I think what it means is like a bong with a seperate chamber attatched.I had one like that.The bowl or cone as we call it is attatched to the smaller chamber and the smoke has to pass through both and into your mouth.I think thats what it is anyway.Also if it is that kind you can remove the smaller chamber and just use it as a regular bong if the stem is the same size.
jacquelyne Reviewed by jacquelyne on . question about bong i was looking at some bongs today on grasscity and i came across this one bong referred to as a mini glass bong double conical tubing? i was just wondering though since it didnt say any details on it or anything how exactly does it work? im sure some of u people know what kind of bong i am talking about. it has 2 bowls. well do u smoke both bowls at the same time or something, or one after another? :confused: ? atleast thats what i assumed. let me know if i am wrong and if u could give me any Rating: 5
