So you're hitting some tennis balls with a good friend, when suddenly the sun goes down and you're seemingly out of luck. (court doesn't have lights) My invention keeps the night alive with a few glow in the dark components.
*Glow in the Dark Line Tape (makes court lines glow and can be applied to racquets for swing visibility)
*Glowing Tennis Balls
*Glow in the Dark racquet strings

Reward: One Glow in the Dark Tennis Kit and an honorable mention.
