i used a 20oz smart water bottle, a sharpie tube(rinsed out good), and a regular ball point pen tube, sorry i dont have my bowl on there right now but it goes on the end on the pen tube, i stuck the pen tube down into the sharpie but at first the seal was not good enough so i wraped some duck tape around the tube a couple of times, that created an air tight seal so i can still pull it out to clear the bong but its air tight so i dont loose any suction. i sealed around the sharpie with some duck tape that a slightly melted on there so its air tight and melted the side of the bottle a little so the sharpie stays upright.
Tell me if theres prob with the pics im having problems uploading them, so i put them on photobucket
