I don't believe I've had the pleasure. Sounds awesome though. Thats the kind of feeling I want when getting my smoke on.
My buddy use to make a gravity bong out of like a 2 or 3 liter plastic bottle and that shit would hit like a champ. But I have never done that with the quality of bud I smoke these days. But that was fun back in the day. Back then we couldn't roll blunts so we would empty out black and milds and stuff them with bud and smoke them. Man that was a long time ago, I think I was 15?
