Slingshot

A slingshot, or wrist rocket, is a small handheld weapon that fires small projectiles. It is normally comprised of a cylindrical handle that splits into a fork. A taut, elastic band is stretched between the two ends with a catch pocket sewn into the center of the band. The projectile is placed in the catch pocket and the user draws the elastic band back as if it were a bow and arrow and then releases. The tension of the band snaps, sending the projectile flying at great speed towards it intended target. Generally, a slingshot does not do a lot of damage, but depending upon the object being projected, the tensile strength of the cord and the length by which it is drawn, it can cause a very serious welt.
