it may break the glowing thing in there on landing and launch so i wont be able to find it in the dark.
Landing... no. It'll return to the ground by force of gravity only, and because of it's drag, GB's don't have a very high terminal velocity.
Launch, that depends, however, things will survive a more violent acceleration from an air cannon than they would from a golf club, because the force from a spudgun is spread equally across the surface of the projectile, which prevents the same stresses as a golf club.
I think it'll survive.
