Grow dazzling crystals and conduct 15 experiments with this crystal growing science kit from Thames and Kosmos. Discover the various properties of four different types of chemical crystals: potassium alum, sodium sulfate, sodium acetate, and plaster made from gypsum crystals.
Investigate rapid and slow crystal growth and observe the effect on crystal structures. Try to grow many small crystals and one giant crystal. Amaze your friends and family with a "geode" made from plaster and filled with crystals! Finally, display your creations in the included treasure chest with a locking lid.
Experiment with crystallization, solutions, dissolution, and the chemistry of crystal growing. And study the structures and geometries of different crystal shapes.
This 26-piece kit includes a 32-page manual for doing 15 crystal-growing experiments plus chemicals, molds, dye, measuring cups, safety goggles, and more. You supply distilled water and common household items. Ages 12 and up.
