the posts are piling up quickly gain over here I see
what I use for connecting to a bong:
standard glass stem with thin silicon sleeve, for seal with 14 mm GonG, and a thick silicon bowl. I like to be able to remove the thick silicon bowl easily, so the length that it shares with the glass is so short it slides easily. the thin silicone sleeve is so long that, while making the seal, it will stop the thick silicon at the desired point(with 1-2 cm between the glass and the screen)
I used to reove the entire downstem with clearing, but now I just remove the UD+bowl, the bowl is just a short piece of thick silicone so it will hang onto the heatport, if I don''t take abother hit immediatly I remove it and ether put it away or leave it on the bong, the bowls will stand on their own, so I can have multiple partly vaped loads at once(hash and weed, or multiple strains)
also another funny story of UD-convertion.
last week a friend came over, who never really liked vaporiing. he used my VG multiple times, but never quite got the hang of it.
we sat down and took alternating hits with UD+bong, with hash. I already began feeling it, but he said he didn''t really feel it. so I emptied out my grinder, wich was 1 bowl worth, we vaped that. aftyer that continued with the hash, and I threw in some hash of myself to make it a little denser. at this point I began to feel pretty vaped, I asked him if he felt it now. barely he answered, about the same as from 2 hits from a joint(without tobacco, I converted him to smoking pure a while back).wich is weird, since he usually is higher sooner. since he had to leave soon I handed him the UD without bong, wich he liked better.
when he is about to leave he says he does feel it coming on then.
and today he says he wants to buy a vaporizer too(but one that is portable and electric)
