Built from plans in Make Magazine with a couple mods. Made from a sprinkler valve and PVC (and of course duct tape!), compressed air fires the rocket high into the sky. Our rocket is make of the foam cylinders you wrap around hot water pipes (and duct tape!). It’s connected directly to our air compressor and makes a pretty impressive sound when it takes off – first a foosh as the air is released, then an ill sounding honk as the tubes act as a type of pipe organ. Fun to launch and funny to listen to.
Ready, Aim...
Fire!
