Well, I figured that eventually the co2 would "burp" as the bell fills, and realized this was inefficent, but then I confused myself by wondering why comercial bells were available (if it's not that great then why buy one?).
I've looked at one solution that tries to trap the co2 in the intake of a power head but I don't have the parts for that. I've seen the chopstick method too but I worry about it clogging. I haven't seen much else beyond that, well, that is as easy as a plastic bottle bell.
