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?
