In this video, we learn how to quickly make a potato gun. You will need: 3" end plug with screw cap, 3" PVC pipe, 1 1/2" PVC pipe, saw, sandpaper, hammer, wire, BBQ lighter, and power drill. To start, you will need to use sandpaper to sand down the edges of the pipes so they all connect together. Place the screw cap on the pipes and then use the drill to connect the pipes together into glue form. Use a hammer to hammer in nails to the connecting pieces, then when you are finished you can use this to shoot out potatoes, enjoy!
