Smithsonian Discover: Flight" brings the awe-inspiring experience of the Smithsonian's National Air and Space Museum right into the pages of a book. It's a personal guide to the history and science of flight, and a collaboration with the venerable Smithsonian Institution. This authoritative guide answers all the questions that kids ask (and that parents may not be able to answer), like "What makes a plane stay in the air?, " "What's a sonic boom?, " and maybe most importantly, "How do astronauts go to the bathroom in space?" Arranged into three sections, Balloons in the Air, Machines in the Sky, and Starships in Space, "Smithsonian Discover: Flight" chronicles the history and evolution of flight in way meant to inspire future aviators and astronauts. This unique title also delivers hands-on activities like you would find at the Smithsonian. Bound right into the book are 12 fact cards on the coolest aircraft, a large double-sided poster, and 9 paper airplanes in three designs (a historic glider, a military jet, and a space shuttle) with easy-to-follow folding instructions. Altogether, "Smithsonian Discover: Flight" offers kids a chance to take off on a trip to the Smithsonian without ever leaving their seats.
