What should I do if the tea cup grate is not affected by the surface tension of water? It's just that when pouring water, the filter screen of the teacup (mine is the iron round hole) is not very good for pouring water. The greater the surface tension of water, the easier it is to form a water film. The surface tension of salt in spring water is the largest, followed by pure water, and most other water-soluble substances can reduce its surface tension. As for tea, milk tea and other high and low values, I don't know. Maybe I can try to find a substance that can quickly reduce the surface tension value, such as adding sucrose ester. In addition, the surface tension of water decreases by 0. 1.8mn/m every time the temperature rises by one degree.
