Paper can hold water

Paper can hold water

"Paper can hold the water." This is incredible. I don't believe that this is true. An ordinary paper can hold a glass of water, killing me or not, but this is true. Things have to start from the beginning.

I remember that it was one afternoon in the winter vacation. I was concentrating on a book about science production. Suddenly a line of eye-catching words came into my eyes, "paper that can hold water." This is impossible. It is simply a fantasy. . Out of curiosity, I have always tried to experiment with the love. First prepared a glass, a flat piece of paper and some water. Pour some water into the glass, then slowly cover the flat paper with the flat paper, tightly bond the paper to the cup, and then turn the cup upside down quickly. At this point, unexpected things happened, and the water actually flowed out "unwelcomely" and sprinkled me. Hey, what is going on? I can do it according to the steps in the book? How can it be unsuccessful? I didn’t feel discouraged when I thought that Edison had invented the electric light after tens of thousands of failures. What did I get from this setback? If I give up like this, does it seem that I am too weak? Hard work pays off, after I have consulted the data, I finally found the reason for the failure: the cup should be filled with water, occupying the entire space of the cup, and I only poured half a cup of water, and half a cup of air, so the water will fall. It’s down. The paper can hold the water only if there is no air in the cup. After I understood this truth, I did another experiment. This time, the water was not only flown out, but also the paper was firmly held.

This experiment was so interesting. It not only made me experience the loss of failure, but also let me taste the joy of success, but also introduced me to the hall of scientific exploration.
