Grow dozens of dazzling crystals and conduct 15 illuminating experiments with this classic science kit from Thames and Kosmos. 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, 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. Then, display your crystal creations in a clear treasure chest with a locking lid.
This kit allows you to investigate solutions, crystallization, and the chemistry of crystal growing, and learn about the structures and geometries of different crystal shapes. This popular kit has sold over one million units worldwide, and is thoroughly kid-tested and safe. A full-color, 32-page experiment manual guides your experiments in crystal chemistry and Earth science.
