Not to belabor the "other thread", but this is the major thing that
leads me to believe that the CO2 mist is not CO2. CO2 dissolves very
quickly. Why would it suddenly stop when the surface area is larger? It
seems reasonable that the other gases are diffusing into the bubble
while the CO2 is exiting. By the time the CO2 is essentially out, there
is enough O2 and N2 to leave a small bubble.
We know for sure that other gases will diffuse into the CO2 bubble, but
what we haven't measured yet is whether that diffusion is sufficient to
explain the persistent little bubble.
