It is very hot in summer. Xiaoming took out a bottle of cold drink from the refrigerator and put it on the glass coffee table. After a while, Xiao Ming found a bottle outside.

Answer: the drinks taken out of the refrigerator and freezer are placed on the glass coffee table, and the glass temperature of the coffee table drops. When the water vapor in the air meets the glass of the low-temperature beverage bottle and coffee table, it liquefies into small water droplets, which adhere to the outside of the tea beverage bottle and under the glass of the coffee table, so small water droplets appear under the coffee table.
