Crystal Growing Kit by Thames & Kosmos

Availability: In stock

Grow dozens of dazzling crystals and conduct 15 illuminating experiments!

The 15 experiments progress from simple to complex, providing the perfect learning experience for new chemists. A full-color, 32-page experiment manual guides your experiments in crystal chemistry.

Experiment with four chemically different crystals each with different properties. Mold fun plaster shapes, including stars, lightning bolts, dolphins, and pyramids, 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 — a hollow rock with crystals growing inside — and create a beautiful crystal cavern inside.

 Learn about the energy of crystallization. Investigate solutions, crystallization, and the chemistry of crystal growing. Learn about the structures and geometries of different crystal shapes.
