Seeing is not always believing, and this book will challenge whether readers should believe their eyes. It contains all sorts of optical illusions including shadow play, magic mirrors, kaleidoscopes, visual vibrations, and more. Readers will be able to make patterns flicker, spin, and constantly change shape; create absurd faces in the funhouse mirrors; see beautiful abstract images through the kaleidoscope; and pull tabs and open flaps to reveal magical surprises. Plus, the book features a drawer full of additional pieces to create yet more illusions again and again.
