According to the Daily Mail of London, it is easy to spill coffee on your clothes or burn your hands when you walk on the road, which is a big problem in modern life. In response, Korean scientists conducted theoretical analysis and experimental tests, and finally found that the crux of the problem lies in the wrong way people hold cups. Scientists say that people tend to hold the handle of a cup or the side of a paper coffee cup when serving coffee, which inadvertently intensifies the force on one side, making the liquid in the cup slosh more violently and increasing the chance of spillage
But of course, there is also a risk of scalding by steam. Fragile paper cups can also die under stress. So the researchers have a second secret: walk backwards.
