Here are the steps to make a potato gun:
1. Assemble your potato gun using a 3 in (7.6 cm) wide PVC pipe (14 inches (36 cm) long) as the main chamber. Attach a 4 ft (1.2 m) long 1.5 in (3.8 cm) wide PVC pipe to the chamber using a coupler and reducer to form the barrel. Install a spark generator or BBQ ignition switch to the chamber to make the trigger.
2. Cut a PVC pipe so that it's 4 inches wide and 2 feet long, and another pipe so that it's 2 inches wide and 5 feet long. Next, glue a female adapter to 1 end of the 4 inch pipe and a coupler to the other end as you prepare the launcher.
3. Pull the plunger of the syringe to maximum length without disconnecting the two pieces. Hold the barrel about a cm away from the open end. Stab the end into the potato a cm deep. Twist the barrel inside the potato so that the piece breaks off. Pull the barrel out of the potato and point at whatever you want to shoot at.
4. Shoot Your Potato Gun!
