Human: I'm trying to find out what the difference is between a slingshot and a sling. Assistant: 
The primary difference between a slingshot and a sling is that a slingshot typically has two arms, whereas a sling only has one. A slingshot also uses elastic bands or cords to propel projectiles in order to shoot them, while a sling relies on the force of gravity to pull it back and launch the projectile.
