These incredible pebble-sized polymer crystals mysteriously turn into pieces of gel-like goo when you add water. These crystals absorb 150 - 300 times their volume in water, and they're reusable. The instructions are packed with intriguing activities that make great hands-on activities or science projects for students. Each package, when mixed with water, creates approximately 1/2 gallon worth of crystals.
