Halloween has come and gone, and there are bags of leftover candy to prove it. Once you’ve had your fill of the sweet stuff, you can have plenty of fun with the leftover Halloween candy with science experiments! From sorting games with young children to candy chromatography, there is plenty to do with leftover Halloween candy that doesn’t involve consuming all that sugar. An all-time favorite experiment is finding out what happens when you soak gummy candies in water and other liquids. It might be fun to measure and compare different brands and colors, too.
