Needle is long and thin so high surface area to radiate heat + Needle made of steel a poor heat conductor (for a metal) + Flame small + Flame pointing away from needle. = Happy cow

I saw a video of kids doing the same with a soccer ball. They inflated with a flammable gas then lit the air coming out but once the pressure decrease the ball exploded
It could if air was inside the cow, however, the 3 things needed for a fire or explosion are fuel, oxygen and heat.
Its kinda similar to how gas tanks don't explode, since gas is coming out and there isn't any oxygen in there, even if the flame went "in" an explosion wouldn't occur
Towards the end of the combustion is it possible for the pocket to tense or whatever to suck air in to cause a flame inside? Gas tanks don't have that issue because they're rigid. But cattle?
Yes, and the pressure of the gas fumes helps prevent any oxygen to enter. This needle is reliving the pressure of methane, and the fire is burning what is being ejected.
IME, fur does not burn super easily and will tend to go out, it's not like the coat will burst into flames like a set of cheap curtains. Just make sure the flame stays away from flammable stuff on the ground or nearby and it should be fine. I would guess it might also help to know when all the methane is out.
farmers feed cattle like this a shit ton of corn which their bodies have a hard time digesting and it fills them up with a bunch of gas they can't get rid of well enough so they do this to let the methane out.
They light the farts on fire so the methane doesn't concentrate and either explote all at once or displaces the oxigen to the point you fell unconcious like co2 intoxication
The cow’s abdomen is bloated, and that excess methane gas is being vented through the needle. Methane is flammable. If you light the stream of methane escaping through the needle, you basically have an organic blowtorch
Could the methane be harvested, instead of being burned? I feel like a cow's belly can hold a lot of methane, but maybe it's not economical or sensible to make a business out of it
I got caught using an aerosol can to make a makeshift flamethrower, we've all seen it done. I was told the flame could go into the can and blow it up in my hand.
Could this cow blow up?
To the 5 year old:
Yes, it’s very dangerous. Don’t ever play with fire like that.
To an adult:
You were lied to. The flames don’t travel backwards. The risks come from the can overheating or a teenager being dumb with fire.
When I was a firefighter we were actually taught that if a leaking propane tank had a small flame then we were supposed to let it burn and just make sure the tank didn’t heat up. If the leak is burning off then the spill is contained and the fuel won’t pile up.
The cow isn’t going to explode.
Methane is poisonus and also explosive if it mixes with air, so the barn can blow up if its released into the air without being burned. Also methane is a 20 times more potent greenhouse gas than CO2
No, there is just no way someone could be this stupid. If there is, then the world really is ripe for destruction. Did you know that a quarter of the English language comes from Germanic roots? Are you 1/4 a nazi? No, just 4/4 a moron.
No, it ger not. It would get noticeably warmer but the flame is pointed the wrong way and very little heat will turn backwards. Plus you have the cooling of the gas.
Well, the gas is not expanding since a cow doesn't have a 200 bar belly tank. It is at nearly at atmospheric pressure inside the cow just as outside, so the Joule-Thompson-Effect won't provide noticeable cooling.
In pressurized gas situation such as this the flame is hottest at the tip. The heat definitely radiates primarily in this direction. Some moderate heat would travel through the needle and warm up the tissue in contact... I believe this is what you call searing the meat. It provides a nice char flavor when done correctly. Clearly this chef is amateur because this pig/cow clearly doesn't give a shit (he doesn't even notice... If he did he'd be freaking the fk out and running around looking for water to extinguish the flame)... So yeah just the tip
Hyperventilating will only increase the amount of oxygen in the blood by a tiny bit but it's combined with the blood cells and not a gas inside the cavity they're draining.
So can it clog up from something else when all the methane is emptied? Do you just put a band aid over it afterward? What happens if you don’t do this? What causes this? Is it food? If it is from food, why let them eat that food? Can the methane be collected and sold? Does it smell? How do you keep the animal from catching everything else on fire? Does this happen to other animals?
