ya i just made a waterfall bong today...i used an old glass pop bottle that had the old metal caps on them...drilled a whole in the bottom of the bottle and then used a rounded hammer to indent the metal cap. followed that by drilling some holds in the cap with a small drill bit and tested it out. worked like a charm.

thats my two cents.
