Product Details

Learn the chemistry behind crystal growing while creating dozens of sparkling gems worthy of display! Experiment with four chemically different crystals, each with different properties, including potassium alum crystals that form regular octahedrons, rapidly growing sodium sulfate crystals, long needle-shaped sodium acetate crystals, and plaster which is made from gypsum crystals. Mold fun plaster shapes, including stars and lightning bolts, and grow layers of crystals on them. Use dyes to form colored crystals, and mix the dyes to grow a rainbow of custom colored crystals. Display your crystal creations in a clear treasure chest with a locking lid. Mold your own geode and create a beautiful crystal cavern inside. Experiment with growing crystals rapidly and slowly, and observe how that affects the crystal structures. Learn about the energy of crystallization and the structures and geometries of different crystal shapes. A full-color, 32-page experiment manual guides you through 15 different experiments. This kit is thoroughly tested and safe, with over one million units sold worldwide.
