Potato Launcher

For the A.M. Makerspace interim, Miles, Liam, Peter, and I decided to make a potato cannon. We used a PVC tube, a grill ignitor, and hairspray. Once we glued the PVC tube together, Liam and peter drilled a hole at the bigger tube where the hairspray would go. Next we glued onto the grill ignitor and tested if we could see a spark. A spark was not made, so we found out that we had to ground the spark. We put a nail into the ignition chamber and tied a wire which ran into the ground. Then we tested if it worked, it didn’t. Next we took out the nail and connected a wired into the grill igniter, which created a much bigger spark. The launcher needed a hole to put hairspray in we drilled a hole next to the ignition, big enough to fit a cork into it. Then we tested it, and it didn’t work, but it did light a tablecloth on fire, and it made a big boom but it didn’t fire the apple.
