Just add water for hours of learning fun. In this Bag of Knowledge you'll find fun science supplies with experiments, ideas, and explanations.

Super Snow, Space Sand, Neon Space Sand, and the World's Simplest Crystal are all included. Super Snow lasts for weeks, is totally reusable, and looks like real snow. It's been used everywhere from movie sets to indoor snowboarding parks, and more.

Space Sand, the closest thing to soil from Mars that most of us will ever experience, will not get wet and can even be formed into shapes under water. Remove it from water and watch in amazement as it miraculously turns to completely dry sand.

Also play with Neon Space Sand for more out of this world colors. The Simple Crystal is also fun to watch as crystals are formed by a completely safe reaction as the vinegar evaporates.
