This is how washing machines sometimes work, but if there is a gas bubble =
at the top of the beer storage (from carbonation) then this won't work as =
well... the washing machines work because the open top guarantees the only =

It should be noted that this isn't something I've done, just a thought:

Sealed tube (aquarium air line?) which runs from the top down to
the bottom of the tank.  As the pressure of the beer increases, it'll
compress the tube, increasing the pressure inside the tube.  I
suppose it would only work if the top is open, but I was thinking that
it probably would be, so he can pour the beer in.  If not, it would
probably not work...
