If you don’t have access to an air compressor or air tank with a spray-nozzle, you can either make your own rocket launcher (watch second video below), or make the blow-gun rockets. Either way, you’re going to be launching sky-high in no time!
- Two straws each in two different sizes
- two sheets
- index cards
- hot glue gun
- air compressor or air tank with spray-nozzle
- metal tubing that fits just inside the larger straws
