no i understand what he's saying i think, i think he wants to resonate a bud like you would if you were to put it in a metal pipe. and idea that might work but would take extremely long since there isn't much left to the smoke after you initally exhale it. what you sould do if you have your heart stuck on this, is get a 2 liter, put alot of very small holes at the bottom, throw a nug in the bottom and start smoking, exhale ever hit into that and maybe JUST maybe after smokeing 6 or 7 grams of really good weed it might add something to the nug
