Abstract

This device is used to practice pitching form in baseball. When you grip the grip and swing the device, centrifugal force causes the tip of the stick to extend as you accelerate, and then the internal spring pulls it back. The sound of the parts colliding as they return allows you to confirm whether you are releasing the ball forcefully at the desired position.
