Pinch an egg

I don't know if you have tried to pinch eggs. Some people may think it is meaningless, because everyone knows that the thin shell of eggs will break when touched, and how many people know the little-known mystery.

At that time, I searched the internet at home and saw an interesting story, which said, "A Hercules can break a brick with his bare hands, but someone told him to break eggs." Hercules picked up the egg and pinched it for a long time, but it couldn't be broken. " I looked at it with a grain of salt and decided to find a chance to try.

On this day, my mother promised to cook my favorite scrambled eggs with tomatoes at noon. The thought of sweet tomatoes and slippery eggs makes my mouth water. I volunteered to help my mother at noon, and my mother agreed to let me beat two eggs. I took two eggs from the refrigerator first, and then a big bowl. Looking at the eggs, I thought: here comes a good opportunity for the experiment. The first egg, I knocked it into the bowl in the usual way, and the egg that broke as soon as I knocked it made me more suspicious of the story. The second egg, in order to prevent the yolk from spilling all over the floor when I crushed it, I specially aimed the egg at the center of the bowl. At this point, my heart was pounding and my palms were sweating. The scene of broken eggs seems to appear in front of my eyes. I closed my eyes and waited for the sound of eggs breaking. But to my surprise, when I opened my eyes, the egg didn't break. The "defeat" in the first round didn't discourage me, so I'm going to the second round. In the second round, I learned the lesson. This time, I held the egg tightly in my hands with both hands, then gritted my teeth, opened my eyes wide and tried my best to pinch the egg. Although I tried my best, when I thought the egg was "certain to die", it was already in my hand safely.

After listening to my words, my mother said to me earnestly, "Son, this is actually a scientific principle." Although the eggshell is thin, it is oval. When you pinch it, it will distribute all your strength evenly in all parts of the egg, so it can bear a lot of strength. Some buildings are built by using this principle. "After listening to my mother, I suddenly realized.

In fact, the world is really wonderful. I believe that as long as everyone loves discovery, observation and labor, they can meet with science. Today's society can be said to be inseparable from science. I believe that our bright eyes can find many beautiful things.
