I found one such problem in my life

This is the phenomenon of "siphoning".

Water can automatically rise a certain distance in towels, sponges, and other objects with tiny pores (including your tissues), but not indefinitely.

Power** Molecular force from water. Water molecules are always in motion, regardless of whether they are in **.

For a detailed and professional explanation, you can check the siphon.

It is possible to use this principle in life. It's just that due to the low height of the "climb", it is inconvenient to use, and it has little practical value.

You can experiment by placing one end of a paper towel in water, such as a water cup, and placing the other end on the outside of the glass, with the end face below the horizontal surface. After an hour, you should be able to see water oozing from the outside end.

It's like a tube. It's just that the traffic is small. In order to enhance the effect, the water edge in the cup is close to the edge of the cup, and it will be full.

Capillary phenomenon, each liquid has its own tension and will go upwards, counteracting the tension with the height difference of its own liquid column.

But it is very small, and it takes a long time to overcome the gap between practice and principle.

There's nothing wrong with your problem, it's the attraction of the paper towel to the water that sucks the water up. Personally, I feel that this attraction is formed by the tension of the water.

This is a capillary phenomenon, and I have done this experiment in elementary school, the rougher the paper towel, the larger the space between the fibers, and the faster and more water will be absorbed.

When we learn to find and solve problems in our lives, the first thing we experience is to have the ability to solve problems, which is an indispensable part of growth. In addition, we also learned the steps and methods of problem solving, which can deal with various problems in life, enhance our life ability and self-confidence. At the same time, we have also learned how to self-reflect and summarize, find out our own shortcomings, constantly improve our own process, exercise self-management and control ability, and make ourselves stronger and more mature.

In conclusion, mastering problem-solving skills is essential for our growth and life, helping us to better cope with difficulties and challenges, and to become a steady, decisive and resilient person.

Question 2: If you accidentally lose 100 yuan, only to know that it seems to have been lost somewhere you walked, would you spend 200 yuan to get the 100 yuan back?

Three hundred words is too much. Hehe.. However, the bounty is high...
