The so-called vast world contains all kinds of wonders.

When talking about major discoveries, you may think of scientists, who seem to be far removed from our lives.

However, as long as you pay attention, you can find intriguing scientific phenomena everywhere in your life.

During breakfast, I peeled a hard-boiled egg and placed it vertically on the mouth of a glass bottle. A small part of the egg was submerged in the bottle. I used to press the egg with my hands. When the egg was pressed into the bottle,

When I put it in, it broke into several pieces. At this time, I suddenly thought: Can I put this egg into the bottle without damaging it? I raised this question to my father, and my father thought for a while and said: "It should be no problem.

." Dad found a few pieces of waste paper and crumpled it into a ball. He lit the paper with a match and carefully threw it into the bottle.

Dad said to me: "Watch out, I'm going to do a magic trick!" He put a peeled egg on the mouth of the bottle and pressed it gently with his hand. There was only a "pop" sound, and the egg fell into the bottle intact.

inside.

I was very surprised, "What's the secret here?" Dad said, "The secret is..." Before my father could finish speaking, he was interrupted by his mother, "Don't worry, after I do a little experiment, you can

You will know the trick." I saw my mother find a glass bottle with a smaller mouth, a lighter and a piece of paper. While preparing, I asked my mother: "Mom, what are you doing?

What experiment are you going to do?" Mom replied: "The experiment I'm going to do is 'cupping'. As for the answer, you will definitely understand it after reading my experiment."

The lighter came close to the paper, and then she pressed the lighter, and the paper "chi" burned. Mom calmly stuffed the paper into the bottle.

After a while, the flame in the bottle went out, and my mother quickly put the glass on her left arm. After a while, she turned her hand to face the bottle downwards, but the bottle didn't fall!

This is amazing.

My mother asked me to try to pull the bottle off. I tried, but I, a "strong man" like me, couldn't pull it off.

Seeing my confused look, my mother explained to me with a smile: "When the paper burns, it uses up the oxygen in the bottle. After the oxygen is used up, the flame goes out, and the bottle is pushed into the skin by the pressure of the outside air.

It is firmly adsorbed on the skin, so the bottle will not fall off. In the experiment of pushing the egg, because the egg sealed the entire bottleneck, the outside air could not enter the bottle to replace the consumed oxygen.

The air pressure in the bottle decreases and the egg is sucked into the bottle. “There is science in life, and science is in life.

As long as we explore and study, any mystery will be solved.
