Now all I need is some weed to test 'em with.. the bowl is interchangeable. I took two plastic caps and cut holes through 'em, and tapes them together, and taped a socket that fit perfectly into them onto it. I can't wait to test 'em. :thumbsup:


A question, though: what's the principle behind a waterfall bong? Can someone please explain to me how they work?
