Abstract
A yo-yo includes an outer ring, a support arm extending inwardly from the outer ring and a disc supported within the outer ring by the support arm. In addition, a region on the outer ring adjacent the support arm is thinner then another region on the outer ring opposite the support arm to compensate for any additional weight defined by the support arm. Furthermore, the outer ring is defined as having a cavity and the disc has an overall shape smaller then the cavity such that the disc appears to be suspended within the outer ring.
