The Pop Bottle bottle is a perfect miniature science lab:-see-through, flexible, air-tight when necessary, made out of a durable, shatter-proof plastic and designed with a removable top that doubles as a funnel. The Pop Bottle book is a lively, fully illustrated 96-page guide to astonishment. Each experiment begins with a challenge and ends with an explanation of the scientific principles involved. Kids can design a volcano and watch it erupt. Create a tornado-maker and see how twisters work. Make quicksand - is it solid or liquid? Observe photosynthesis in action. Simulate Jupiter's giant red spot, investigate buoyancy, demonstrate inertia, and discover the Bernoulli principle, which allows planes to fly. Plus, turn the bottle into a barometer, a thermometer, walkie-talkie, trombone, compass or groovy lava lamp. 79 experiments in all. Ages 9 and up. Paperback by Lynn Brunelle.
