Abstract
A toy capable of combined rotational and translational motion. 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. Said string 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 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 end of the string opposite that which is connected to the yo-yo axle is held by the user, and an up-and-down gentle motion is imparted to the toy.
