i love it when that happens. when i was staff at a summer camp in the staff canteen there was a pop machien and the temp was to low on it when you opened the bottle it turned the pop in to a slushie. there is nothin better when it is around the 40 celcius mark lolI have put bottle of a soft drink in the fridge to cool it and forgot about it. Hours later I took it out, and there was no ice in the bottle--until I opened it. Then the ice formed.
