Curious Minds

Rocks that grow ... YES! Right before your eyes! In addition to the eye popping fun, this is a great introduction to the wonder of science and the science of crystals. And it's easy. Simply combine the two included 'growing chemicals' with hot water, pour over the seed crystal, and watch the magic happen. You'll see exciting changes in the first few hours, and the growth process will continue for about two weeks while the approx. 3"tall crystal almost doubles in size. Fascinating fun for ages 12 and up.
