Nerf+Gun++Shootout

We will not be able to carry out Keith's idea (the one with two parts) as our stall is at the hall! Who plays basketball in the hall?

Thus, we are down to Nerf Guns. Why don't we just place pryamids of cans and ask them to shoot them down. Simple but fun! Increase the distance between the place to shoot from and the cans as the player's age increases. ~Giresh
