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.
