Also broke the weatherman's toes.
Actually this was the principle used for the first steam engines, the cylinder was filled with steam while the piston was at the bottom dead centre and then the steam was cooled down. This sucked the piston up unlike modern days when we tend to push the piston down. Newcomen atmospheric engine worked on this principle. Through a feedback system the sequence was repeated to produce shaft power.
Considering that the atmosphere produces a pressure of 15 pounds per square inch, then one foot square, when the inside of a container is a vacuum this will produce 1710 pounds .
Now in wing sections of a plane one tries to deflect high speed air to produce partial vacuum on top of the wing and higher pressure under the wing, If one assumes that we could produce a good vacuum on the upper side of the wing while keeping atmospheric pressure under the wing, this will lift up a lot. Just imagine, one square foot could lift up five people and their luggage! That is the reason why the wings of planes appear to be so small to lift up more that 500 tons even up to nearly 1000 tons of weight.
To think that we are like fish swimming in air and breathing it all it, makes one wonder how we can take this pressure when it comes to light when we dive under water. That is another subject which one had to understand before diving at depth underwater.
That reminds me of shampoo bottles in the winter
Nice sir. Sir may you tell me that can I used this drum for 22psi steam pressure.
The funny thing is that at ground level it's about 14psi around us all the time, our bodies are pushing back. especially my stomach on bean night.
One word... Cool

*_Barrel Gets Dents_*
Not so strong
Glad there's no acetone in there before he lit up
cityamish1 That's why we rinse the barrels out with water before doing this demonstration. --Carl
You can tell he wasn't sure it would work. He used the tough barrell as an excuse just bang dents in it.
you can tell hes not a man thats used to swinging a sledge with how close he went to the guys foot with the first swing
Hi Jim,
I agree, I'm a man of science. Not used to breaking things up with a sledge hammer. Gimme a beaker instead! :)

You can use a torch like that at home I'm 14 and I own one half as big it just takes common sense
Nice video
Could put steam in a piston cylinder seal it pull the piston pull a crankshaft and pull energy out of the whole system of entropy
Bet that paint smelled good when he took a torch to the can.
And now Mythbusters is gonna do a whole taker like this
+Darkkmos There are no more Mythbusters
+TopherFM I'm all too well away (¡~¡)

Big, they imploded a tanker trailer.
It doesn't look super tough to me... LOL
exactly, lol
I realllllly want to see someone try this with a giant tanker, maybe an oil tanker rail car or 18 wheeler tanker. I have no idea how one would accomplish it let alone if it would even work but it would be cool to try
P0tat0_craft Wouldn't work right because you need a hollow tank for this to work. Those large tanks you mention have inner structures that would act as support to keep them from being crushed.
That said, watch this one: watch?v=2WJVHtF8GwI
6p I was 4th St Paul is just lkz 6grvu😄😄💲
They're trying it on the next season of Mythbusters
Mythbusters did it :)
P0tat07 worked at a place where we drained asphalt out of rail cars and if we left the lid on the rail car while we were heating and pumping the car into big tanks it would compressor and crush under the vacuum the pump created
How long did you heat the Drum?
rub your hands on it
Question: couldn’t he just have put the barrel in the ice without pouring the water in since the air inside (which consists of nitrogen, oxygen, argon, and co2) would then cool down and thus create the necessary pressure imbalance triggering the crushing by the outside pressure?
I’m confused..
Those gasses would condense but they wouldn't liquify and reduce the atmospheric pressure inside the barrel enough to really cause any changes. The water vapor caused most of those gasses to exit the barrel and be replaced by the vapor. Putting the barrel filled with water vapor on ice caused the water to liquify, reducing the pressure inside the barrel allowing earths atmospheric pressure to crush it.
@@maxgucciardi9054Nonsense. He puts WATER inside, which is then heated to STEAM, then the drum is cooled to condense the STEAM back to WATER. The ice simply speeds up the cooling of the steam, but it could be allowed to cool simply by heat exchange with the drum and the outside air. It would take longer, but the result would be the same. “The gasses would condense but not liquify”? condense into WHAT? there’s no interim state, unless you’re talking about a brief moment at the triple point or a supercritical liquid which isn’t an official state of matter 0 it’s gas or liquid, FFS.
i bet that burning paint smells great. good for ya too
So you tell me that I crushed one of those barrels with 3 stomps of anger and everyone struggles to crush it with a sledgehammer bare in mind it was full of sticks and other metals as well as random trash
viu chem 150
These steel drums are way too big to step on!
This is what will happen to a Hyperloop or any other vacuum/low-pressure assisted transport.
Woosh, you don’t understand the principle at all, congrats.
revers it and rip the can open
