When people want to drink water, but the water is too hot, people like to use two methods to cool the water: one is to blow air into the water surface with their mouths; The second is to put water in two cups. It depends on the temperature of water in the glass at that time. Oral blowing is the fastest method, but it is only applicable to the situation that the water temperature is not very high and it is too hot to drink. You can pour two cups back and forth at this time. The best way to drink boiled water in a hurry is to find two large glasses. Don't pour too much water (the smaller the cup, the less water you should pour). After pouring into a cup, shake it horizontally. After the cup is ironed, pour it into another cup. The height difference between the two cups can be properly opened to facilitate heat dissipation in the air. Cool the empty cup in tap water, shake the cup with water according to the above method, and then pour it into the cooled cup. ............. repeats the above steps until the water can be safely and comfortably drunk.

The above methods are most suitable for drinking boiled water in a hurry. If not, the steps can be simplified. This method is extremely efficient, so try it!
