Cooling your Food & Drinks in an empty refrigerator
You may notice that it takes a while for your food and beverages to "get cold" when you first put them in the empty refrigerator. Why doesn't this phenomenon happen at home? Your home refrigerator likely already has a good bit of cold items in it and those cold things help cool down the new room-temperature items you add to it! But, when you start with an empty fridge and add non-cooled items to it, it will take hours to cool them down to the desired temperature.
