Optical illusions are tricks your brain plays on your eyes. The ones in this book move around, jump up and down, float and spin, curve, twist, and leap at you - or at least they seem to. The book provides instructions on a range of magic tricks, puzzles and toys, ranging from making your finger float and putting a whole in your hand to making moving pictures out of still ones.
I got this book recently for a friends kids (twelve years old) birthday present. It got a casual thank you and put aside for the other action toys, video games and the like. About 2 weeks ago my friend rang me and said that his son had picked up the book, started to read it and was hooked, he is right into the book now. He is building the toys in the book himself (with his dads help) and has the hang of it so much he even attempted to create his own optical illusions.
