Given a can of coke in outer space, say in a space shuttle or a space lab in zero gravity conditions, does coke fizz? I understand that the CO2 is held in the coke on earth due to pressure in the can keeping the CO2 in the liquid. When the can is opened, we observe the fizz rising as CO2 escapes due to the atmospheric pressure. But, naturally, the CO2 escapes by forming bubbles that flow up to escape the liquid. If there is no gravity, does the carbonation remain trapped in the liquid, does it escape all at once? With no gravity which direction do the bubbles go, or is there no fizz? This may sound odd, and I know it is a silly question; but, it's been bugging me for years. Anybody care to volunteer to go up and find out?
