About this title:
A collection of over 80 tricks, silly stunts and brain-busting puzzles, all created in the name of science by puzzler and mathematician Martin Gardner. Features include: putting matches in a bottle of water and watching them sink or rise; commanding an eggshell to turn a somersault; keeping a balloon inflated with its "mouth" open; and lighting one match with the wrong end of another without touching it. The book is designed to help readers learn about basic science in water, air, fire, heat, gravity, motion and inertia, friction, magnetism, electricity, sound, light, sensory illusions and probability. Parental assistance is indicated by a symbol wherever it is required.
