You make like...half a bong, right? You have a smoke chamber that's open at the bottom, and a bowl through a cork that plugs the top. You sink the chamber in water, plug the top and light the bowl. Then lift it out of water and the whole chamber --however big of a jug or whatever you use-- fills with smoke. Pull the cork, put your mouth on it, and shove it back down, pushing the pure smoke into yer lungs. Tada!
