Crystals are fascinating creations of natural beauty. Diamonds, gemstones, rose quartz, snowflakes, sugar grains, and table salt are all crystals. Grow your own crystals and explore these exquisitely ordered structures in a fun, creative way with six crafty experiments. This kit includes five different chemicals and other tools for growing crystals. Grow a crystal cloud inside a rainbow. Watch pink iridescent crystals form from a translucent solution. Grow long needle-shaped crystals. Mold plaster hearts and flowers and then grow a layer of pink crystals on them. Create the perfect solution to get crystals to form on a granite rock. A specially designed experiment station provides molds and growing basins for your crystal creations. After you have grown your crystals, store them safely in three clear, locking display boxes. Learn how and why crystals form, and tips and tricks for getting the biggest, most beautiful crystals. Full-color, 16-page experiment manual.

Explore the natural beauty and wonder of crystals by growing them yourself in many different shapes and colors. Set up your lab base station — the headquarters for all your crystal growing experiments, complete with beakers, test tubes, petri dish, tweezers, centrifuge, display dome, and more. Then conduct more than ten experiments in crystal formation, using safe, non-toxic crystal salts.

Make a crystal volcano by growing fast-forming crystals on a paper cone. Watch long spindly crystals form on a rock as if from nowhere. Grow crystals in many different ways, such as in a petri dish by evaporation, on a string dangling in solution, and by cooling a supersaturated solution. Experiment with three different chemicals, each resulting in different crystal shapes: monopotassium phosphate, ammonium dihydrogen phosphate, and potassium aluminium sulfate. Mix your own colors for your crystal growing solutions in the spinning centrifuge, so you can achieve a variety of different colors: red, pink, blue, purple, and clear. Learn about how crystals form in your experimental solutions and also in nature.

After you have completed the experiments with the materials in the kit, you can continue using the lab station and equipment for your own crystal-growing and chemistry experiments, using common materials from around your home like table salt and alum salt.

Combine the base station with the base stations from the other Ooze Labs kits (Chemistry Station, Soap & Bath Bomb Lab, and Alien Slime Lab) to make one awesome laboratory setup!
