Awesome videos! I would love to see this same principal in a steam engine. Have a normal small example of a steam engine boiling water to power it. Then remove the flame and replace the water with liquid nitrogen.

*pop* reload!

[Astanize]

make this into a machine that dispenses the liquid nitrogen into the flim canesters, and you have yourselves a CAP gun. lol get it....

[Zims1andonlyMik]

when the lids of the canisters pop off, what is coming out of them? is it just nitrogen gas, or is it liquid nitrogen and nitrogen gas?

[JeffersonLab]

Some of the liquid nitrogen comes out, kind of like how water can come out of a glass if you slam it on a table. The liquid nitrogen then cools the air which condenses the water vapor, forming clouds/fog. This is mainly what you're seeing. Nitrogen gas is coming out, but it doesn't look different than normal air.

ok, thanks for clearing that up for me! ^^

[lyzergnature]

the caps fly from the ground to the table!

[JeffersonLab]

What now?

[lyzergnature]

hahaha

What would happen if you put your hand on the actual nitrogen?

[JeffersonLab]

If we were to touch a small amount of nitrogen for a small amount of time with our bare hands, we would be fine. We are so much warmer than the nitrogen it would instantly boil once it touched us. It would end up creating a thin layer of gas between us and it. Since the heat capacity of gases is low, it wouldn't cool us down very quickly. If the liquid remained there or became trapped, it would freeze the skin it was in contact with. We have a second or two before bad things start to happen.

There is a name for it but i forgot it!!

[JeffersonLab]

The Leidenfrost effect.

[SaYiPwNuHomes]

i have a question since these lids can pop off it does since the presure is so high but if u have something that completely seals it and is locked with a lot of presure and nothing can get out what happens?

[JeffersonLab]

If the container doesn't fail, one of two things would happen. (1) All of the liquid would change to gas and you would end up with a container full of high pressure gas, or (2) the pressure increases to a point where the liquid nitrogen stops boiling, even at room temperature, and you end up with a container partly full of high pressure gas and partly full of high temperature liquid nitrogen.

I was the other way round my physics teacher found these vids b4 i did

[eduardodc3]

Simple and very nice experience!!!

I like it !

[bensonak47]

lol i love how u put another cap once the first one popped off

[tutorialconr]

I want to favorite ALL of your cool videos =) we want more!

[stefanjenouski]

i love all your videos im tellin my chemistry teacher about these videos :)

[JeffersonLab]

Thanks!
