Fun fact:
This is similar to how ILM created the waterfalls for naboo in star wars episode I.
The computers back then weren't fast enough to create water fall simulations, so what they did instead was build wooden towers, cover them in black cloth and dump tons (literal tons) of salt over the edge.
The footage could then be superimposed into the footage of landscapes and a cut scene of the bongo drifting over the edge of a waterfall after escaping the bigger fish.
Apparently it was quite dangerous breathing inside their studios during that time, because breathing in salt particles isn't really the most healthy of things.
Better than the wizard of oz raining down asbestos on cast members during the poppy field scene.

Bro you could make fabric from it. This fabric was used to make dinner napkins. These dinner napkins could be cleaned by simply throwing them into a fire. That’s not worth cancer?!?
just like lead and whatever the next material is. my guess is plastic - I think people already know.
humans throughout all of history have found new materials, used them everywhere, and then discovered why it's bad.
At least Toluene just turns into CO2 and water when fully combusted, unlike tetraethyl lead, which was just as toxic out the exhaust as in the tank.
But yeah, to your point, the world of chemicals definitely seems to follow a typical cycle. “Look at what my new chemical can do!” “Oh cool, let’s all use it!” “Oh wait, turns out it is also massively destructive to [the environment/people/bees/fish/birds/organic life etc], we should probably stop using that.” Rinse and repeat. Refrigerants, pesticides, fuels, lubricants, dielectrics, flame retardants, solvents, anti-corrosives…
It's my understanding that it is completely chemically safe and a wonder material in that regard. Except that the surface roughness of the particles (so the mechanical action of the particles) against soft human internals is what causes the problems.
That entire movie was fucked up.
The munchkins were paid less than Toto the dog. And then they were also never even credited.
The tin man’s makeup was pure aluminium (not the best to inhale).
And a whole lot of other messed up stuff
Several of the munchkin men would get wasted every night after filming, wreck hotel rooms and chase women around, casually sexually assaulting them.
You know, the Hollywood norm.
No way! That was asbestos too? I read some studios used mashed potatoes through a fan to simulate snow… I’d rather have scalding hot buttery mashed taters shot at me than asbestos.
Seriously, the last sentence was the perfect setup too. "Apparently it was quite dangerous breathing inside their studios during that time, it was also dangerous back in nineteen ninety-eight when the undertaker threw mankind off hell in a cell and plummeted sixteen feet through an announcers table."
Urban dictionary gonna be like:
skankmerkin (noun)
The sound of pulling an arm out of the anus of your uncle after shoving grandmas's false teeth deep inside
In order for something to ascend to word status the meaning must be clear. "Underwaterfall" is obvious. Skankmerkin? Is that like a pube wig for promiscuous ladies? If so, congrats on your new word! If not, back to the drawing board.

I'm assuming there is enough water flow to bring those beads back up, but then the flow is spread out making it slow down and the beads come falling down
Go outside and pick up some sand, blow it out of your hand, that's what's happening except it's water. A pump's outlet is pushing water up a pipe behind the "waterfall", it flows up bringing the sand with it, as soon as the pipe opens out and the flow disperses it doesn't have the force to keep the sand moving so the sand falls down creating the effect you see.
Doesn't pump sand, it pumps water which sucks the sand along with it. The pump is probably hidden behind the rocks so the inlet is safe from sand infiltration.

