Want to walk like flying coffee without spilling it? Scientists teach exclusive secrets
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. Jiwon Han, a researcher at the Korean Minjok Leadership Academy, said: "By reversing, we can greatly change the frequency characteristics of hand movements, thereby reducing the chance of coffee spilling."
But it turns out that walking backwards may be even more impractical--because people who trip over rocks or bump into passing colleagues are sure to get coffee spilled all over them
Therefore, to ensure that coffee does not spill, simply change the grip. The scientists 'advice is to use a "claw hand," which covers the mouth of the cup and grips the rim down
