akrivitsky16 (USA) Glow in the Dark Tennis Kit 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.
