Book Description: "T-minus ten . . . nine . . . eight . . ." the countdown begins. Anticipation swells. The crowd holds their breath. The engines roar to life, and the massive rocket slowly rises from the vapor on the launch pad, defying gravity as it disappears into the sky. Fortunately, you don't have to be a rocket scientist to understand the dynamics and engineering behind these amazing machines. In Master Engineer: Rockets, kids learn how the fastest, most powerful vehicles on (and off!) the earth get their power, and how engineers continue to defy gravity with rockets. Packed with awesome action photographs, helpful diagrams and text, and a build-it-yourself model of a giant (five-feet, three-inches tall!) model of a Saturn V rocket, this book really ignites the imagination. In fact, it's a blast!
