A hair-cutting machine, a used gum receptacle, jumping shoes, and more of the strangest inventions ever! A hat that can tip itself. A suitcase that turns into a bathtub. A pair of protective eyeglasses for chickens. These are just three of the hundreds of unusual inventions that people have dreamed up over the last two centuries. Some, such as the mustache guard, made perfect sense when they first appeared. Others were considered just plain silly. Jim Murphy has compiled a collection of the weirdest and wackiest inventions and presented them in a quiz style that is challenging and fun. Simple, clear explanations are provided on how the inventions worked or failed to work. Complete with over 100 colored illustrations of these crazy creations, this is the perfect gift for any child interested in science and inventions.