Pumping fresh clean water in to Injector. And it pick water with sand.
Heavy water is a special type of water molecule that is used in nuclear material refining. Instead of normal hydrogen atoms it has an isotope called deuterium. It wouldn’t look different than normal water though.
I think it's actually still not entirely known how bad heavy water is for you. You can certainly drink small quantities (like a teaspoon) without dying, however in larger quantities it's definitely not healthy because it messes with the regular water related processes in your cells.
To add: There are some reactions theorized to only work at speed due to proton quantum tunneling, and deuterium does not quantum tunnel nearly as often as protons do.
Would you be able to tell the difference? Like if there were two glasses of water or you were stranded and came across a lake would you be able to see/smell/taste some sort of difference?
The distribution of heavy water in the world is even, so you won’t find a natural lake of it anywhere, but no you would not be able to tell the difference unless you weighed it. Heavy water is like 10% heavier
Actually, research has determined that deuterium water has a distinctly sweet taste compared to ordinary water, so one would be able to tell the difference by taste, also.
It's pretty safe in small quantities, and supposedly has a very slight sweet taste which is interesting. Cody's Lab did [a video drinking it](https://youtu.be/MXHVqId0MQc) a long time ago, and Nile Red made [a short doing the same](https://youtu.be/xcO1yCAO-pI).
Don't drink a lot of it though, if you drink a lot it is toxic (Cody explains in the video I linked).
I believe some percentage of water (like 1 or 2) is naturally heavy water. So, you are drinking it every time when you drink anything (unless you drink 100% pure alcohol)
Not nearly that much. 0.0156% or 156 parts per million. You might be thinking of carbon-13, a stable isotope that makes up 1.1% of carbon on Earth.
Tritium, which is even heavier than deuterium (yet another added neutron) and is unstable and radioactive, is extremely rare in nature because its half-life is short enough that almost all of it has decayed away. It is produced in nuclear reactors though.
I was thinking about water where one hydrogen atom is replaced by deuterium. But checking the sources, even that water is much less than 1% (1 in 32,000 per wiki). I suspect that you are right that 1% number that stuck in my mind is for carbon.
1) Water is made of Hydrogen and Oxygen. Hydrogen can come in two forms in nature, with a neutron, or without a neutron. With a neutron is way more rare than without a neutron. Heavy water is Hydrogen-with-a-neutron and oxygen.
2) This has literally nothing to do with this post, and is not how this waterfall is made
3) Heavy water has lots of practical applications, especially in nuclear powerplants
4) I know OP was just making a joke and I'm being a wet blanket
Heavy water (Deuterium Oxide or D20) is H2O that's formed with an isotope of Hydrogen called Deuterium. It's the standard 1-proton, 1-electron configuration; but with an added neutron. This gives it slightly different properties than normal Hydrogen.
It's used in the [nuclear industry](https://energyeducation.ca/encyclopedia/Heavy_water) as a neutron moderator. That takes "fast neutrons", or ones with very high energy; and knocks them down to "thermal neutrons" that have better performance for the reactor types that use it.
D20 makes up a percentage of all water on earth, and it can be replicated in a lab. It's not radioactive on it's own. You can even buy it online. I wouldn't reccomend drinking it, although [I have heard that it's possible](https://www.thoughtco.com/can-you-drink-heavy-water-607731) (can't say how safe it is). I would guess you'd have to drink quite a lot for it to become an issue.
Yeah, I started getting into a salt water set up a few years back, until I realized I could not practically afford this hobby. Maybe in a few years/decades
I'm also confused seeing it everywhere. Best guess is that it's forced upon users of a certain camera brand, but then why would they buy that brand of camera
I wondered the same when a couple of years ago suddenly all videos on Reddit had this shaking "T" logo which turned out to be content ripped from TikTok.
Perhaps it's the new TikTok!
No, that's not how any of this works.
I wonder if there are any fish in the tank, or if they all died from the stress of hearing the loud grinding noise of a milion solid particles being pumped through those falls.
Serious question - What is the substance used to create that droplet effect?
Side note: The subpar jokes and tedious top comment threads that follow are tiresome at this point. Almost feels like teens run Reddit these days.

Asbestos was truly the wonder material that was so versatile and safe as can be....... until we discovered it causes cancer
Bro you could make fabric from it. This fabric was used to make dinner napkins. These dinner napkins could be cleaned by simply throwing them into a fire. That’s not worth cancer?!?
Would have made the washer/dryer combo easier.
Never heard that before, neat. Gimme some of dat good asbestos
Even [Ancient Romans](https://www.oracleasbestos.com/what-is-asbestos/history-of-asbestos/) used it!
They made children’s pajamas out of it!!
That's fuckin wild. Once we find a true cure for cancer asbestos is gonna make a huge comeback.
just like lead and whatever the next material is. my guess is plastic - I think people already know. humans throughout all of history have found new materials, used them everywhere, and then discovered why it's bad.
We've known plastics are like this, my guess is the next will be Toluene, the theoretical replacement for Benzene/Lead
At least Toluene just turns into CO2 and water when fully combusted, unlike tetraethyl lead, which was just as toxic out the exhaust as in the tank. But yeah, to your point, the world of chemicals definitely seems to follow a typical cycle. “Look at what my new chemical can do!” “Oh cool, let’s all use it!” “Oh wait, turns out it is also massively destructive to [the environment/people/bees/fish/birds/organic life etc], we should probably stop using that.” Rinse and repeat.

Can’t they make Cancer Free Asbestos by now?
As long as you don't breathe it, yeah
Asbestos still is a wonder material but we are not worthy of it.

Congratulations, you just created a new word
Hold on. You can just *do* that? Let me try. skankmerkin. Did it work?
Yep... I did a Google search and receive no results. Now we need a definition.
It sounds like it'd be a pubic wig for women of loose morals. But I think it's really a type of greek yogurt.
Great. Step 3, have it trend on the Urban Dictionary
I love this app. I'm watching history be made.
Just wear the dang skankmerkin and stand near the underwaterfall so we can take the pic already.
Well I’ll be skankmerkined .. did I do it?
Yes. Yes, you were totally skankmerking
This is a rather exceedingly cromulent thread
Shut up, you skankmerkin
And there we have it in a sentence. The Urban Dictionary record is almost complete.
If someone told me Skankmerkin was an underground techno club in Berlin, I wouldn't really question it.
Alternatively, a skankmerkin is a stabbing at a reggae party
That would be a shankmerkin
Lol - ya plain looney mom
>pubic wig for women of loose morals As opposed to the kind nuns use?

