If you've ever wondered how an Etch A Sketch writes on its gray screen, or why a boomerang comes back, or how an R/C car responds to a radio controller, now you'll have your answers. The Way Toys Work explains the technology, history, and trivia behind 50 popular toys, with patent blueprints and photos of the &“guts&” of devices including: * Kaleidoscope * Magna Doodle * Slinky * Nintendo * Super Soaker * Big Mouth Billy Bass * Rubik's Cube * Silly Putty * Video Game Light Gun * Furby * Dunking Bird * View-Master * Yo-Yo * Push 'n' Go Car * Wiffle Ball * Gyroscope * Operation * Hula Hoop 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.

More frisbees are sold each year than baseballs, basketballs and footballs combined. Yet these familiar flying objects have subtle and clever aerodynamic and gyrodynamic properties which are only recently being documented by wind tunnel and other studies. In common with other rotating bodies discussed in this readily accessible book, they are typically not treated in textbooks of aeronautics and the literature is scattered in a variety of places. This book develops the theme of disc-wings and spinning aerospace vehicles in parallel. Since many of the examples are recreational, anyone who enjoys these activities will likely find it profitable and enjoyable. In addition to spinning objects of various shapes, several exotic manned aircraft with disc planforms have been proposed and a prototypes built – these include a Nazi ‘secret weapon’ and the De Havilland Avrocar, also discussed in the book. Boomerangs represent another category of spinning aerodynamic body whose behavior can only be understood by coupling aerodynamics with gyrodynamics. The narrative, supported by equations and graphs, explains how the shape and throw of a boomerang relates to its trajectory. The natural world presents still other examples, namely the samaras or ‘seed-wings’ of many tree species, which autorotate during their descent, like a helicopter whose engine has failed. The flight performance of these spinning wings directly affects the dispersal and thus the evolutionary competitiveness of the trees concerned. Samara-type configurations are also considered for instrumentation and other payload dispersal applications. In short, the book discusses a range of familiar, connected, but largely undeveloped, topics in an accessible, but complete, manner. From the reviews of the first edition: "In his fascinating book Spinning Flight, Ralph Lorenz provides a rich feast of ... examples of spinning bodies ... . The book is well organized ... . The discussion in the book ... should be accessible to readers with some elementary understanding of aerodynamic principles. For the expert, the book is full of open problems ... . Its scope is extensive ... . In this respect, there may be something for everyone within its attractively designed cover ... ." (H. K. Moffatt, Nature, Vol. 444, December, 2006) "If you liked physics at school, then this book is for you. It concerns itself with flying objects that spin through the air, and even tells you how to impress your friends with the biomechanics of Frisbees. ... there is plenty of information at all levels, and the book has a wealth of detail that only an aerospace engineer like Lorenz could have come up with." (Len Fisher, BBC Focus, February, 2007)
