ABSTRACT:
The invention is a yo-yo in which at least one of the yo-yo's sides includes a powered rotation system capable of maintaining the yo-yo's rotation when the yo-yo is sleeping at the end of its tether. The system functions by converting one of the yo-yo's sides into a motor, and includes a number of permanent magnets, an electromagnet, a sensor capable of detecting a magnet field, and a power source.
