Abstract
A toy capable of combined rotational motion about an axle and translational motion in a vertical direction. Two parallel discs are connected through their centers and are maintained in a spaced-apart position, by an axle. The axle is non-circular in cross-section, and is supported by a tape which is inserted along the axle's longitudinal axis between the two axle-halves. The opposite end of the tape may be attached to a swivel which is in turn connected to a holding apparatus. In order to operate the toy, the end of the tape or the holding apparatus is held in the operator's hand and a down-and-up motion is imparted to the toy. The body of the yo-yo may alternatively be suspended from a string which is firmly anchored to the axle.
