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.
