Be a scientist--and a magician--all at once! With just a little practice, you'll amaze people with fool-the-eye illusions that look like science experiments. Make a poker chip glow with a ghostlike blur. Shine a flashlight so it leaves a trail of light. Draw shark fins in a book, then watch them swim. Make an X disappear from a piece of paper. Turn green boxes red, then green again. Try all 50 tricks!
Gr 4-6-Using common household or classroom materials, youngsters can complete more than 50 projects. DiSpezio begins with the scientific explanation of how and why the illusions work and includes general safety rules in handling the materials. Zweifel's line drawings are easy to understand. While there are more glitzy books on the subject, including others by the author, this one is practical and useful.

Gr. 3-6. DiSpezio offers 50 optical tricks to try, and explains the optical and scientific principles that make them work. Sections cover experiments based on motion, distortion, and depth. Some projects are simple constructions of coins, string, or paper; others are quite complicated, requiring lengthy preparation and special items such as colored cells or a motor from a mechanical toy. DiSpezio also includes activities that explore color afterimages and explain natural phenomena, such as why we sometimes see visual floaters. The conversational prose is fairly easy to follow, though some of the scientific explanations are challenging. Black-and-white pencil drawings--often featuring a cutesy frog and porcupine--are not particularly appealing, though they do add to the explanations. Despite the unattractive art, kids will find some easy illusions to amuse and surprise their friends. Includes safety tips.
