Crayola Tie Dye Color Chemistry Set

My boys have enjoyed doing their 'experiments', although it says over 50 experiments some of them are pretty easy and are over quickly. The explanations and descriptions of the experiments are easy to understand for the kids and are in depth. My only complaint is that in one of the kits we purchased, the clay for the volcano was wrapped in tissue paper making hard to peel off the clay. We lost a 1/4 of the clay to the tissue paper, but still had enough to make a decent mound. Would recommend and would buy again.
