How much CO2 would vinegar+baking soda produce? I haven't heard it mentioned here, so I assume you'd get a burst of CO2, but not as much delivered over time as the yeast+sugar mix. Just curious.
Since I haven't seen it mentioned here, and aquarists are tinkers, I assume it's not really useable, unless you can trap it an regulate it. I was just curious if anybody has rigged a system to use this reaction.
