Can a single card slingshot be loaded with heavy rubber bands?

A single card slingshot can hold heavy rubber bands. Slingshot became popular in 1970s and 1980s. Slingshot is a cold weapon or a game tool. Slingshot is generally composed of bow, rubber band and leather bag. It is usually made of branches and shaped like Aya. Upper belts are tied at both ends, and a piece of skin wrapped with projectiles is tied in the middle of the rubber band. The strength of the slingshot depends on the tension and rebound speed of the rubber band. The greater the tension of the rubber band, the heavier the projectile that can be matched, and the faster the rebound speed of the rubber band, which can provide a larger initial velocity for the projectile. The heavier the projectile, the higher the muzzle velocity and the greater the power. According to the launching mechanism, slingshots can be divided into bow slingshots and elastic slingshots. Bow slingshot has the most primitive bow slingshot and crossbow.
