Description
Grow dozens of dazzling crystals and conduct 15 illuminating experiments with this classic science kit. Experiment with four chemically different crystals each with different properties, including potassium alum crystals that form regular octahedrons, rapidly growing sodium sulphate crystals, long needle-shaped sodium acetate crystals, and plaster which is made from gypsum crystals.
Mould fun plaster shapes, including stars, lightning bolts, dolphins, and pyramids, and grow layers of crystals on them. Use dyes to form coloured crystals, and mix the dyes to grow a rainbow of custom coloured crystals.
From Thames and Kosmos, 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.
A full-colour, 32-page experiment manual guides your experiments in crystal chemistry and Earth science.
