This is my version of a Gravity Bong. Its an arizona jug wit the bottom cut off. I use a downstem for the bowl piece. Works very well, i may just get a milkshot up later the handle is very helpful for pulling it up. The bottom of the water container also has a drain piece (meant for iced tea) which is helpful when that water gets filthy. Happy toking!
i have almost made the same piece. replace the arizona tea with those hawaiian punch and a wrench socket instead of a bowl piece. work just as good as any other.
I have a similar setup with a gallon fruit punch jug. I bought the fruit punch for a party, and it hit me. Now I use a GonG downstem and bowl in mine, haha.
