Can chewing gum really open coconuts by rubbing it into a cone? (Video screenshot)

　　The scorching summer is a good time to drink coconut milk and eat coconut meat. Here is an interesting question: If you only have durian, rubber band and chewing gum at hand, which one do you think you can choose to open a coconut quickly?

　　You may not imagine that researchers will tell you that opening coconuts with chewing gum is one of the simplest and most feasible methods.

　　If you want to know the principle, you need to know all kinds of substances of non-Newtonian fluid and Newtonian fluid.

　　Inflatable fluid: eat soft but not hard

　　— — Chewing gum, starch solution, wet sand on the beach and concrete slurry belong to expansive fluids.

　　What is the correct posture to open coconuts with chewing gum?

　　First, knead a few pieces of chewing gum into a cone, then put the tip up and the bottom flat on the table, then hold the coconut to a certain height with your hands and hit it hard on the chewing gum. We will find that chewing gum will not be smashed flat, but will break a hole in the coconut. Repeat this several times, and the coconut can be broken.

　　Why on earth does chewing gum have such magical power? In fact, the principle is — — Non-newtonian fluid principle. There is a gum-based component in chewing gum, which belongs to the shear thickening fluid in non-Newtonian fluid. The viscosity of this fluid will increase under the action of a large external force, and the greater the external force, the greater the viscosity.

　　When the coconut hits the chewing gum at high speed, the viscosity of the chewing gum increases rapidly, and at this time it behaves as hard as a solid, thus piercing the hard shell of the coconut. Once the external force is withdrawn, it will return to the nature of liquid. If the external force is small and slow, it will behave like an ordinary liquid with fluidity. It’s really a soft guy.

　　When this fluid thickens, its volume will expand slightly, so the shear thickening fluid is also called expansive fluid. Starch solution, wet sand on the beach and concrete slurry all belong to this kind of fluid.

　　The change of viscosity of expansive fluid is related to its internal structure. That is, when shear thickening occurs, a certain structure is formed inside the fluid.

　　Expansive fluid is usually a multiphase mixture, such as wet sand on the beach, which is a mixture of sand and water. When there is no external force or the external force is very small, the irregular sand grains are densely packed, and water can be evenly filled in the gaps between the sand grains to play the role of lubricant. When someone steps on the sand, the original tightly packed structure is destroyed, and the "dislocation" between the sand grains will increase the volume; At the same time, the water is forced to move around, and the flow is disordered, and the resistance will increase, and the flow of sand is more difficult because of the loss of lubricant. Therefore, the sand surface infiltrated by seawater on the beach is easier to walk than dry sand, because this characteristic of wet sand will make our feet less prone to sink.

　　Bingham fluid: sometimes like a solid, sometimes like a liquid.

　　— — Toothpaste, facial cleanser and hand cream belong to Bingham fluid.

　　Since there is non-Newtonian fluid, there must be Newtonian fluid. Fluids whose shear stress and shear rate conform to Newtonian fluid formula belong to Newtonian fluid. Water and air are Newtonian fluids, and their shear stress is directly proportional to the shear rate.

　　Any fluid whose shear force and shear rate do not conform to Newtonian fluid formula is called non-Newtonian fluid. Besides expansive fluid, non-Newtonian fluid also includes pseudoplastic fluid and Bingham fluid. All kinds of sauces, oils, polymer solutions, mud in the kitchen, and even blood and cell fluids in organisms are non-Newtonian fluids.

　　The shear stress and shear rate of Bingham fluid are also linear, but unlike Newtonian fluid, it has a yield stress, and it will flow only when the external force is greater than the yield stress.

　　The most typical Bingham fluid is toothpaste. When there is no external force, it looks like a solid. Only when we squeeze toothpaste hard, it will "flow" out of the tube, and when it is squeezed into the toothbrush, it can still maintain a certain shape without "falling down". If you don’t squeeze it, it won’t come out even if you turn the toothpaste tube upside down.

　　Similarly, we can infer that things like facial cleanser and hand cream are also Bingham fluids. The paint used in buildings also needs to be designed as Bingham fluid. We require that it can flow when mixing and painting, and at the same time, it will not flow down from the wall because of gravity after being painted on the wall, that is to say, the yield stress of the paint should be greater than its own gravity.

