The experiments in this collection seek to help children to understand the science of aviation while they have fun. Whilst making paper aeroplanes, gliders and kites, they also learn about centrifugal force, how air currents work and how helicopter rotors operate.

Long before planes existed, humans dreamed of flying. Examine the science and test the theories behind aviation, using everyday objects like cardboard, scissors, empty spools, and a ruler. See how air currents work, make "Twirly-Whirlies" that demonstrate how helicopter rotors operate, and discover the power of centrifugal force. Create paper airplanes, gliders, and kites. While you're having fun, you're gaining a real understanding of Bernoulli's principle and Newton's law of gravity. 128 pages, 75 b/w illus., 5 3/8 x 8 1/4.
