If you've ever wondered how an Etch A Sketch writes on its gray screen, or why a moomerang comes back, or how an R/C car responds to a radio controller, how you'll have your answers. The Way Toys Work explains the technology, history, and trivia behind 50 popular toys, with patent drawings and photos of the "guts" of devices.

You'll also find pointers on how to build your own versions using recycled materials and a little ingenuity, experiments that can be done with certain toys, and tips on reverse engineering old toys to get a better look at their interior mechanics. The only thing you won't learn is how the Magic 8 Ball is able to predict the future - some things are best left a mystery.
