Create your own crystal cave inside an aquarium with the Discovery Crystal-Growing Aquarium STEM kit! Set the stage for your crystal cave by attaching the included backdrop on the outside of the aquarium. Then, remove the growing rocks from their bag, plan out a color scheme, and place them inside the aquarium! See a simple chemical reaction in action after pouring the included crystal-growing mixture into the aquarium - after a few hours, the rocks will grow into long, cave-like crystals! While your crystals grow, decorate the aquarium with stickers to really bring it to life. Explore the fascinating world of crystallography with the included bonus poster, and discover the science behind all kind of crystal formations - even your own! The Discovery Crystal-Growing Aquarium kit is perfect for any young scientist ages 12 and older.
