Cultivate a color-customizable crystal you can grow in the comfort of your own home! The kit includes everything you need to get started and to view your crystal's progress as it slowly shapes and forms to its own unique size and pattern. Includes multiple color packets, meaning that mixing different amounts of each color packet produces differently colored crystals! Get a few kits and create a rainbow crystal garden! Also includes a viewing jar in which to let the crystal grow. The finished crystal should measure about 5cm (2in) x 4cm (1.5in), though the size, shape, and color will vary according to experimental conditions.
