i came up with the same at work today. i was trying to think "what will funnel these balls" and the obvious choice may be the best one. A blowgun mouth piece crossed my mind but i dont think the funnel will be deep enough. ill try and get to the store over the weekend and ill let you know what i come up with. i hope its as simple as it sounds. i doubt these hard little balls will break on anything but mask/gun/hopper but we all know thats where most of the hits will happen. if i can get 1 kill with it, ill smile all day.