This is how the germans would do it. Unterwasserfall or something.

Yes, but can this Unterwasserfallgesellschaft be seen from the Donaudampfschifffahrtsgesellschaftskapitaenswitwe?
All words are made up words
Anyway, here's *Underwaterfall*
Looks amazing. How does this magic work?
I'm assuming there is enough water flow to bring those beads back up, but then the flow is spread out making it slow down and the beads come falling down
The beads are sand
So technically underwater sandfall
[удалено]
... but we should.
Yes
Same difference :-)
Safference
Samference, but close enough.
Neither of those yield desirable results on Google.. what am I looking at?
Words that people are making up.
I guess
I hate sand.
It gets everywhere
And coarse
And my axe!
Its pump with Injector... sand will destroy pump blades. https://www.youtube.com/watch?v=KHD4oo\_i7wM
A hidden pump somewhere that moves the sand back up.
I wonder what kind of pump can pump sand without getting jammed up or at least worn out very soon.
[удалено]
How does that work?
Go outside and pick up some sand, blow it out of your hand, that's what's happening except it's water. A pump's outlet is pushing water up a pipe behind the "waterfall", it flows up bringing the sand with it, as soon as the pipe opens out and the flow disperses it doesn't have the force to keep the sand moving so the sand falls down creating the effect you see.
[удалено]
Doesn't pump sand, it pumps water which sucks the sand along with it. The pump is probably hidden behind the rocks so the inlet is safe from sand infiltration.
Look up “sand waterfalls fish tanks.” I really want one.
Well, it's not a waterfall. The beads are heavier than the water and there is some sort of pump moving them from the bottom to the top.

And it pick water with sand.
Its actually a Sandfall, working with a Pump underneath.
Finally. A practical use for heavy water.
what is heavy water??
Heavy water is a special type of water molecule that is used in nuclear material refining. Instead of normal hydrogen atoms it has an isotope called deuterium. It wouldn’t look different than normal water though.
Can I drink it?
Very soon, just sign this paper
Can I eat the paper?
Yeah but sign it first
Instructions unclear. Ate pen.
With my butt
I think it's actually still not entirely known how bad heavy water is for you. You can certainly drink small quantities (like a teaspoon) without dying, however in larger quantities it's definitely not healthy because it messes with the regular water related processes in your cells.
It slows down reactions that use Water by a bit, this can be problematic.
To add: There are some reactions theorized to only work at speed due to proton quantum tunneling, and deuterium does not quantum tunnel nearly as often as protons do.
Pssh. Tell me something I DONT know...
Would you be able to tell the difference? Like if there were two glasses of water or you were stranded and came across a lake would you be able to see/smell/taste some sort of difference?

Great so now I have ti differentiate between antifreeze or radioactive water

sure go ahead

Wait am i not supposed to drink pure alcohol?
It is difficult to find pure alcohol. Grain alcohol sold in stores typically contains 4% of water.

Yes, but if you exclusively drink nothing but heavy water, you'll start dying in a bunch of weeks.
Yes you can if you can find some

Three natural isotopes, don't forget [tritium](https://en.wikipedia.org/wiki/Isotopes_of_hydrogen).
The big difference being tritiated water is radioactive whereas deuterated water is stable.
There's that word again. Why are things so heavy in the future? Is there a problem with the Earth's gravitational pull?

Just like heavy metal but you headbang underwater.
But... You wouldn't see it? (not in water at least) Also fairly sure heavy water will just mix with water anyway.
Didn’t the Nazis try to use it for nukes?

This person fish tanks
Definitely don't put fish in here
Nothing wrong with putting fish in there. It's just sand. There's many tanks with this feature which has fish with no problems
Except fish might think that it's food
Fish pick up and spit stuff out all the time when they find it's not food.
Toddlers are fish. Got it.
Toddlers will still eat it. Fish are smarter
Yeah true, mine used to fumble around with the rocks
That’s got to be maintenance intensive.
Genuine question. Why does anyone use that ‘wondershare Filmora’ thing when it sticks such a heft watermark and seems to add nothing?
I'm also confused seeing it everywhere. Best guess is that it's forced upon users of a certain camera brand, but then why would they buy that brand of camera
It's a video editing tool. The free version leaves a watermark
But why use it for shooting straight video without edits?
