Abstract
A toy capable of combined rotational motion about a horizontal axis and translational motion in a vertical direction. Two parallel discs are connected through their centers by a single axle. The axle is supported from a string connected at a position between the two discs. The string is connected to one end of a tape. A swivel system is attached to the other end of the tape, and a ring for holding the toy is attached to the swivel system. The string may be anchored to the axle in a non-sleeping mode, or it may be looped around the axle allowing the yo-yo to sleep. In order to operate the toy, the user's finger is placed in the ring and an up-and-down motion is initiated.
