The Little Giant Book of Optical Tricks

Welcome to the magical world of optical illusions. This is a book that will put you to the test to see if you can believe your own eyes. What you see is not what you get! What do your see - two ducks or two rabbits? Is that balloon really spinning? Try rotating the page! See a bird that seems to "fly" into a cage! A boy that turns into a monkey when you turn the page upside down! Nothing is what it seems, and first impressions are just that - impressions, not the truth. Luckily all the answers are the back of the book!