　　Like expansive fluid, Bingham fluid is a multiphase mixture. It is generally believed that the fillers in Bingham fluid form a three-dimensional network structure, which has certain strength and can resist low external forces; When the external force is large enough, the three-dimensional structure is destroyed and the filler will flow with the solvent.

　　Pseudoplastic fluid: bullying the weak and fearing the hard.

　　— — Blood, magma, yogurt, tomato sauce and shampoo are pseudoplastic fluids.

　　If expansive fluid is soft and hard, then pseudoplastic fluid is a bully. Pseudo-plastic fluid shows the opposite properties to dilatant fluid, and its viscosity remains constant at low shear rate, but decreases with the increase of shear rate. That is to say, the greater the external force applied to it, the smaller the viscosity it shows. So it is also called shear thinning fluid.

　　Many polymer liquids belong to this kind of fluid. The viscosity of a fluid can be understood as the friction between molecules in the fluid, and the greater the friction, the greater the viscosity. Solute in polymer liquid is a kind of molecule with large molecular mass and long structure. Without external force, they are usually in a curled state, and the molecules may entangle and collide with each other, resulting in high friction. When there is an external force, the curled molecules will spread along the direction of shear force, and the molecules will be arranged in parallel, so the friction between them will be reduced, and thus the viscosity will be reduced.

　　Blood, magma, yogurt, tomato sauce and shampoo all belong to pseudoplastic fluids. When we stir yogurt or tomato sauce slowly, we will find it more difficult, but when we stir it quickly, it will be easier. In fact, this is the reason above.

　　Pseudoplastic fluid has another interesting phenomenon — — Kay effect. When a beam of pseudoplastic fluid with high viscosity hits a solid surface, the solid surface will bounce the liquid beam back upward.

　　Observing the experimental phenomenon carefully, it is not difficult to find that a layer of fluid always accumulates below the rebounding water flow. Combined with the properties of pseudoplastic fluid, the whole process should be like this: the rapidly falling liquid jet impacts the viscous fluid pile below, and the viscosity of the fluid surface becomes smaller due to the impact force, forming a dimple-shaped pit after the impact. At the same time, the surface with reduced viscosity acts as a lubricant, and finally the falling liquid jet is bounced out.

　　Beijing Science and Technology Daily, July 9th (Reporter Liu Yuanyuan correspondent Feng Yi) Can eating more fruits and vegetables really prevent diabetes? The latest scientific research gives the answer.

　　The reporter learned from West Lake University that Professor Zheng Jusheng from the School of Life Sciences of this school, together with more than 40 nutritionists in Europe, proved from the perspective of blood nutritional markers that eating more fruits and vegetables is conducive to preventing diabetes (this article refers to type 2 diabetes).

　　The study concluded that if you eat 66 grams of fruits and vegetables every day, the risk of diabetes will be reduced by 25%. This provides valuable suggestions and references for dietary guidance in the field of public health. The research results were published online in the British Medical Journal (BMJ) on July 9th, Beijing time.

　　"We have tracked and recorded more than 10,000 cases of diabetes in eight European countries, including Britain, France, Germany, Italy, Spain and Denmark, and compared more than 13,000 healthy people. From the perspective of nutritional markers, we found that eating more fruits and vegetables really plays a positive role in preventing diabetes." As the first author of the paper, Zheng Yusheng said.

　　In this study, the research team recorded seven kinds of nutrients in the blood of the experimental population, including vitamin C and six kinds of carotene. These seven blood indexes have been proved to be nutritional markers corresponding to the effective intake of vegetables and fruits. Generally speaking, the more fruits and vegetables are consumed, the higher the content of these seven indicators in the human body.

　　Through regular measurement and tracking, the research team found that the higher the nutritional markers in the body, the lower the risk of diabetes, which shows that eating more fruits and vegetables can effectively reduce the risk of diabetes. Statistics show that the seven nutritional markers have increased by a standardized unit — — The risk of diabetes will be reduced by 25% if you consume 66 grams of fruits and vegetables every day.

　　According to reports, more than 10,000 diabetic cases and 13,000 healthy control groups were screened from more than 400,000 people through nearly 10 years of follow-up, so there are long-term data to support the reliability and stability of the conclusion.

