This fascinating book will not only explain the basic forces at work behind different forms of transport, but will also give children hours of learning fun. Each concept is clearly demonstrated by a hands-on, step-by-step project that is easy to follow. Make a hot air balloon, a model catamaran or a railroad track and, through practical experiments, learn how they work. Take a look inside a car engine and discover pistons and crankshafts, then create artificial gravity with the aid of a centrifuge. With over 40 practical and well explained projects, learning how vehicles work has never been easier or more fun.
