Brain Wizardry: With More Than 50 Mind Bogglers, Optical Inventions, Magic Tricks, and Visual Illusions

Filled with flaps, pop-ups, this collection of brain-teasing activities contains optical illusions, magic tricks, and puzzles that illustrate how the mind and senses interpret (and misinterpret) information. Visual highlights include printed text stretched vertically that becomes legible when the book is looked at from an angle, a Möbius strip that seems to move, and orange dots that trick the eye into seeing movement; also included are a paper model of a camera obscura, 3-D glasses, and a model zoetrope. The tangible effects of each experiment should intrigue readers. Ages 10–up. (Oct.)
