<p>A toy according to the invention includes a substantially linear rigid grip to which two spacers are hinged, each one of the spacers being provided with a small ball at an equal and constant distance from the grip and rotating around the grip in such a way that the two small balls rotate around the grip. Each spacer is provided with stop elements suited to limit the rotation of the spacers, to transfer the quantity of motion to the other spacer and to prevent contact between the two small balls. Support elements are provided for the application or insertion of a cardboard element aligned with the rotation axis of the spacers.</p> |
