theres some video online of a few guys making a hookah out of something glass... a vodka bottle i think? iunno man.. but give that a shot. see what they do, and if youre not into hookahs, make your own bowl out of a sprocket and whatever you want for a downstem (prefferably not plastic though). and invest a buck or 2 in a good rubber grommet, because if youre making it, chances are the seal wont be tight. g'luck :thumbsup:
