Anyways, we did a science experiment this week with "blubber". It was really Crisco (or as in our case, an off brand version). First, we put our hand in ice water by itself. COLD! Then we added blubber (fat). Blubber is a thick layer of fat under the skin in polar bears and dolphins (we learned that earlier this year). With tons of blubber (which you have to pile it on thick), the fat helps keep you warm. :) Girls had fun with this! But it was very messy to wash off!
