Why can t the girl unscrew the cap, I can also unscrew the cap What does it mean

The common plastic bottle cap is fastened to the bottle mouth by fitting with the bottle mouth, in order to prevent the leakage of the bottle content and the invasion of external bacteria. Why can't girls unscrew the cap? Thinking about this catty problem from the perspective of torque seems to be able to be easily solved, according to the reference data, the tightening torque required for the bottle cap of traditional drinks is as follows:

Unified Coca-Cola.

Nongfu Spring. Robust.

And loosen the torque: unify Coca-Cola Nongfu Spring Robust. Adult women have less than 5% of the torque and 50% of the torque.

According to the maximum value of its release torque, it can be seen that the torque required to ensure that Coca-Cola is close to the torque of women, that is, nearly half of adult women may encounter the problem of not being able to open Coca-Cola. So many girls can't unscrew the cap, they may really can't.

There are two main reasons. One is that girls usually have less strength, and it is indeed difficult to open the bottle cap. On the other hand, some girls take this opportunity to create some opportunities for dialogue and communication, and also show their own relatively weak image.

Almost, most of the time it falls into the latter category. But usually carbonated drinks have tighter caps, and mineral water is easier.

Ha, it's not that she can't unscrew it.

It's a situation that can't be unscrewed, such as when there is a boy around or someone who can help. To show Chu Chu's pitiful appearance, let others think that she is a woman, without anyone's help, girls can still unscrew the bottle cap, or other businesses will design special drinks for girls.

This is because the force in the hand is not strong enough, so the cap cannot be unscrewed.

Mainly because of the pain in the hands, the little girls now have fine skin and tender meat, and when they hold the bottle cap hard and then twist it, it hurts to rub. Then there is the weakness when there are people, and the easy unscrewing of a cloth or paper when there is no one.

Girls are born with small hands, and then they encounter a tightly screwed bottle cap, naturally they can't unscrew it, and there is another reason, girls are more gentle, and when there are boys present, the heavy work of screwing the bottle cap should be done by boys.

It's normal, most girls have less strength, less hand strength, and some bottle caps are tightly sealed, and boys have a hard time screwing them, let alone girls.

The strength of the girls' hands is not greater than that of the boys, and the vast majority of them can't unscrew the cap. Of course, there are also girls who deliberately show themselves to be delicate and let boys show their love.

It's normal to have no strength, little strength, and can't unscrew it. And not all girls can't do without it, most of them can.

The reason why girls can't unscrew the cap is mainly because the strength is relatively small, and the cap will be unscrewed when the strength is great.

Girls can't unscrew the cap is related to the size of the strength, you can find tools to assist.

Because girls need to pretend to be gentle, which will make boys feel that she is very dependent on them.

It's normal for girls to not be able to unscrew the cap, and the girls themselves have very small hands.

Because they don't have that much energy.

Not all girls are like this, and most of the time they can be unscrewed.

Because if you unscrew it, there is one less excuse

Is it true that girls can't unscrew the cap?

It's not that it can't be unscrewed, it's loaded

Either the hands are weak, or this woman is very fond of pretending.

The girl just wants you to twist the cap on him

1. Most girls have less strength than boys, according to the National Health and Nutrition Survey 2011-2012: NHANES data: in the same age, men's grip strength is basically greater than women's grip strength.

There is a big difference in growth and development between men and women, which is mainly reflected in the ratio of sex hormones to muscle. When men reach puberty, the muscle content in the body will increase dramatically geometrically, and the male hormones in the male body will make the male muscles grow thicker, larger, and the weight they can bear is also larger. The estrogen secreted by a woman's body will make the woman's muscles grow more delicately and in a smaller size.

2. The sensitivity of the girl's hand to pain is relatively strong, when we twist the cap counterclockwise and in the opposite direction, not only will we obviously feel resistance, but also the thread on the cap will grind the hand. The longitudinal lines on the cap, called anti-slip lines, can not only prevent slipping, but also increase the friction between the fingers and the cap, but these lines can also cause us to have a strong pain in the process of twisting the cap, and many women can't bear this pain.

