First observe how pre-grown crystals dissolve inside a clear acrylic cave. Then turn the CRYSTAL CAVE around, and watch them grow again - right before your eyes - like stalactites from the cave's ceiling down. Repeat as often as you wish! Powered only by gravity and ordinary changes in room temperature. Includes 48-page full color instruction booklet about caves and caving. (Age 12+) |
