Why does hot water freeze faster than cold water? Royal Society of Chemistry offers reward for explanation | Fox News
Which reminds me of something i "discovered" a few years ago. I dont drink much soda, but every now and then i like a coke a cola. And when i treat myself to a coke i like them really really cold, so ill put them in the freezer for a little bit. Well one day i did it with a plastic coke bottle and when i opened it and i guess kind of bumped it, the thing just crystalized in front of my eyes.
Its called supercooling and its nothing special but i had never noticed it before and thought it was pretty neat. If you have kids it might be something cool to do with them. You got to cool it to the point right before it freezes but i dont think its all that hard to time it right.
