i modified a small metal bubbler type piece, it has 2 litre chamber capacity but instead of chambering it like a bucket you chamber it like a bubbler, remove the stem and hit it like a bucket. Looks like a normal pipe but man it fucks you up. Only downfall is that the water doesn't force the smoke into your lungs, but honestly after you get used to hitting that thing, its not that difficult to clear the chamber. I love it, ease of a bubbler but fuckedupedness of a bucket. Ill post pics of it in use next tuesday when i am back home.
