Coffee anecdotes do you know that black coffee can predict the weather?
Suddenly it began to rain, and you ran to the door of a cafe to take shelter from the rain. Now there are only two ways in front of you, either run to the nearby bus stop immediately while the rain is not heavy, or go into the cafe and quietly order a cup of coffee until the sky clears up. OK, order a cup of coffee, throw in a cube of sugar, and observe the bubbles released by the dissolution of the cube sugar without stirring. If the bubbles gather in the center, the pressure is very high and the weather will clear up soon. The attachment of bubbles around the cup indicates that the air pressure is very low, either heavy rain or snow. The surface tension formed by the oil of coffee beans is the key factor to determine the position of bubbles. So instant coffee doesn't have this effect. "A cup of coffee knows the weather."
