Add water to this granular white powder and watch it instantly expand to 40 times its original volume. The result is a fluffy artificial snow that feels as cool as it looks! Our snow won't "melt" but it can be dehydrated and re-used. Great for teaching endothermic and exothermic reactions or as part of a polymer lab. This is a great demonstration of interest to students and educators of ALL ages and abilities.
