Supose you take a can of soda/beer directly off the line, and shake it vigorously. Would it eventually reach an equilibrium, or the same state that it was in before shaking it? This is assuming no changes in pressure or temperature.
If shaking the can, say in a paint shaker, alters the contents conditions such that they cannot equalize, how could one return the contents to their original state?
Well, cold liquids can hold more dissolved gasses than cold ones, so the refrigeration thing would probably help. I doubt the can would contract enough to make much of a difference.
Hmm, along those lines, it seems that the device should work… increase of pressure would force the CO2(g) to dissolve… (Oh no, I’ve forgotten the name for this equillibrium law! something hyphenated and french…)
