Why does a can that has boiling water get crushed when it is stuck in cold water in a sink?

A can containing a small amount of boiling water is filled with water vapor and very little or no air. When cooled quickly, the water vapor condenses into a few drops of water, leaving a partial vacuum in the can. Air cannot enter the can thru the small opening fast enough to equalize the internal pressure with the external atmospheric pressure, and it is crushed by atmospheric pressure.
