People still clearly remember that there was an exciting light achievement program at the Spring Festival Gala broadcast live by CCTV. I saw the performer standing on the glass supported by two balloons, standing on the straightened paper, and hanging his body on the fluorescent tubes hung by two paper rings. As soon as the TV station broadcast this program, some newspapers and magazines followed suit and published some articles promoting lightness skill, saying that "Qigong can be as light as a swallow if it is practiced to an advanced level." What's the saying? "When this qigong master performs, his body can change from 60 kilograms to 5 kilograms, and he can walk on water" and so on. , in order to flaunt qigong people have superhuman ability. Many people who usually take "seeing is believing" as the standard believe this without hesitation. However, there are always some people in the world who love to "tell the truth". These people never simply accept the superficial phenomenon that the outside world has spread to their eyes, but always love to get to the bottom of it. Someone personally tried the three kinds of qigong performances mentioned above. Although the experimenter didn't practice lightness skill or lose weight during the experiment, the experimental results are the same as those of famous lightness skill performers, and they can still stand on balloons and paper bridges and hang them on fluorescent tubes with paper rings. On one occasion, we performed and exposed many so-called qigong stunts prevalent in society at the report meeting of "Promoting Scientific Qigong and Breaking Feudal Superstitions" held in Beijing Science Museum. Such as "mind literacy", "broken stone in the belly", "brick in the head", "smoking in the palm" and "motorcycle with alcohol, tobacco and water in the mouth". Of course, it also includes the lightness skill above. When participants (including journalists) who have never practiced Qigong are invited to perform these performances, they are still successful. What is the reason? Let me introduce the mystery of flying skill first. Lightness Skill was originally a practice method in martial arts, requiring practitioners to tie sandbags to their feet to practice jumping, so as to increase their ability of prancing in high jump. However, in recent years, with the rise of Qigong fever, Qigong has lost its original connotation and become a patent for Qigong masters to practice Qigong. However, through the fact that people who have never practiced Qigong can successfully perform Qigong, we can draw the following conclusions: Qigong performance has nothing to do with Qigong, Qigong performance is not the patent of Qigong masters, and people who perform Qigong will not lose weight during the performance. In fact, qigong performance uses the principles of physical mechanics and people's misunderstanding of common sense when they know things. As we all know, common sense is the knowledge that people get from long-term experience, and there is a difference between common sense and science. Common sense is not always correct, and sometimes it may be completely incorrect. Therefore, common sense, as a criterion for judging things, often makes mistakes. For example, we often say that "practice makes perfect", which is universally acknowledged. However, only by training according to the correct essentials can swimmers become more "familiar" and "skilled". On the other hand, if you practice the "familiar" posture according to the wrong essentials, it will not only affect the improvement of speed, but also be difficult to change. It can be seen that practice makes perfect, which is not correct in this case. According to common sense, balloons and paper bridges are so light and thin, how can they support the weight of such a big person? The standard on which this understanding depends is common sense. The common sense understanding of the problem of lightness skill just makes people form a misunderstanding. In fact, although the balloon is thin, after inflation, according to the physical pressure formula, two balloons can completely support the weight below 70 kg. In other words, anyone can succeed as long as your weight does not exceed 70 kilograms and you pay attention to the skills and methods when stepping on the ball. If you want to ensure the success of the performance or increase the excitement by adding weight, you can also set up four balloons in pairs and inflate them. When you perform, you can safely ignore them, but the audience cannot see them. Take the paper bridge station as an example. If a piece of paper is torn along the grain, it is very easy to be torn, indicating that the tensile strength of the paper is very low, but if a piece of paper is torn along the grain, it is not easy to be torn off. Physically speaking, the tensile strength of paper is great. Generally, hard paper has this tensile strength. It's really not the performer who has superhuman ability to lose weight during the performance. Except balloons and paper, other light performances, such as stepping on eggs and stepping on matchboxes, are the same. Interested parties may wish to give it a try to ensure success. In a word, we should get some enlightenment from the revelation of the mystery of "lightness skill". For example, don't judge things by common sense too much, and don't easily believe what you see with your own eyes, because people's eyes often can't distinguish between natural and artificial illusions such as hallucinations and illusions, and can't identify the essence of things. In addition, it is also extremely important not to uncritically believe and accept the propaganda of Qigong masters who claim to have superhuman abilities, and not to believe the propaganda made for them by other propaganda tools. Finally, teach readers a simple identification method. Let the master who claims to practice the function of losing weight perform on the weighing scale to see if the number of pointers on the weighing scale can decrease with the master's practice. This method is simple and objective, and can explain the problem on the spot.
