Crush a steel drum with air pressure 

legit why I'm here lol

Yeah I wonder why 🤔

Idk what for. People be so slow to learn until it goes viral. That's why they're disabling comments on these videos. Lmao

Also realize that this experiment shows the difference of only 1 atmosphere difference. At the bottom of the ocean near the Titanic, the pressure is about equal to 400 atmospheres, or 400 times the pressure you experience on the surface. If you think this visual is dramatic, just imagine that at 400 times as violent.

Inbreds

It's called a submarine

or carbon fiber, lol.

New idea. Pure plastic submarine using an Nintendo Wii controller

Yeah, people whom see this type of experiment, and don't understand atmospheric pressure really have no idea just how FAST AND VIOLENT that sub implosion really was, no idea.

​@@williamh6547it literally crushed them n they had no idea

So hundreds of kilos of air pressure are 'pushing Down on us', What is preventing all that pressure from dissipating + expanding while it pushes Up + Out against the infinite Vaccuum of 'Space' ?

@@swamplifecontrol Earth's Gravity. Gas is also pulled towards the Earth by gravity. Without gravity exactly what you stated would happen, all our atmosphere would migrate out into space.

@@peterschmidt1453 Or maybe it's something else _ since "These three forces are enormously powerful but operate mainly over short distances. Most important to physicists, all three can be neatly explained by the theory of quantum mechanics. Gravity is different. Physicists can’t quite wrap their heads around the graviton, the quantum particle of gravity that’s almost impossible to detect. Needless to say, all of this makes gravity - and the search for the graviton - a core challenge of contemporary physics." ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Zz95_VvTxZM.html

@@swamplifecontrol Gravity lol

N someone said that they lost balance control n where rolling around on top of each other. So its not like they where just sitting in one spot the sub was turning and going down like an arrow at the time n then it leaked water n then imploded with out them knowing what was going on. They where all crushed on top of each other. Now there's an image for ya.

It's probably much less than a 1 atmosphere pressure difference. Which makes it even more impressive. --Carl

Unless they couldn't breathe.

did u do it with another 4 ppl under 3800m sea?

@@kenho-wr5ul2rh7m not funny, but appropriate

I was thinking they should let the 2-liter bottle warm back up and show it expanded! So cool you take the experiment further than most. Just an unrelated side note. I remember one winter I had bottled water in my car, but the water wasn’t frozen. I took a bottle into work one day and when I put it on my desk it immediately froze! I was like wth just happened??? Lol. Looked it up and found out it was super cooked water. I thought it was so interesting!

Huh, That an intersting idea. I wll have to give that a try! --Carl

Pressure imbalance is not the only criteria to implode the object in question. The object (the can or the drum ...) will implode if the pressure difference is greater than the materal can withstand.

you rushed with your conclusions there

Yeah, more teaching like this instead of teachers filling kids heads with left wing wokery and how to be easily offended.

Even creepier is that we live at the bottom of an ocean of gases that is 80% toxic to us...most of the air we breathe is composed of nitrogen

Yes , a square metre of air in a column 120,000 ft high, weighs about 10 tons .

Even slowing the video to .025x speed it gets crushed instantly so it’s really fractions of a second mindblowing speed

Lol it dose look like it if your not focused on him lol

How did that work out

Not FBI you can get it at your local KFC

Depends on your definition of "very."

obviously a maximum of 1 bar. because the only pressure here is the external atmosphere. inside, it can only reach zero, it cannot be negative. suction does not exist per se, its just inferior pressure. just like there exist a temperature zero, btw. and yes, we re all thinking at the same thing. for the sub, it was around 300 bar.

It is greater then zero and less then 1 bar.

Probably less than one atmosphere. Next time we do this I will add a pressure gage to the small port on the drum to determine pressure inside the drum. --Carl

It’s real its not edited

When the water boils, the steam created fills the container, pushing the air out. Since the steam is a gas, it expands to fill the space and ends up taking up about 1000x the volume of the liquid water. Eventually it starts coming out the hole. The cap is placed on. Then when exposed to ice and cold water, the drum cooled enough for the steam to condense back to water. But it only takes up about 0.1% the space as the steam. The other 99.9% is nothingness --- a vacuum. So this isn't a "slight difference in air pressure," as he suggested. It's the difference between 14.7psi and just above 0 psi.

@@arvia1984 thank you. That’s a very big help

@@Ramiristempest It is exactly how the early stationary low speed atmospheric steam engines used to work ( for pumping water out of mines etc ) steam filled the cylinder to push a piston up , then they cooled the steam in the cylinder which condensed causing a partial vacuum which allows the atmosphere to push the piston back down. Here's how it works . ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GMgP-4O99qU.html Technical explanation at 3:40 .

@@WildPhotoShooter thanks. Btw, if I'm interested in these kinds of things, what major should I take? I need some advices

@@Ramiristempest I couldn't advise you on that, you would need to decide what discipline of physics you wanted to spend your career in.

That's just how fast air is. Just look at the videos of people doing similar with a soda can. It really is instantaneous. Plus you can see a car move in behind the can right before it implodes and appear in front exactly when expected. So no cuts here.

@@Skylancer727 ik I was joking😂but thanks

I think you are wrong, once a weakness formed in the hull of the Titan the collapse would've been instantaneous because its strength would have been completely compromised and 400 atmospheres per square inch ( equivalent to about 4000 tons over the whole surface of Titan ) collapse would have been instantaneous. The crew might have heard a creaking for a second as the hull failed, but I don't think they would even have had time to ask each other what the noise was. Carbon fibre snaps like a carrot when it fails.

@@WildPhotoShooter Do you think that if the pressure hull was made of steel instead of carbon fiber , would the deformation be gradual as well as the failure ?

@@zehravigna4873 Nope, even in a steel hull once the strength is compromised and fails the collapse would be just as fast until all the air has been expelled ......we saw how fast the 45 gallon drum failed when its strength was compromised . A human body would collapse and implode just the same at the depth the Titan was at, our skull and rib cage would collapse like an egg shell.

@@WildPhotoShooter This gallon imploded very quickly because it was not thick enough, in other words his stength was not strong enough. If this drum was made of a very very thick steel the implosion would not be as sudden as on the video. We may have even observed the deformation. It is my opinion.

@@zehravigna4873 Anything would implode with exactly the same speed when it reached its design limit , even a modern nuclear submarine would fail in exactly the same way if it went too deep.

He said he had boiled the water before starting the filming, so it just needed a little extra to get it boiling again, maybe you missed that part .

Well, thats pretty unlikly. The cap screws into the barrel, the hardest part is screwing the cap into the drum. --Carl

this was a makeshift experiment just to show how it works. you arent going to get the drum completely empty of air unless you are in a lab environment with special equipment and rooms. You sound like the clown.
