How to play without a jam?

The sinker slingshot doesn't catch the ball, so it can be used as a small round object.

A kind of modern slingshot refers to a slingshot that uses steel balls with a diameter of 4.5 mm to 5.5 mm to fix a tubular rubber band in the bow eye ... and changes the traditional uncontrollable movable rubber band into a fixed controllable positioning rubber band. In this way, the instability in the launching process is reduced and the launching trajectory is regular. Therefore, the accuracy of slingshot shooting is greatly increased, thus rapidly improving performance.
