Science of hot and cold

One of this month's themes is "skin". I have yet to come up with a fancy dessert, though I've been frightening my husband with suggestions for hair follicles and sweat glands...


Instead I contented myself with the most successful science experiment we've ever done. A bit too successful, really, as Elizabeth wants to do this .every .single. day. One of Elizabeth's books talks about hot and cold temperature receptors, so the experiment in question is the classic "put one hand in hot water, put the other in cold, wait thirty seconds and then confuse your brain as you plunge both into lukewarm water".