There are several methods: 1. Pad things. When you find that you can't unscrew the cap, you can put something under the palm of your hand, for example, find a rough cloth and put it under the palm, and then wrap the cap tightly to increase friction.

Because of the increase in friction, when you twist the cap by hand again, the same force will increase, and if you concentrate your strength, you can unscrew the cap instantly.

2. Raise your hand to pry the cap of the bottle. Using the principle of leverage, first find a stainless steel spoon, the spoon gently pry the edge of the bottle cap, pry a little gas in, and then you can easily open the bottle.

3. Turn the bottle upside down. Turn the bottle upside down for a period of time, and then pat the bottom of the bottle vigorously with your hands, which can effectively reduce the pressure of the air in the bottle, or use a lighter to roast the cap to soften the plastic on it.

Extended Materials. 1. Bean curd, also known as tofu milk, is a characteristic traditional folk food that has been passed down in China for thousands of years, because of its good taste and high nutrition, it is deeply loved by the Chinese people and the people of Southeast Asia, and it is an enduring delicacy.

2. Sufu is usually divided into three categories: green, red, and white. Among them, stinky tofu belongs to the "green side". "Large", "red spicy", and "rose" belong to the "red square". Sweet and spicy", "osmanthus", "five spices" and so on belong to the "white square".

3. Representative products: white bean curd is represented by Guilin bean curd. Guilin tofu has a long history and is quite prestigious, and it was famous as far back as the Song Dynasty.

It is one of the traditional specialties "Three Treasures of Guilin". Guilin fermented bean curd has a set of processes from grinding, filtration to shaping, pressing and drying, and mildew, and the selection of materials is also very particular. It is a commonly used food for people to make tofu and milk cubes, smooth and soft texture, orange and transparent surface, delicious and fragrant, rich in nutrition, increase appetite and help digestion, and at the same time it is a condiment for cooking.

In May 1937, at the National Handicraft Products Exhibition held in Shanghai, Guilin fermented bean curd was particularly respected for its outstanding shape, color, aroma and taste, and thus sold well at home and abroad. In 1983, it was rated as a national high-quality food. White bean curd is well-known overseas and is popular with people in Hong Kong, Macao, Southeast Asia and Japan.

1. After turning the bottle upside down, pat the bottom of the bottle with the palm of your hand and try again;

2. Blow the hot air of the hair dryer on the cap for about 1-3 minutes, expand the cap, and then unscrew it;

3. Wrap the cap with a dry towel, then hold the towel with your hand and twist the cap.

4. Soak the bottle in cold water, expose the bottle mouth, and then pour hot water on the bottle cap;

5. Use sharp objects such as kitchen knives, awls, etc., insert them into the gap between the edge of the cap and pry them outward.

1. Pat the bottom of the bottle with the palm of your hand.

When the cap cannot be unscrewed, you can first turn the bottle upside down, then tap the bottom of the bottle with the palm of your hand (you can pat it multiple times), and try again after patting.

2. Blow with a hair dryer.

When the cap cannot be unscrewed, it can be opened by using the principle of thermal expansion and cold contraction. Specific operation: Turn the hair dryer to the hot air shield, and then blow on the cap for about 1-3 minutes, so that the cap can be unscrewed after expanding.

3. Increase friction.

Sometimes the cap can't be opened, it may be because you have hand cream on your hands or there are oil stains, water stains, etc., you can wrap the cap with a dry towel, then hold the towel with your hand and twist the cap.

4. Pour hot water.

Similarly, using the principle of thermal expansion and cold contraction, the bottle body is soaked in cold water to expose the bottle mouth, and then hot water can be poured on the bottle cap.

5. Pry open the edge of the cap with a sharp object.

When the cap cannot be unscrewed, it is likely that the vacuum inside will suck the cap, and you can use sharp objects such as kitchen knives, awls, etc., inserted into the gap between the edge of the cap and pry it outward.
