haha, my gravity bong in my bathroom has a stem going down man lol and yes, it works well and it does filter the water quite nicley. and btw, with my idea, the density of the smoke is maintained because none of it comes out of the chamber until you want it to due to the fact that the water in the second bong acts as a seal. once you're raedy to tak the entire hit, just put your mouth up to the second bong and take it all in. like i said, the water seals it so no need to worry until you're ready to take the hit.
