Explore the greatest hits of the Ooze Labs series along with some cool new experiments. Outfit your chem lab with five big and sturdy plastic test tubes and a test tube rack to hold them, and then launch into your exciting explorations: Combine a special, snow powder with water and watch as the mixture expands to hundreds of times its original size, creating a light and fluffy material resembling snow. Mix your own oobleck, a mysterious oozy substance that behaves a little like quicksand. It is a rigid solid under force but runs like a liquid when no force is applied. Grow a delicate crystal feather with a fast-forming crystal solution. Learn about the fascinating scientific phenomena behind the behaviors of these amazing materials. All of the chemicals included are completely safe and non-hazardous. A 20-page, full-color experiment manual guides you step by step through the experiments.
