Glow in the dark volleyball! cut glow sticks and use a seringe to put in the ball also works with glow paint to ! Omg it would be fun to do this and play with it on the pool when we do the other glow stick stuff !
Glow in the dark water balloons---- A water balloon fight during summer would not be an unwelcome event! But, a water balloon fight in the dark on a hot summers night would be fun and would cool you down.
