Kind of hard to explain but I was wondering what happens if you've just taken a lungful of smoke and then drank some water, held the water in your mouth, and then exhale the smoke. I watched a video of a guy taking a bong hit and then drinking a lil water. The smoke seemed a lot thicker when he exhaled and I was wondering if it was because of the water. Or maybe you do have to swallow the water? I would try it out tomorrow but I figured I might as well just ask on here. I've been meaning to try it for awhile.. Edit: the guy in the vid didn't drink the bongwater, btw.
