Self-lighting Yo-yo

This yo-yo allows people who aren’t very good at throwing yo-yos to be engaged with the toy. It lights up as it is thrown, and can teach children about kinetic energy due to its self powered nature. As the child plays with it, it’s rotational energy will be converted into energy to power the lights.

The fact that it is self-powered means that it will last far longer than normal light-up toys, and the nature of the yo-yo allows for durability. It also should be fairly easy to replace any parts.
