"In a series of fun and involving hands-on chemistry experiments, kids observe the effect of molecular motion, try to inflate a balloon inside of a bottle, demonstrate the cleaning of water by capillary action, discover how detergent causes other molecules to move, and make water appear to boil with only the touch of a finger. They will also demonstrate how salt makes it harder for water to freeze, learn how to grow salt crystals and how to produce an elastic material, and observe liquids that will and will not mix together. Featuring color illustrations and safe, simple step-by-step instructions, Janice VanCleave again shows just how much fun science can be"--From the publisher's web site.
