The Rolly-Polly discs, are designed to set up a hockey frame using a broken stick handle. The feature of this frame is due to the displaced center of mass of the disk, the frame always returns to its working position, no matter how you hit it or throw it on the ice. This saves time for both the hockey player and the coach, because there is no need to bend down and put the frame in the working position.
