I don't see how the chinese made glass styles for instance would be any good. A big funnel reducing down to a pinhole at the bend before opening back up for the ph solution chamber can't be effective.
I'm not positive about this, but I think that air will exchange gases very easily that it's not a problem. Meaning whatever level of CO2 is in the bottom chamber will quickly equalize with the rest of the trapped air, despite the small opening. Like I said, I'm not positive, but I thought I remember something like that from a science class along time ago.