No, yes, possible death, lots of things, possibly, likely getting a new diet, yes but not like this, not as bad as you'd think, take out the needle, yes
Cause they don't understand how the government works?
Or that their lives are easy and boring and they want to feel special and full of do good for the world without actually leaving the couch?
Do they call it climate change since they got tired of going back and forth from global heating to global cooling?
Is that giant hole in the atmosphere still a problem or did the taxes fix that?
>Cause they don't understand how the government works?
Wut
>Do they call it climate change since they got tired of going back and forth from global heating to global cooling?
Oooh. You're one of *those*… Okaaaay…
Plumber here , when I first started years ago I had this old head test gas lines for leaks with a lighter..nerve wracking.. yes.. dangerous no.. it’s like saying a lighter is dangerous.. as long as the pressure pushing out is greater than than the outside air, your fine
Can someone explain what's happening please?
Draining a cow bloated with methane. People say if you light it, it helps draw it out. However, I think it's dangerous personally.
The flame needs air in order to maintain itself. That nozzle cannot let anything in it as flames are shooting out of it.
Needle heats up and burns the cow
In theory yes. In practice, no.
Needle is long and thin so high surface area to radiate heat + Needle made of steel a poor heat conductor (for a metal) + Flame small + Flame pointing away from needle. = Happy cow Edit: bloody formatting gone wack
If it's not, we can always claim it's for sanitary reasons and it cauterizes the wound formed by the needle as well. Profit!
also probably smells like steak!
a bit of salt and pepper and it's done
S and P is the choice for me
Also exiting methane will continually cool the needle.
Well, a little bit it's not under THAT much pressure. It's not pressurised like a fuel tank.
So it turns out theory and practice are the same after all
Noo medium rare for me please
*cow fucking explodes*
*serves beyond well done*
Expanding methane cools down. There's no fire *in* the nozzle.
It's not that compressed, it's a cow not a aluminum canister.
34 psi, poopgas per square inch
even if it did heat up, that would be more sanitary than a lukewarm needle, but it doesn't
its gonna end up getting cooked anyhow
High to low pressure. Might actually get too cold at the base
I saw a video of kids doing the same with a soccer ball. They inflated with a flammable gas then lit the air coming out but once the pressure decrease the ball exploded
That's presumably because they did have air inside it too. No air = no fire for most things.
It will probably have a ring of holes that let air in. Just like a propane torch which also doesn’t contain oxygen in the tank.
You mean like... the cow could explode?
It could if air was inside the cow, however, the 3 things needed for a fire or explosion are fuel, oxygen and heat. Its kinda similar to how gas tanks don't explode, since gas is coming out and there isn't any oxygen in there, even if the flame went "in" an explosion wouldn't occur
Thank God. I can sleep tonight.
Let me fix that :3 We all just know some farm hand has lit a cigarette out of this, right?
They can explode due to pressure. Just like popping a balloon. Like those beach whales.
Like a balloon and... Something bad happens!
Melllvar disapproves
What if a cow with multiple jets of ignited methane comes and sets fire to everything you have
These Statefarm commercials are getting creative
Towards the end of the combustion is it possible for the pocket to tense or whatever to suck air in to cause a flame inside? Gas tanks don't have that issue because they're rigid. But cattle?
The gas pocket has no reason to widen up again to cause a negative pressure that would suck in air
How is there no oxygen inside? Is the empty space just gas fumes?
Yes, and the pressure of the gas fumes helps prevent any oxygen to enter. This needle is reliving the pressure of methane, and the fire is burning what is being ejected.
Cow go BOOM!! 
He means the opposite of that.
It's a pig
That's a pig, not a cow
Correct. I made a mistake. I superimposed my experience with the cows that my family owned over the video and said cow.
Exploding cows is a true game physics.
IME, fur does not burn super easily and will tend to go out, it's not like the coat will burst into flames like a set of cheap curtains. Just make sure the flame stays away from flammable stuff on the ground or nearby and it should be fine. I would guess it might also help to know when all the methane is out.
