Via my friend Davis comes this fun idea for a science experiment from Scientific American. It can teach your kids (or you!) about the power of evaporation by using some water to keep a chocolate bar cool, and you get to eat your results.
The experiment is especially perfect for this time of year, as you need two identical bars in their wrappers. I hope you’ve still got some leftover fun-sized bars from trick or treating! If you’ve eaten them all by now, you may have a future as a candy blogger yourself.
