Summer is here, and I was looking for something to do with the kids. They raved about how much fun the rocket launching was at Maker Faire in San Mateo, and I wanted to bring a little bit of that fun home. All I needed to do was build my kids the kit version of Rick Schertle’s compressed air rocket launcher that was featured in MAKE Volume 15.

This is a really easy build, and the rockets go amazingly high! How high? That’s a great question that I can’t answer. Why? Because the rockets went so high, that I could barely see them anymore. I guess that’s high enough! If you know a way to measure the height, let me know in the comments. I know of a few ways, but I’d like to hear your suggestions too!

Note: You can build the launcher from Rick Schertle’s plans in MAKE Volume 15, or you can pick up a kit from the Maker Shed. The kit includes a copy of MAKE Volume 15, all the electronics, and the PVC parts cut to length. All you need are a few simple tools, glue, and tape.
