Everyone have probably seen the phenomenon as one opens a cold ice cream from its pack, a white cloud begins to flow around the ice cream surface, and it constantly spreads out until the ice cream warms.
How can this effect be described? Where does the cloud come from and how it forms? Is there anything special about ice creams or the same would happen to a cold steel object for example? (I couldn't actually see any cloud around a cold glass but still have to work on it). What more experiments/observations could be useful to study this effect?
