As long as the downpipe goes into the bong water the slide should be fine any length.
maxsuperdanks Reviewed by maxsuperdanks on . bong question I have this bong I got from a friend for free. Only deal is, I didn't get a slider with it. So I rigged up some paper and a chillum and went to town. Recently I've been looking into buying a new slider but notice all the measurements and such on the ads. What do I need to measure on my bong or how do I tell what size of a slider I need? Rating: 5
