Things You'll Need
Instructions
Cut six PVC pipes into 3-inch pieces and one pipe at 7 inches. Join the elbow joint, 3-inch pipe, T-joint and another 3-inch pipe all together. Set aside. Join a T-joint and a 7-inch pipe together and then connect to the pieces. These pieces will automatically stick together, no need for any gluing.
To create handles to hold the gun, join a 3-inch pipe with second elbow joint that was put together. Put an end cap on each of the 3-inch pipes to avoid marshmallows falling from the holes.
To create the "shooter," join a 3-inch pipe to the first T-joint. Join this together with an elbow joint and another 3-inch pipe on the other end.
Place a marshmallow into the "shooter," hold the gun by the handles and aim where you want the marshmallow to land. Blow hard into the "shooter," and it will force the marshmallow out and near its destination.
