So...does your body temp lower while you're in surgery? While stuff is all open.....and stuff.....!
Science fact: The reason why ice floats is because water is one of the few molecules in nature where the solid form (ice) has a lower density than when it's a liquid. Most every other molecule, it's usually the other way around. The molecule is also coincidentally in the shape of Mickey Mouse's head, and because of that shape, the bonds when water freezes, make ice bear a resemblance (on the molecular level) to the inside of a beehive.
