Original Post from MAKE:


Make: Talk 020 – Air Rockets and Folding Wing Gliders. Rick Schertle is the creator of one of our most popular projects in MAKE: the compressed air rocket launcher, which uses PVC pipe and a sprinkler valve to blast a paper rocket high into the air. Rick is also the creator of the folding wing rocket glider, and most recently, he wrote a project that shows you how to make a catapult launcher that sends the rocket glider even higher. Mark Frauenfelder spoke to Rick about these projects and more. http://bit.ly/XG5viX
