In article , steamer says...

--The trick is to use an old, large soda bottle; i.e. a plastic
one with a large cap. Insert stuff to be carbonated, then toss in a few
hunks of dry ice. Cap the bottle and immerse it in a bath of ice water for
an hour or so. Don't know why (not a chemist) but CO-2 absorption goes way
faster if you drop the temperature.

If one puts too much dry ice in there, the bottle might
pop. When they do it sounds like an M80 going off, or
so I've been told.

Interestingly the solubility of CO2 seems to *reduce* if
the temperature is dropped enough. Somebody once attempted
to cool his warm bottle of coke by dipping it into an
open topped dewar of liquid nitrogen, when I was working
in boston.

All the CO2 comes out at once, the gyser of coke hit the
ten foot ceiling in the lab.
