Hey guys and gals.. I am making this small bong/waterpipe out of a Bawls bottle (Guarana energy drink in a blue glass bottle) and I want to buy a real stem and bowl for it, instead of making some crappy metal stem. I'm looking all over GC and cant find any spare parts like this. Well, the Magic Glass section has some, but I just don't like 'em.. plus I would like to know sizes and whatnot. Can some of you help me out? thanks a lot guys.
