Hand vs. Liquid Nitrogen and the Leidenfrost Effect

I stick my hand (momentarily) directly into liquid nitrogen but don't suffer any injuries 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.

You should begin your videos saying:

"Do not try this your self. I am your father"

no oil boils cooler than water, thus the leidenfrost effect doesnt happen in that case.

You don't need to edit your voice to let us think your tough.

Your knowledge of the Leidenfrost Effect is more than enough to prove your manliness.

You should go back to school and learn English again. I can barely think of what you're trying to tell me. I'm gay? Well i guess someone has a problem with gays, I'm not saying i'm gay myself, but Gays are are human as any other human. They're made of the same kind of matter that first started out in this universe. Fuck off man.
