Your child will learn good science information from growing crystals! You make a solution and actually see results of something called “precipitation,” and evaporation. You also learn about molecules, how different types of crystals form, and why different crystals look the way they do. Your child can experiment finding a favorite crystal solution formula! You can grow your very own crystals right at home. Unlike almost every other crystal growing kit out there, Crystal Explosion doesn’t need a stove or a microwave – just add hot tap water and stir in the Crystalizer mix. Also, the chemical isn’t scary and toxic like most other crystal kits! Put your cup in the fridge, and within 24 hours it will be full of beautiful needle-like crystals. Included are two more fun experiments, and enough materials to do each one again! The final experiment grows an awesome mega crystal! See also Polymer Power for more science experience.