　　"Many teams have done similar research before. Some teams use questionnaires, which may have the subjective will of the experimenters, so there may be errors in the experimental results. The samples of other research teams may be only a few hundred people, and the tracking time is relatively short, so the statistical data is not representative. This study has a large sample of participants and a long experimental time, and it is of great significance in the field of public health to verify the results through a more scientific method. " Zheng Yusheng said.

　　Xinhua News Agency, Beijing, February 5thTitle: Fu "Rabbit" celebrates reunion and Yuan "opens a new game — — Scanning of celebrating Lantern Festival in various places

The fifteenth day of the first lunar month is the Lantern Festival, also known as the "Shangyuan Festival", which existed in the Qin Dynasty more than 2,000 years ago. Emperor Wen of the Han Dynasty ordered the 15th day of the first month to be the Lantern Festival. Eating Yuanxiao, enjoying lanterns, solve riddles on the lanterns, setting off fireworks and other activities have existed since ancient times and have been passed down to this day.

I believe that many foodies have already prepared all kinds of dumplings at home, and I look forward to the scene of family members sitting together and eating dumplings. Whether in the north or the south, eating glutinous rice balls is an essential highlight of the Lantern Festival. The difference is that it is called "Yuanxiao" in the north and "Tangyuan" in the south. Many people who pay attention to customs think that "Lantern Festival is not counted without eating glutinous rice balls". How can we enjoy glutinous rice balls while taking care of our health?

Note the "stuffing" trap

The fillings of Yuanxiao are generally green red silk, peanuts, sesame oil, jam, sugar, etc. The fillings of glutinous rice balls are generally bean paste, black sesame, shepherd’s purse, pork and so on. The two methods are different, but the main component of the crust is glutinous rice flour, and the stuffing also contains more oil (nuts such as sesame seeds and peanuts, chocolate and lard, etc.), so whether it is Yuanxiao or Tangyuan, the heat is very high. As the folk song goes, "Tangyuan can be used as tea rice", and three medium-sized Tangyuan (1/2) are equivalent to the carbohydrate of half a bowl of rice. The energy of two black sesame dumplings is about 300 kilocalories, with 16.4 grams of fat and less other nutrients. Eating more will increase energy and fat intake. Moreover, the starch contained in glutinous rice is amylopectin, which is not easy to digest and absorb in the stomach. Therefore, no matter from the aspects of energy intake or digestion, it is not appropriate to eat dumplings as a staple food in large quantities.

Sugar control is very important.

Although compared with the traditional glutinous rice balls, sugar substitutes are used in making sugar-free glutinous rice balls, the glycemic index of white glutinous rice, black glutinous rice, sticky millet and rhubarb rice is around 100, and the blood sugar rises rapidly. Even sugar-free dumplings are recommended for diabetics to eat as little as possible. In addition, you can eat some vegetables or protein-rich food before eating glutinous rice balls, which will help reduce the blood sugar reaction after meals.

Prevent accidents

1. For the elderly, due to the gradual decline of digestive function, especially the slow swallowing reflex of the elderly, they may get stuck in their throats because they eat more urgently, resulting in difficulty in breathing and even suffocation. Therefore, the elderly must chew slowly when eating dumplings.

2. For infants, if the baby at home is under three years old, it is recommended not to let him try glutinous rice balls easily. After all, glutinous rice balls are mainly made of glutinous rice. If they are eaten by a baby under one year old, they may stick to the esophagus and have the risk of blocking the respiratory tract. If it is a one-or two-year-old baby, it is still not easy to bite peanuts and other fillings in the glutinous rice balls to prevent suffocation. In addition, because the baby’s digestive function is still weak and the swallowing reflex is not well developed, even if the baby over three years old is given glutinous rice balls, parents must look after them. It is best to divide the glutinous rice balls into small pieces in advance to prevent accidents. If your baby is suffering from respiratory diseases, such as cough, you should also eat dumplings as little as possible to prevent the illness from aggravating.

The glutinous rice balls that have just come out of the pot are steaming, so remember to taste them slowly and slowly to avoid burning your mouth. Just eat two or three medium-sized snacks at a time, and don’t be greedy for Doha! Finally, I wish you all a happy Lantern Festival, a happy family and a reunion!

