Hello,

have a look at a glass of sparkling water or beer. When you observe it over a period of time and the initial heavy sparkling ceased you see a few stationary points, from which very tiny gas-bubbles evolve. Roughly 10 per second. I took a slomo-film with my IPhone 6 (240 fps). They raise up and grow in diamenter roughly by a factor of 2 per cm. Hydrostatic pressure release is only a few Pa, which should not be the reason.

If diamenter grows by a factor of 4, the volume grows by a factor of 60. How do the bubbles grow so rapidly in spite of the fact, that CO2 will have to diffuse against the concentration gradient.

Regards
