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 principal - which allows planes to fly. Plus turn the bottle into a barometer, a thermometer, walkie-talkie, trombone, compass - or groovy lava lamp.
