 Slingshots are also occasionally used in angling to disperse bait into the water over a wide area, so that multiple fish are attracted near the angler's fishing rod.A home-made derivative of a slingshot also exists, consisting of a rubber balloon cut in half and tied to a tubular object such as the neck of a plastic bottle, or a small pipe.The projectile is inserted through the tube and into the cut balloon, and the user stretches the balloon to launch the projectile.
