Kosmos Grow surprise crystals yourself

Experience exciting experiments and grow sparkling crystals in a surprise color. Choose from one of three colors: violet, turquoise, or orange. Quick results guarantee fun for young scientists: the crystal grows overnight. The set includes everything you need for crystal growing, including a small jewelry box for storing and displaying the crystals. Children playfully discover chemistry through experiments with solutions. In this experiment kit, a sparkling crystal is grown overnight from crystal salt. The twist: when you purchase, you don't know which color will emerge, as only one of the three colors—violet, turquoise, or orange—is included in the set. The natural wonder can then be displayed in a small jewelry box. The easy-to-understand colored instructions explain step by step how to grow the crystals.
