Need to launch hot dogs, brats, and other stadium snacks into the upper bleachers at your local ballpark? Then build a Burrito Blaster with John Park. Based on the classic combustion-powered “spud gun” project, this cannon instead relies on an air power. Made with everyday objects like a sprinkler solenoid, PVC, and simple circuitry, this project is great for picnics, games, and other outside fun.