Original title: "[Concern] How to taste dumplings healthily during the Lantern Festival on the fifteenth day of the first month? 》

Read the original text

In the cold winter, Beijing is freezing. In order to provide a warm haven and resting place for lottery buyers and pedestrians who travel in the cold, Beijing Sports Lottery stores have started "warm management" one after another, helping everyone dispel the cold and protect their health with warm environment layout and enthusiastic service.

Sphygmomanometer plays a big role

"Small seeks you this incredibly have a sphygmomanometer? Then I have to test it. " Another lottery buyer who walked into the 36245 Sports Lottery Store in Haidian District in the cold wind quickly found the electronic sphygmomanometer specially placed in a conspicuous position by the agent Mr. Mou, and took the initiative to ask for blood pressure measurement.

In September 2023, Beijing Sports Lottery launched the "Healthy China Healthy Sports Lottery" activity, and established the Beijing Sports Lottery Health Benefit Station through the form of "Sports Lottery+Medical Care". Beijing Sports Lottery has equipped the first batch of 80 health benefit stations with electronic sphygmomanometer, oximeter and body fat scale as convenience facilities in the sports lottery health benefit station for use in the store. This winter, these health facilities played a big role. Mr. Mou told reporters: "Our store has an electronic sphygmomanometer sent by Beijing Sports Lottery Center, and my wife has a nurse qualification certificate. She is very concerned about the health of lottery buyers on weekdays and has been thinking about how to serve everyone as much as possible."

"Cold weather is very unfriendly to cardiovascular and cerebrovascular diseases. After Beijing cooled down this year, I put the sphygmomanometer in a conspicuous position in the store, which is convenient for the lottery buyers to test themselves. For older people, as well as tourists from the south, I will take the initiative to persuade them to measure their blood pressure and pay attention to their health. " Mr. Yan said.

Hot ginger soup to create a warm haven

No matter how windy and slippery the road is, there are always some people who have to go out. The Beijing Sports Lottery Store with sufficient heating and hot water can be their warm haven. "The people in this store are very good. I am actually waiting for someone nearby. The little girl said to let me come in to warm up and have a cup of hot water. It’s still warm in the house, but the enthusiasm of sports lottery is warmer and warmer in my heart. " In the 43276 Sports Lottery Store in Yongledian Town, Tongzhou District, an uncle praised the salesman Li Hongyan.

"There is no heating in the sports lottery store, but I turn on the air conditioner every day. The store is as warm as spring, and many people who go to the market will come to my store to rest." Li Hongyan said, I am warm to every guest who comes in, even if they are not here to buy lottery tickets, but just to take shelter, drink water or borrow a pump.

There are many sports lottery shops in Beijing, like Li Hongyan, which prepare hot water in their shops to provide a safe haven for their guests. Others specially cooked ginger soup at home and took it to the store in a thermos. "It is said that drinking ginger soup can better drive away the cold and prevent colds, so I have prepared some for people in need. It is not easy for people to go out in cold weather, and good health is very important. " Li Yong, a consignment agent in Tongzhou District, said.

Warm service can drive away the cold.

A cup of hot water can warm your hands, a warm room can warm your body, and a warm word can warm your heart. When it snowed before, many Beijing Sports Lottery people not only swept away the snow and ice in front of the door, but also swept the road at the door together with the snow in the nearby community, and laid anti-skid mats in the store, posted anti-skid tips, and used warm words and temperature service to drive away the cold for the guests who entered the door; In Yanqing District, which is colder than the urban area of Beijing, when it was found that heating and air conditioning could not effectively raise the temperature in the store, the Sports Lottery Store No.48022 decided to temporarily add a salesperson to reduce the waiting time of lottery buyers. There are also physical stores that strive to consider the possible needs of lottery buyers and prepare facilities in place. For example, umbrellas, chargers with various interfaces, band-AIDS, cold medicine, shoe polish and brush, disposable handbags, newspapers and magazines, chewing gum, etc. are always available.

It’s warmer in Leng Qing, and the cold wind can’t blow away the light and heat of sports lottery. In the new year, Beijing Sports Lottery and the respectable and lovely Beijing Sports Lottery people will continue to send more true feelings and warmth to the lottery buyers and the society.

