"Rocks that grow YES! Right before your eyes! In addition to the eyepopping fun, this is a great introduction to the wonder of science and the science of crystals. And its easy. Simply combine the two included ""growing chemicals"" with hot water, pour over the seed crystal, and watch the magic happen. Youll 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."
