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.

I've seen a few demos involving LN and water (the water only to vaporize
the LN faster); the two are put in a bottle (in one case it was a much
larger jug, with a cork stuck in it a _little_ too tightly... POW!), and
in the case of the pop bottle, dropped in a protective cylinder so as not
to throw, shall we say confetti, on the crowd.

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.

As a metalcaster, this sounds familiar...(I wonder just how much hydrogen
aluminum can hold?)
