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 !
To make, cut a star shape from a piece of cardboard. Lay the stencil on the lawn and spray the grass lightly with water. Leave the stencil in place, and use a flour sifter to fill the shape with flour. Remove the stencil and repeat.
