For the first game we connected the glow sticks to make different sized circles which we taped onto the white board. We had some that were shaped like a bulls-eye and then some outlying ones. Each spot was worth a certain amount of points. We used Nerf guns with suction darts to shoot at the white board. Wherever the dart stuck is how many points they got.
For the second game we played glow in the dark bowling. We partially filled up some two liter bottles with water and stuck glow sticks inside of them. Then we used a large bouncy ball to bowl the pins over.
For treats we served glow in the dark drinks. I simply mixed lemonade, Sprite, and 2 crushed up Super Complex B vitamins and it really did glow under our black light. Something about the B vitamins makes it glow.
