In the cold winter,Taking a bottle of boiled water in hands can make your hands warm but the water boiled a moment ago is so hot that you can not touch the cup. The water being exposed in air will turn cold soon.Now you can use the natural heat to cover the cup and put your hands in it.thus not only keeping the water warm but also avoiding to burn hands with the natural heat.how wonderful it is.
