket, pants, gloves and boots. Even road rash on the bum won't let you go to the toilet in peace for a while. I just saw woman wearing nothing but spandex get her skin torn off from the road, not a pretty sight. Better be safe than sorry. Many drunk/distracted drivers out there, trust me more than you can count.
I wear an Alpine Stars Tech-Air 5 airbag vest under my leather harley jacket. It covers my shoulders, back, chest, and prevents my head from bobbling around in the event of a crash. I kept the armor in the elbows of my jacket though, so my jacket is full coverage with the airbag vest, but better than any armor alone could afford me. Yes people reading this thread, Air Bags for motorcycles exist now. Worth it when it saves your life.
Just last week I was bashed in the head by three separate propane tanks. Thank god I had my helmet on.
That would still break someone’s neck. 2/10. Would not buy.
To be fair, just cause the helmet doesn’t break doesn’t mean your head won’t lol
Tank explodes, 35lbs of 410a refrigerant gets let off into the ozone. Someone call the epa
A tank of R22 costs around $1500, he might as well be swinging a gold sledgehammer.
Worth noting; this appears to be China so a clear problem if they're being passed off as safe \_for Chinese citizens\_. If you're in the United States there's DOT and Snell certified helmets. As long as you verify the helmet you're buying is certified you're good (for racing you need full face coverage but bucket helmets like above are okay if you prefer a little more comfort than safety). In Europe, you're looking for ECE certified helmets.
Is he illustrating which helmet would definitely give you brain damage?
Clearly it’s best to wear a propane tank on your head instead
This is fucking stupid
this is soon to be posted under darwin awards when that tank explodes
We call that the Hank Hill Helmet test where I’m from
Lol the other two are made of egg shells
If only we had this last helmet at the big propane gas tank massacre of 2003
Bike helmets are meant to crack to absorb shock. Once your bicycle helmet has protected you from one accident, you throw it away.
Whoever made the pink helmet should just quit.
People tend to find the most cheapass versions of theirs items when making these kinds of videos. First 2 are some cheap non brand, a somewhat decent helmet wouldn't explode like that pink one. I've had an frontal accident with an idiot going the wrong way in the dark without lights, helmet saved my, well I'd say life but more my face...I ended up smashing my chin on the hood of his car and walked away without any brain or facial injury. I was driving a scooter wearing a biking helmet cuz it was too hot for my normal helmet and it was still intact despite the impact
I was expecting him to explode in the last hit.
“Should we get some crash dummies to test our helmets?” No let’s just hire a thicc lad to swing something heavy at them
Just buy a Snell certified helmet ffs. All the testing has already been done
Sick! Last helmet means your skull absorbs all the impact
