More and more middle and old age people like playing badminton on the square after meal. Sometimes, it is difficult
for them to recognize the ball due to lack of light. Add energy-transferable material at the bottom of the badminton,
kinetic energy transfer into luminous energy when hitting, so you are able to see the ball after dusk.
