Why is he reporting temperatures in Fahrenheit? Yuck.

So basically nothing happens in this video... put anything in liquid nitrogen and it boils more. Its fun to play around with. Also take some water with soap in it, and throw in a brick of dry ice, that is fun too.

Fun fact, you can pour liquid nitrogen on your hand and it will not hurt you. Your body temperature is so high that the liquid nitrogen forms a layer of gas between your skin and the Nitrogen, it will roll right off. Not so fun fact, if you cup your hand the liquid nitrogen will burn (freeze) it very badly.
