i actually like his idea. what about like a gravity bong with a fitting for a joint on top, light the joint and keep taking gravity hits? or one time i broke a glass pipe so i cut a hole in a 20 oz bottle and stuck the bowl part in there and caulked it off, i goot bigger hits off that thing then anything else ever. you can use fruit, apple or orange banana. im in man lets get creative and build a bong.
