We'll show you step by step how to build a two-stage system - a true feat of engineering that you can do at home. The difference? An ingenious mechanism that allows the stages to separate during flight, exactly like the legendary Saturn V, the Apollo program rocket that took man to the Moon! This is a new feature that will revolutionize the OBA rocket launch competition, and in this video you'll learn how to build your own.
