Long before planes and rockets existed, humans dreamed of taking flight. Examine the science of aviation -- and try numerous experiments that prove all the theories. Using cardboard, a ruler, and other everyday items, learn how air currents work. "Twirly-Whirlies, " made out of pencils, cardboard, scissors, and thumbtacks, demonstrate how helicopter rotors operate. With an empty spool, discover the power of centrifugal force. And while you're having fun, you're effortlessly gaining a real understanding of Bernoulli's principle and Newton's law of gravity.
