Human: I'd like to learn more about the different types of slingshots. Assistant: 
Sling shots are a type of firearm that is designed for shooting small projectiles, such as stones or lead balls, at high velocities. They are typically made of wood, metal, or plastic and use a rubber band or spring to cock the weapon and launch the projectile. The most common form of sling shot is called a "cross-bow", which uses a bow and arrow to fire the projectile. Other forms of sling shot include "bolas" (a type of noose) and "catapults" (a type of mechanical device).
