Many people think that the so-called ice bucket can add ice, right? Because the temperature of ice cubes is definitely lower than that of water!

In fact, an ice bucket with only ice cubes is not enough. A very critical step is to add water, because the contact area between the ice cubes and the wine bottle is small, and there is a lot of air in the middle. Compared with water, the thermal conductivity of air is Very low, adding water will increase the contact area with the surface of the wine bottle, and also increase the thermal conductivity, so the cooling effect is better after adding water.
