Learn about the fascinating scientific phenomena behind the behaviors of these amazing materials. These simple chemistry experiments introduce STEM in a fun, authentic way. This kit Includes a test tube rack and five experiments: instant snow, crystal tree, glowing slime, oobleck and thermocolor slime. Additional experiments with the test tubes and household materials include rainbow in a test tube, gravity-defying water, acid and base indicators and more. All of the chemicals included are completely safe and non-hazardous. Kit includes 22 pieces and full-color step-by-step illustrated assembly instructions. Let it snow! Combine a special, non-toxic 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. Let it glow! Whip up a batch of slime that stores light energy and then glows in the dark! Let it Flow. 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. Let it grow! Grow a delicate crystal feather with a fast-forming crystal solution. Let the colors show! Make color-changing slime that changes from green to blue depending on the temperature. For ages 6 and up.
