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