Thinkbox, Crystal Aquarium

Create your own crystal cave inside an aquarium with the Think Box Crystal Aquarium kit! This hands-on kit includes magical crystal-growing rocks, a ready-to-go crystal-growing mixture, and an aquarium to watch the crystallization process in action. It’s an awesome introduction to earth science and makes a fun rainy-day activity for kids! Remove the growing rocks from their bag, plan out a color scheme, and place them inside the aquarium to see a simple chemical reaction in action. 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 kinds of crystal formations — even your own! The Think Box Crystal Aquarium kit is perfect for any young scientist ages 12 and older.