　　First, the hidden rules

　　If one day Zhang Yimou suddenly wants to hide me, I think I will go without saying anything! Maybe, I can go to Hollywood for decades. God ~ Give me a hidden rule when I have to, but only if you keep your word, I don’t want to be Yu Zhang!

　　Second, the sex scandal

　　Women can also use men to succeed in the upper position. For example, I took nude photos, but I don’t know where to send them. If John Woo says, call me to take Red Cliff 2. The premise is to send nude photos, I must send them! Is there a master planner who can teach me how to send it so that I can become popular?

　　Third, selling privacy

　　I really want to find someone to give me a lot of money, and then I’ll make myself beautiful! To be the first beauty in China, after all, I think I still have this foundation, and then the privacy is absolutely red!

　　You can learn from Sister Furong’s madness, and you can learn from Lan Dong and mean girls’s nonsense, and your popularity will definitely rise. In fact, I also want to say that I want to find a boss to support me, give me money, give me a car, give me a house, I will give you health and give you happiness! Has anyone come to sign up? Finally, I just want to say that a good planner is the most important thing. I want to find a planner, and we will plan it well. Then I will go up and you will follow me. To succeed is to do whatever it takes, which has nothing to do with spiritual beauty!

　　Just two days after the news of French, German, Japanese and other commercial banks and insurance institutions applying to land in China came out, two more news came: First, on May 2, the Central Bank of China confirmed that the first foreign-funded payment institution had applied to the Central Bank of China for business. This means that foreign payment institutions have taken the first step to enter the China market. Second, on the same day, it was reported that a foreign company had started to apply for a credit investigation license in China.

　　This is the embodiment of China’s further financial opening.

　　Let’s look at the company that applied for third-party payment, named WorldFirst, which is a British-funded company. In April 2018, WorldFirst just launched the first collection product for cross-border B2B sellers in China — — World Account to solve the problem of cross-border payment for cross-border e-commerce sellers, so it is very important to obtain a third-party payment license in China, otherwise, the development of China market will be limited. The application of WorldFirst to the Bank of China for a cross-border business payment license indicates that China’s financial opening is expected to go further in the field of third-party payment.

　　The company that applied for the credit information business license is even bigger. Yiborui Company, headquartered in Ireland, is a giant of credit information business in the world, with business all over the world and huge branches in the United States.

　　Generally speaking, if the central bank confirms the receipt of the application, it means that the central bank has actually started the process of approval. Therefore, these two cases, some low-key applications, were officially confirmed, which means that China’s financial opening-up is real, and it is a fence to cut the knife and cut the flesh.

　　The third-party payment market in China has achieved great success in recent years. The well-known third-party payment companies represented by WeChat and Alipay have made eye-catching profits in this field. Ant Financial has mastered Alipay, and its valuation has surpassed many financial companies in the United States by hundreds of billions of dollars. However, the size of WeChat Tenpay is not inferior to Alipay. Of course, its actual valuation should also be around here. Even so, China’s third-party payment market still has great potential to be tapped. For China’s huge domestic third-party payment market, foreign capital used to be out of reach. But now it seems that soon, foreign capital can come in to participate in the competition and share a piece of the action.

　　The credit investigation market in China has just started. There is a vast space for both corporate credit investigation and personal credit investigation, and many aspects are still blank. I am afraid the market potential in this respect is no less than that of third-party payment. Different from third-party payment, there is no strong competitive opponent in China in this respect, that is to say, if foreign capital comes in, it is basically a blue ocean with huge profits.

　　Therefore, China’s opening up in these two areas is really very bold and courageous.

　　No wonder countries, especially several developed countries, have been acting so frequently recently.As long as they have some market judgment, they will never ignore the huge space of China’s financial market. Whoever falls behind in the process of opening China’s financial market will lose half of the future first. From a global perspective, I am afraid that the two major financial opening dividends that China wants most are American companies. Let’s look at the third-party payment market in China, which is the big fat that companies with payment services in the United States, such as Apple and paypal, want to get. Apple has previously entered the payment market in China through the cooperation with China UnionPay, but after all, it is a four-way payment, and its business development is not satisfactory. Therefore, in the competition with WeChat and Alipay, Apple, which is far behind, should dream of getting a third-party payment license in China.