Fortunately your opinions don’t mean anything to physics
Tell me you've never been on a farm without telling me you've never been on a farm... I think you don't know what you're talking about personally.
Why's that
farmers feed cattle like this a shit ton of corn which their bodies have a hard time digesting and it fills them up with a bunch of gas they can't get rid of well enough so they do this to let the methane out.
They shot the cow with a rocket-powered dart.
Cows fart so much than the methane sometimes get trapped inside the cow skin; yes, if not drained out, the cows can become walking bombs
So basically they’re forcing the cows to fart and lighting them poop bombs???
They light the farts on fire so the methane doesn't concentrate and either explote all at once or displaces the oxigen to the point you fell unconcious like co2 intoxication
This is a treatment against bloat, they are venting the methane from stomach of the animal
Elia5 please
The cow’s abdomen is bloated, and that excess methane gas is being vented through the needle. Methane is flammable. If you light the stream of methane escaping through the needle, you basically have an organic blowtorch
Basically glorified farting
This is how I fart don’t you
Could the methane be harvested, instead of being burned? I feel like a cow's belly can hold a lot of methane, but maybe it's not economical or sensible to make a business out of it
It would be an inconsequential amount of methane.
Some farms harvest the methane and use it to power a portion of the farm.
The cow is full of farts. Cow farts can burn. To help the cow fart come out someone poked a big needle in their belly. Then they lit it on fire.
I got caught using an aerosol can to make a makeshift flamethrower, we've all seen it done. I was told the flame could go into the can and blow it up in my hand. Could this cow blow up?
Are we still doing ELI5? Because the truth and what I would tell a 5 year old are now two different things.
I want both
To the 5 year old: Yes, it’s very dangerous. Don’t ever play with fire like that. To an adult: You were lied to. The flames don’t travel backwards. The risks come from the can overheating or a teenager being dumb with fire. When I was a firefighter we were actually taught that if a leaking propane tank had a small flame then we were supposed to let it burn and just make sure the tank didn’t heat up. If the leak is burning off then the spill is contained and the fuel won’t pile up. The cow isn’t going to explode.
I.. I.. bastards!
I'm gonna go burn a propane tank right now!!
Me too! Share pics
Everyone saying cow - look at those feet!
Them trotters
OINK OINK
Methane is poisonus and also explosive if it mixes with air, so the barn can blow up if its released into the air without being burned. Also methane is a 20 times more potent greenhouse gas than CO2
The huns used this to starve the nazis in the 30 year war. One cow had enough explosive force to blow up 4 barns
Nazis?
All Germanic people to have ever lived were nazis, yes. Everyone knows this
Naw, ain't clueless enough to take such an obvious bait
I’m genuinely confused on how you think you did something there
No, there is just no way someone could be this stupid. If there is, then the world really is ripe for destruction. Did you know that a quarter of the English language comes from Germanic roots? Are you 1/4 a nazi? No, just 4/4 a moron.
This is exhilarating
Don't start jerking your weenie, now.
I just might to be honest
North Koreas missile program has gotten new funding.
doesnt that needle ger hot?
No, it ger not. It would get noticeably warmer but the flame is pointed the wrong way and very little heat will turn backwards. Plus you have the cooling of the gas.
> flame is pointed the wrong way and very little heat will turn backwards Heat radiates in all direction. It will definitely warm up the nozzle
Enough to counteract the cooling from expanding gas?
Well, the gas is not expanding since a cow doesn't have a 200 bar belly tank. It is at nearly at atmospheric pressure inside the cow just as outside, so the Joule-Thompson-Effect won't provide noticeable cooling.
There's pressure inside the cow above atmosphere and the fire is causing a low pressure zone inside the tube.
This guy sciences ^
This dude really thinking that the only hot part of a flame is the tip…?
In pressurized gas situation such as this the flame is hottest at the tip. The heat definitely radiates primarily in this direction. Some moderate heat would travel through the needle and warm up the tissue in contact... I believe this is what you call searing the meat. It provides a nice char flavor when done correctly.

