When it comes to kids and science, one law remains constant: They can't turn away from a cool chemical reaction. Let them discover the wild world of crystal growing with these two DIY kits. The paper volcano and coral pieces soak up the terraforming (a.k.a., "earth-shaping") solution, and then the magic, er, science happens. Efflorescence will occur--that is, the water will evaporate, leaving fractal crystals behind. Less water = more crystals, which means kids can watch them encrust their island landscape in real time. Made in Taiwan.
WARNING: CHOKING HAZARD - Small parts. Not for children under 3 years.