　　Needless to say, the three major rating agencies in the United States, Standard & Poor’s, Moody’s Investment Services and Fitch Ratings Limited, are all giants in the global credit reporting field. If they can’t successfully enter the credit reporting market in China, or lag behind other competitors in the pace of entering China, they will probably have a great adverse impact on their future competitiveness.

　　However, if American companies really lag behind their western counterparts, it is not China’s fault. China people believe in "making money with harmony". After all, the United States initiated a trade war with China, and public opinion in China could hardly accept the result: open these fields and let those guys who threw stones at themselves happily take away the benefits. Needless to say, no one has the guts!

　　　　In 1972, I visited Deng Xiaoping in Nanchang, Jiangxi, and spent an unforgettable New Year at Deng Xiaoping’s home. Deng Xiaoping’s cooking skills, Zhuo Lin’s enthusiasm, and his friendship with Deng Lin’s brother and sister all remain fresh in my memory.

　　　　Visiting relatives in Nanchang on New Year’s Day

　　　　On the eve of New Year’s Day in 1972, my sisters Da Rong and Er Rong went to Nanchang from Linchuan County, Jiangxi Province to visit Uncle Deng Xiaoping. I remember that it was a cold winter. There was a layer of mist on the boundless Ganjiang River, and no ship was seen. The distant mountains were gray, and the vegetation along the river was withered and trembling in the cold wind. We came to the guest house of the provincial party Committee by the Ganjiang River, which is the designated meeting place.

　　　　It is said that after Deng Bobo and his family came to Jiangxi, they lived in a small building of Nanchang Infantry School. There was no heating or hot water in the building. When they wanted to take a bath, the old man had to boil the bath water downstairs and carry it to the bathroom upstairs in buckets, which was inconvenient. Moreover, it was easy for the old man to catch a cold when taking a bath in winter. This problem dragged on for a long time. When Huang Zhizhen, a former veteran cadre of Jiangxi Provincial Party Committee, learned about it, he made arrangements for Deng Bobo’s family to take a hot bath in the provincial party committee guest house every weekend. When I came to the guest house, Uncle Deng Xiaoping’s family happened to take a bath here.

　　　　In the living room on the second floor of the hostel, we first met Aunt Zhuo Lin, Deng Lin and Mao Mao, who had just taken a bath and were combing their hair. Uncle Deng asked them to wash first and then wash themselves. When I saw Aunt Zhuo Lin, my sister and I were filled with emotion and tears. Aunt Zhuo Lin and my mother Xiao Li were good friends during the Yan ‘an period, and they had a lot of contacts. Uncle Deng came out of the shower and was very happy to see us coming. Perhaps it was because he had just taken a shower and his face was flushed and radiant. He speaks Sichuan dialect, and we also speak Sichuan dialect, because we grew up in Chengdu and have a local accent. Visiting Uncle Deng has always been our wish. Our family has a good relationship with Uncle Deng’s family, and their children grew up together. First, we reported to Liu Junxiu, deputy director of Jiangxi Revolutionary Committee, who worked in the Jinsui Military Region with my father Li Jingquan during the War of Resistance against Japan period. Our wish was realized through the contact between Uncle Liu and Uncle Deng’s family.

　　　　Uncle Deng asked about our work and life with concern. I told him that my sister and I came to Jiangxi in 1969 and settled down in my father’s hometown, Linchuan County, to work as farmers, relying entirely on earning work points to support ourselves. Speaking of which, my sister and I took out two fish brought from our hometown, which were caught by the villagers from our pond, and some eggs saved. I told Uncle Deng that these are all fruits of labor. Please accept them for the whole family to taste. Seeing that it was getting late, we were ready to leave. On hearing this, Uncle Deng immediately said, "Don’t go today, come to our house for a few days."

　　　　Chinese New Year at Uncle Deng’s house? The Provincial Revolutionary Committee may not agree, and I am also afraid of bringing trouble to the Deng Bobo family. "I’m afraid of you. You are all little dolls. Tomorrow is the New Year. How can you go?" Uncle Deng said. Aunt Zhuo Lin also said, "You have come a long way, but you haven’t finished yet. Come home with us and spend the New Year together. Don’t worry, I’ll tell them that I can stay at home. "
