Description: You won't believe your eyes! How could you possibly be seeing a hole in your hand, solid objects that don't exist, or straight lines standing up and making a carpet fly? They're optical illusions -- images that trick and deceive you. To make any of the 101 projects shown here in full color, you just need ordinary materials like paper, glue, scissors, pencils, and a ruler. Yet with these simple things you can put a bird in a cage without touching it; break a spoon and put it back together without glue; make ghostly shapes appear and disappear; turn one picture into two; and make objects change color. Use magazine clippings or your own drawings to get a whale to swim, a kangaroo to jump, or a ballerina to dance. "Several different kinds of illusions (psychological illusions...physical illusions...perceptual illusions...) are explored in this large full-color volume that contains more than the 101 examples of the title. Jennings includes directions for making a number of demonstrations and optical toys....This is an attractive introduction to the subject". -- Kirkus.
