Re: Does Coke fizz in space?

Free  liquid itself forms into small drops held by surface tension, while 
the gas would still escape from high pressure into low pressure- out 
through the breach in the can lid. The gas woould escope out of the opened 
tin but since there is no gravity  the effect would be a considerable 
thrust on the can and some  propusion on the astronaut holding the can. 
This would not be a desirable situation in a space craft, and so not 
surprisingly has not been tried! Astronauts usually take non fizzy drinks 
from sachets through straws to avoid floating collections of liquid 
appearing all over the interior of the craft !
