Calling all future Amelia Earharts and Chuck Yeagers--there's more than one way to get off the ground The Flying Machine Book will show you how to construct 35 easy-to-build and fun-to-fly contraptions that can be used indoors or out. Better still, each of these rockets, gliders, boomerangs, launchers, and helicopters can be made for little or no cost using recycled materials. Rubber bands, paper clips, straws, plastic bottles, and index cards can all be transformed into amazing, gravity-defying flyers, from Bottle Rockets to Grape Bazookas, Plastic Zippers to Maple Key Helicopters.Each project contains a materials list and detailed step-by-step instructions with photos, as well as an explanation of the science behind the flyer. Use this information to modify and improve your designs, or explain to your teacher why throwing a paper airplane is a mini science lesson.
