Here are 79 easy, hands-on experiments that probe the worlds of chemistry, physics, biology, geology, weather, the human body and astronomy! It’s a book and a kit—all packaged in a bottle that makes the perfect miniature science lab: see-through, flexible, airtight when necessary…made of durable, shatterproof plastic…and designed with a removable top that doubles as a funnel. The fully illustrated, 128-page paperback book guides kids through the experiments using the included tools and items commonly found in the home. Each experiment—from creating a tornado to making quicksand—begins with a challenge and ends with an explanation of the scientific principles involved. In addition to the book and bottle, you get a measuring cup, 4 balloons, a cork and an eyedropper. Bottle measures 12 1/4" in length.
