Go liquid nitrogen!

Ahh yes, liquid nitrogen day today was good fun. It was really only an hour, but meh. We froze stuff and smashed stuff, brilliant. There were eggs, a potato, some flowers, lemonade, balloons, my sandwich, a can, steve's coke bottle... most were hit with a hammer shortly after their being frozen. The potato was particularly spectacular, it got thrown at a wall resulting in some nice shattering. Liquid nitrogen makes such cool clouds as it evaporates. Actually I found it quite interesting that you could just leave it out in an open container and not have it all evaporate away instantly. The sides were well insulated so i guess the cold air was so cold that it stayed in the container with the nitrogen.
Found out I aced my last two tests today too, was quite happy about that, specially the mechanical eng one since that subject is actually one of the more complicated ones. Not that any of them are terribly hard, but since I do no study except just before tests I don't get perfect marks in all of em.
Ahh yes, and another quiz, stolen from seans blog:
