A toy capable of combined rotational and translational motion. Two parallel discs (3) are connected through their centers by a single axle (2). The axle is suspended from a support (35) connected at a position between the two discs. Said support (35) is of a twist-resistant type, offering a greater torsional resistance to twisting about the axis of the string than conventional yo-yo strings. The support (35) may be anchored to the axle (2) in a non-sleeping mode, or it may be looped around the axle (2) allowing the yo-yo to sleep. In order to operate the toy, the end of the support (35) opposite that which is connected to the yo-yo axle (2) is held by the user, and an up-and-down gentle motion is imparted to the toy. The end of the support (35) may be connected to a swivel system (40) which is in turn connected to a ring (41) for holding the toy. |
