Written by Keith and Rick, our instructions are user tested by our families and friends. We go through the process described, step by step, and take photographs. If you run into problems or have questions, don’t hesitate to ask us…The collaborative process of rocket launcher building and rocket development requires close integration of technology and design – two disciplines that inform one another. The first version of this launcher was introduced to the world by back in 2008. Since then, individuals, groups, and Maker Faires all over the world have had a blast introducing rocketry to kids and adults with this launcher. Rocket building can be easily scaled up for larger groups at a very low cost, and many teachers have used our launchers for student design challenges. We’ve launched over 2000+ rockets in one weekend with one of these launchers!
