Kids will love to fold and fly these sturdy, aerodynamic paper airplanes!In this clever origami book with folding papers, paper airplane expert Andrew Dewar presents his ultimate collection of easy-to-fold, high-performance planes for kids who are fascinated by aviation, technology, or origami. These planes are brightly colored and designed to fly beautifully every time. The book opens with a fascinating introduction to the engineering principles of flight, so kids can learn about the forces that enable a plane to fly and affect the performance of their airplane designs. They'll have fun putting the paper planes through their paces: doing loops, barrel rolls, glides and dives. The sky is the limit once they understand how planes interact with the atmosphere!
