Slinging.org

The sling was likely mankind's first, true projectile weapon. It generally consists of two cords and a pouch. These cords are held in one hand and a projectile is placed in the pouch. The length of the sling provides greater mechanical advantage than one's arms.

The sling is unique in that the movement of the weapon is merely an extension of the user's body. The power and accuracy of the weapon is not by technological means, but rather user skill. The connection between slinger and sling is an intimate one, a relationship rarely found in modern weaponry.
