A slingshot  is normally a small hand-powered projectile weapon. The classic form consists of a Y-shaped frame held in the offhand (no dominant), with two natural-rubber strips attached to the uprights. The other ends of the strips lead back to a pocket that holds the projectile. The dominant hand grasps the pocket and draws it back to the desired extent to provide power for the projectile—up to a full span of the arm with sufficiently long bands.
