Paintball Tracers with LEDs   (+3, -1)  [vote for, against]
Like flying traffic lights. With hurty-ness

Paintball-sized foam balls, the same mass as standard garden-variety welt-making devices. Contains 6 orthogonally-oriented leds powered by a small battery.

Mix them into your hoppers, but not until you pull the plastic interruptor out of each one you intend to use - thereby allowing the circuit to be completed and powering up the lights.

Not recommended for nighttime use if you have a clear paintball hopper - your gun will light up like a christmas tree. A christmas tree that wants to be shot.

Baked for a different sport ...
Reuseable, activated by impact. [batou, Nov 19 2007]

I thought about LED's, but I have an affinity to glowsticks from raves in my past.

Glow sticks are the way and then your enemy will be easier to hit again, but do people really play this in the dark?
