Product Description Grow dozens of dazzling crystals and conduct 15 illuminating experiments with this classic science kit. Mold fun plaster shapes, including stars, dolphins, and frogs, and grow layers of beautiful crystals on them. Use red, blue, and green dyes to form colorful crystals, and then mix the dyes to grow a rainbow of custom-colored crystals. Mold your own geode — a hollow rock with crystals growing inside — and create a stunning crystal cavern inside. Display your crystal creations in a clear treasure chest with a locking lid. Experiment with growing crystals rapidly and slowly, and observe how that affects the crystal structures. See if you can grow one giant crystal and many small crystals on the surface of a rock. Safely investigate solutions, crystallization, and the chemistry of crystal growing. Learn about the structures and geometries of different crystal shapes, as well as interesting historical and cultural information about crystals. A full-color, step-by-step illustrated experiment manual guides your experiments in crystal chemistry and Earth science. Directions Includes a 2023 updated 32-page, full-color manual with improved usability and a fresh design, guiding users through crystal chemistry and Earth science experiments with step-by-step illustrations.
