Hand vs. Liquid Nitrogen - Revisited
Loading...
Uploaded by NurdRage on Jul 19, 2010
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.

I really wanted to watch you freeze your hand and then shatter it with a hammer terminator style.

@thebestofall007 I imagine that's why the treatment is not instant. My derm took his sweet painful time taking the latest one off my finger.

does the leidenfrost effect apply when freezing off warts?
-
@dopplerable Ask whoever first said that. It evaporates at approx -195 C, WAY below room temperature, so it can't possibly remain a liquid on/in the floor. It will mix with air quite readily, although it might be possible to displace enough oxygen in a confined space to be dangerous- if you work at it hard enough.

That shit cra
