Slingshot

A slingshot or slingshut (primarily American), hand catapult (primarily British English), shanghai or ging (primarily Australian and New Zealand), kattie (in South Africa), bean shooter, or flip or tirador (primarily Tagalog), is normally a small hand-powered projectile weapon. The classic form consists of a Y-shaped frame held in the off hand, 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.
