Don´t believe your eyes! This book is packed with strange illusions, mind-bending phenomena... and awesome science. Watch in amazement as straight lines bend, patterns spin, and pictures mysteriously ´flip´ from one shape to another. Then marvel at what each pattern reveals about your brain and senses! Ideal for children aged 7 and up. Each illusion is explained in terms that are clear and easy to understand. Every illusion is dramatic and immediately accessible, functioning as a hook that draws readers into the text. This is a great book for reluctant readers and visual learners.
