| A yo-yo is a toy that has two equally sized and weighted discs of plastic, wood, or metal, that are connected with an axle. Around this axle is a string that is wound. Yo-yo’s first became popular in the 1920s, and is still enjoyed by a large following of children as well as adults. Yomega is best known for its automatically returning yo-yo. The Brain available on this shelf uses a centripetal clutch mechanism which activates when the spin of the yo-yo gets slower. It then freezes the yoyo's transaxle and causing the string to wrap within the string-gap, and the yo-yo to return. |
