Video of the Day
Assemble the mouthpiece by connecting the 9-inch pipe to an elbow. Connect the elbow to a 5-inch section of PVC, connecting that to a tee.
Make the hopper by attaching a cap to the 8-inch pipe. Attach a tee to the other end, and finish by attaching a 5 inch section of PVC to the tee.
Construct the handle by attaching 2 5-inch pieces of PVC to an elbow, placing a cap on one piece. The piece without a cap should be stuffed with cotton balls. The capped piece will remain empty to fill with extra ammo, i.e., marshmallows.
Combine all the parts together, attaching the 11-inch PVC section to make the gun barrel.
Use the gun by first loading the hopper with mini marshmallows and reattach the hopper to the gun. Aim towards a safe target and blow through the mouthpiece. When all is functioning well, all of the marshmallows should leave the barrel and the gun should shoot about 20 yards.
