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.

I remember seeing …
I remember seeing someone wetting his hand and then putting it on boiling lead just like this guy did with the nitrogen. Could it be the same effect described here (in this case, the lead is so hot that the water on the hand protects it?)

thats why he takes …
thats why he takes breaks in between pours. repeatedly pouring it on would develop a relative cooling process, it wouldn’t have to cool from “hot” each time if he didn’t do it with breaks. the first time would be hot, the second warm and the third cold so on and so on which would then freeze his hand.

i know it takes …
i know it takes time about 7-15 seconds to %100 freeze your hand without the leidenfrost effect.i have played with liquid nitrogen its fun,i put a soda can in there i dropped it and it smashed into a million pieces

@RottSimba You have …
@RottSimba You have obviously never played with liquid nitrogen before. It DOESN’T freeze your hand instantly!

I am so sorry, but …
I am so sorry, but it’s pronounced l-eye-den-frost, not lee-den-frost.
Every time I hear the word mis-pronounced it feel like hurting people.

So if you were to …
So if you were to make contact with the nitrogen droplets on the floor will it cause a frostbite,or just slide away as your hands are also of a body of very much higher temperature in the nitrogen’s perspective??
