glow sticks
Update
I am starting to think the glow juice may have been damaging after all. I hadnt used my gun in a while and i found that the threaded coupling at the end of the barrel was cracked down the whole length. I also knocked my clear barrel off a box about 2 feet in the air and it shattered. Maybe I'll find another way to shoot the stuff cause it is too good to stop doing.
