Make an eggshell turn a somersault, spin a coin so that it lands on 'heads,' teach a bear to climb a string, and perform other acts of scientific wizardry! Martin Gardner, the master of mathematical puzzles, shares more than 80 of his finest magic tricks, teaching children and adults the scientific properties behind water, air, fire, heat, motion, gravity, inertia, friction, electricity, magnetism, sound, and light.Fun and fascinating, the simple maneuvers require only basic everyday props, and those requiring matches, knives, boiling water, and other tricky items are marked with a symbol that lets kids know they'll need assistance from an adult. Helpful drawings illustrate each stunt.
