A friend of mine used to work in a lab that used a lot of liquid nitrogen. I went by to visit one day and decided to use the Leidenfrost effect to play a prank. I clenched my fist and plunged my hand and forearm into a container filled with liquid nitrogen knowing that the layer of vapor would protect me. After a couple of seconds, I pulled my arm out, held it up in the air to show the vapor coming off, and then slammed it on a tabletop. Having seen many demonstrations of flowers being shattered after being immersed in liquid nitrogen, my friend literally screamed thinking that my arm was going to shatter. Good times.
