take an empty plastic pop/pill/whatever bottle and a small plastic tube(like the size that comes with your WD-40,etc.). drill a small hole in the bottom center of the bottle and the center of the cap,just big enuf to push the small plastic tube thru the bottle leaving a 1/4' or so exposed on both ends. super glue the tube to the cap end but leave the other end loose(it should be a tight fit and will be in the air most of the time anyway. you could put glowsticks in it and change them without rerigging. just a thought!
