Conduct chemical experiments to grow your own aquamarine crystal, glow-in-the-dark moon crystal cluster, and a crystal snow tree. Learn how crystals are formed from solutions! Display them in a collection and show them to your friends. The moon crystal cluster will grow to about 45 mm in diameter and 35 mm in height. The aquamarine crystal will grow to about 30 mm in diameter and 25 mm in height. The crystal snow tree will grow to about 70 mm in diameter and 80 mm in height. The size, shape, and color may vary depending on the experimental conditions.
