That's one of the reasons I made it like that. The current version gives off no light when held, it's made to seem like you have to remove the cap for it to glow. And you aren't really meant to remove the caps of the old style glowstick.
So, this pic shows the glowstick being thrown, going from non-glowing to glowing, showing a little breaking puff of particles, and dropping the back cap. Makes more sense to look at the image.