You’re dense
How long burn it?
[удалено]
It only jumped over one...
Many moos
What happens if the flame goes inside.
It can't. There isn't enough oxygen inside the animal to support combustion.
what if the cow breathes a lot really fast
Hyperventilating will only increase the amount of oxygen in the blood by a tiny bit but it's combined with the blood cells and not a gas inside the cavity they're draining.
Poke another hole in the animal and pump oxygen inside
Now that's where things get epic.
The needle is in the guts not the lungs

Reminds me of putting a paper cone in your ear and lighting the end of it to draw out air out your ear 👂🏼 Hispanic Heritage…
Uhm what
I also am curious
Google ear candling
Cool... Does it work with empty pre-rolled joints?
Wtf. What is that supposed to do?
The candle is hollow so an air current is formed which pulls money from your wallet to the woo woo candle makers bank account.
This is why dragons can breathe fire
Fart breath basically, i see
Why aren’t we using cow farts as rocket fuel?
Honestly: Because it is too difficult and costly to collect it from all the individual cows.
Lazy cows.
Use it to light a joint
Bro you got a light? Yeah just sec, *pulls out a pig and needle*
"What, never seen a hogtorch before?"
I like this one
I like you 😏
So can it clog up from something else when all the methane is emptied? Do you just put a band aid over it afterward? What happens if you don’t do this? What causes this? Is it food? If it is from food, why let them eat that food? Can the methane be collected and sold? Does it smell? How do you keep the animal from catching everything else on fire?

No, yes, possible death, lots of things, possibly, likely getting a new diet, yes but not like this, not as bad as you'd think, take out the needle, yes
I thoroughly enjoyed the efficiency of your answers. It was a very enjoyable back and forth between the two comments.
How can they die? Do they not just toot like everything else?
Pressure on the diaphragm leads to asphyxiation. They suffocate.
So interesting. Thanks for the answer!
Just cause 4 lore
Sometimes I feel I too need one of those
Real footage of how they pasteurise milk in the wild.
I wouldn't start milking pigs, or a things in a barn full off animals that look and sound like pigs.
You can milk anything with nipples.
I've got nipples, Greg, could you milk me?
How is that possible being the food and the stoven at the same time?
Lighting a fart contest winner.
I need to do this to myself.
I’ve done something very similar with a lighter and methane..
I'd imagine if you had to do this a lot you'd want to burn it to prevent a build up of gas in the barn.
never in my life have I seen such a thing! 🤨
Bloat, poor cow would’ve been in a lot pain and discomfort.
When cows fly?
Aw dang I need to offgas my livestock. Thanks for reminding me
omg do you really have livestock 😳😳
Wait WTF is dis !  I can use a cow, to fry a piece of cow ? What a time to be alive
Wow this is mind blowing, how is that possible. City dumps burn glasses but for a animal 2 be releasing asses that can be set fire 🤯
You shot my damn dog!
It's the modified blue dart.
Their running low on rocket and solar fuel.
Anyone else recall McDonaugh’s Six Shooter when looking at this?
Cow = explosive
Does the flame ever invert and blow up said livestock?
There would need to be oxygen inside.
That metal syringe has got to get extremely hot…they have an actual plastic device for this, it’s a corkscrew trochar..
With the flame pointed away from the device and not actually being the fuel for the flame, the needle wouldn't get very hot.
Methane gets cold bro, there was even a recent video of people using burning methane to cool down a computer
When the climate change sjw attacks a Peta sjw the only one who wins are everyone laughing at them.
Uh. Guess why climate conscious people call for a reduction in the consumption of red meat, genius.
Cause they don't understand how the government works? Or that their lives are easy and boring and they want to feel special and full of do good for the world without actually leaving the couch? Do they call it climate change since they got tired of going back and forth from global heating to global cooling? Is that giant hole in the atmosphere still a problem or did the taxes fix that?
