How to Make a Double Barrel Spud Guns

Potato launchers are guns made of PVC that fire potatos as projectiles.

A spud gun, also known as a potato launcher, is a device made of PVC that fires potatoes using aerosol as the combustible. These contraptions are simple devices composed of PVC pipe, a twist-off cap to fill the chamber with aerosol and an igniting device. A double barrel spud gun is the same device as a single barrel, but with a simple modification. Rather than a single potato projectile, a double barrel can fire two simultaneously. After purchasing the parts, building a double barrel spud gun takes less than 20 minutes.

Things You'll Need

• 10-feet of 2-inch PVC pipe
• Pipe saw
• 2-inch tee
• 2 2-inch elbows
• 3 2-inch couplers
• PVC primer
• PVC glue

Instructions

1. Cut 24-inches off the 10-foot stick of PVC. Cut that length into three 8-inch sections. Primer one end of each of the sections as well as the three holes of the tee. Glue one section in each hole. Lay the tee flat on your workbench. Primer and glue the elbows to the arms of the tee with the holes pointed in the opposite direction as the hole in the leg of the tee.

2. Cut the remaining 8-feet of your PVC stick in half. Primer and glue the two 48-inch lengths to the elbows attached to the tee. Glue the reducer to the leg of the tee. Glue the 24-inches of 4-inch PVC pipe to the reducer. Glue the adapter to the other end of the pipe.

3. Drill a hole in the center of the 24-inch length of 4-inch. Install the flint ignition in the hole according to its installation instructions and components. File the inside edge of the two barrels round.
