Publisher's Note Cool distortions, a perplexing parallel pattern, afterimages, 3-D foolery, a shady comparison, imaginary interference, flip-flopping faces, and other optical illusions will "trick" you into seeing what isn't there! There's one thing you can be sure of, when it comes to optical illusions: appearances are always deceiving! "You won't believe your eyes, and perhaps you shouldn't. Once you read this book, you'll understand how your perception can be skewed...Page after page of illusions will have you reaching for a ruler to see if lines really are the same length or if the sides of that square are straight or bowed. Author DiSpezio presents many classics...as well as some less familiar ones. There are even directions on how to make some of your own magic...you won't want to miss any of these visual tricks.--Scientific American. "...presents a wide selection of illusions accompanied by clearly stated explanations...More complete and informative than most children's books on the subject, this entertaining, enlightening volume will be helpful for projects and fun for browsing."--Booklist.
