Title: Hand vs. Liquid Nitrogen - Revisited
Added: Jul 19, 2010
Author: NurdRage
Duration: 5:6
Description:
I go back to sticking my hand into liquid nitrogen but remain uninjured due to the Leidenfrost effect.The Leidenfrost effect is the formation of a gas barrier between a hot surface and a boiling liquid if the temperature difference is great enough. This gas barrier greatly slows the heat transfer between the two and allows the liquid to last longer and consequently the hot surface to remain hot longer. This effect can be seen in a frying pan as it's being heated. At first the water quickly boils as it's dropped in but at a hot enough temperature the Leidenfrost effect takes over and makes the water skate around the surface lasting a very long time.Liquid nitrogen vs. a room temperature object will also exhibit the effect preventing it from instantly freezing the object... such as my hand.

Kiqertage Says:
Apr 29, 2012 - It's just a cool thing. And its toxic if its ingested. I doubt he's going to eat it. And actually it doesn't need top be heated up that high. I'm pretty sure he's got the equipment.

May 20, 2012 - Why can't we try this at home? Just curious..

May 23, 2012 - It's a liability thing, in a way. If you try it and your hand freezes and you pick up the phone but hit it too hard so your hand shatters, you can't blame Nurd Rage because they said "not to try it at home." But you can do it, at your own risk.

May 24, 2012 - I tried it and my hand is fucked
