Launch a rocket with just air and waterpower or make your own kite and add a parachute for extra pizzazz. Build an airship to fly or helicopter lifted by a balloon and much more. The sky s the limit! Have fun powering up tiny versions of real-life vehicles. Step-by step, child-friendly instructions are combined with cool illustrations to show you how to make each kind of craft safely. Each book has nine super projects, each with an explanation of the science behind them and a photograph of the finished result for guidance.
