Man puts hand into a vat of liquid nitrogen

Pretty incredible. though I understand the science behind it, I still wouldnt do it.

Protected By ScienceMy hand is like a red-hot poker to the liquid nitrogen, but an insulating layer of nitrogen gas forms- a phenomenon known as the Leiden-frost effect- keeping my hand safe and warm for a fraction of a second.Mike Walker

I was hoping to see him shatter his hand on a table or something.

I would be too chicken to try it, but I don't see why you wouldn't be able to do this if you were fast enough.

Did he know at the time it was liquid nitrogen?

thats pretty cool

Here is a more detailed breakdown of whats happening.

I was expecting to see a picture of a hand shattered into a million pieces, but this is cool, so basically is none of the liquid nitrogen coming into contact with his skin?PernicioEnigma

That's the gist of it.

every knows that trick, you can even do it with molten medal. I was hoping for an idiot who froze his hand and got destroyed.

That was pretty awesome.

Same here, but it was still a very brave and cool thing to do. GrandJury

No pun intended?:P:lol:

So if he left his hand in there... how long does it have?SolidSnake35

I can think of ways to make it a bit more extreme :P

It'd make a great party trick or dare 8)

It also works with (really) hot molten lead as the mythbusters have demonstrated. NOTE: IF YOU HAVE YOUR HAND WET. Molten lead doesn't create a protective gas barrier lol. You need water for that.

Oh man. :lol:

No it wouldn't; haven't you seen the old frozen banana demonstration? You only have as much time as it takes for your hand to get cold enough such that it no longer instantly evaporates liquid nitrogen, at which point you get a hand just as frozen as the banana.

That's just reckless. Although people who perform stunts don't really care about what could happen if they screw up. We had Nitrogen in my High School vocations. Our teacher was lucky nothing bad ever happened, because we were misfits and henever paid attention to our shenanigans.

I don't think we were supposed to have it. It's good for demolitions and cooling things down but for as much as we had I think he was ripping it off. I think that's what happens in most of those vocational courses. So I'm guessing that's why we got away with it.

I wouldn't do it.

This thread disappoints.

I read this as "head" and my hopes where let down :|

Mythbusters did a similiar sort of thing with Molten Lead.ace-of-spades93

Yeah, I remember that episode too. It's pretty awesome science.

The Leidenfrost effect is a lie!

Let's see who can keep it in longest

Very interesting, but I would never try this myself.chessmaster1989

That was cool. If I did I would end of fall over and knocking it all over me. I bet it would be very painful.

Dipping your hand in a vat of molten lead is more impressive.
