Yo-Yo is one of the toys that children of all ages generally like. This Yo-Yo is a storage lighting yo-yo designed for the play and learning of children in these poor areas. Children can play during the day. During the high-speed rotation of the yo-yo, the kinetic energy is converted into electric energy and accumulates. It can be used as a lighting at night, so that children do not need candles when they study at night, which saves resources and protects children's eyes. It also solves the problem of children learning and playing in poverty-stricken areas.
