Rubber band guns are simple to make and can shoot a rubber band more than 10 feet, depending on the elasticity of the band. They work better than using just your fingers and can be made in less than 10 minutes. Because they are small, they can be easily carried in a pocket. Rubber band guns have just a few parts to them, and the pieces can usually be found around the house or in a craft or home improvement store.
Cut your wooden dowel with the saw so that it is roughly 12 inches long. You can make it shorter if you would prefer more of a pistol, or longer for a rifle. Twelve inches will fit the majority of rubber bands, while smaller guns need smaller rubber bands and larger guns need large rubber bands. Cut a small notch on one end of the dowel.
Glue the clothespin to the dowel opposite of the end with the notch and flush with the end of the dowel. The pinching end should face the centre of the dowel. This will act as the gun's "trigger."
Allow the glue to dry completely before using the gun.
Put one end of the rubber band in the notch and stretch it until you can grip the other end in the clothespin.
Point the gun at your target and squeeze the clothespin to shoot the rubber band.
For a gun that can shoot several rubber bands consecutively, use a thicker diameter dowel and glue three clothespins to the dowel; one on top and one on either side. Cut a piece of wood in a size that easily fits in your hand like a handle. Drill a hole and insert the end of the dowel into the hole. Make the rest of the gun as above. The handle gives you a little more control when holding the gun.
