I am a 7 grade science teacher and I was wanting to give a lesson of some
chemicals that would cool or heat slighty when they became wet with water. I
found the name of the chemicals that heat up with water but I need some
suggestions for chemicals that will turn cool to the touch when it becomes
moist. I need the chemical to be NON TOXIC and not be dangerous for handeling.
Thank you.
