Physics question. Why's my Coke still frozen?

[carpetbagger]

I know this is probably more my laziness in figuring it out than my lack of knowledge of physics, but here goes...

Sometimes I put my Coke in the freezer to cool 'em down more and more quickly. Of course, when they freeze too much, they expand.

Is it my imagination that after the can expands, the pop remains frozen for an inordinate amount of time, more than you'd expect from just the fact that it gets completely frozen, or is there something to it?
