9Air Power makes rocket science as easy as blowing up a balloon and letting go. This book and science kit in one delivers rocket-propelled fun with four easy-to-assemble vehicles -- race a sturdy cardstock hot rod across the floor, glide a hovercraft over the dining table, take flight with a helicopter, and blast off with an only-from-Klutz balloon-powered rocket. Tweak, tinker, and experiment to make your balloon-powered craft go as fast as can be.
Our book contains super-clear building instructions, scientific principles, and real-world examples that make rocketry and jet propulsion simple. Air Power brings a breath -- make that a blast -- of fresh air to Sir Isaac Newton's famous Laws of Motion. It turns out that rocket science is way too much fun to leave to the rocket scientists.
