Prove scientifically that all that glitters is not gold
Mold your own geode and create a beautiful crystal cavern inside – this is just one of 15 experiments composed of four chemically different crystals: potassium alum crystals create regular octahedrons; rapidly growing sodium sulfate crystals; long needle-shaped sodium acetate crystals; and plaster made from gypsum crystals.
Create plaster casts of shapes and then grow layers of crystals on them. Mix the dyes (included) and custom color your creations – then display them in the included clear plastic treasure chest.
Includes 15 experiments, locking treasure chest and instructions.
Recommended for ages 12+.
