The so-called world is full of wonders. When it comes to important discoveries, people may think of scientists, which seems far away from our lives. However, as long as you are careful, you can find intriguing scientific phenomena everywhere in your life.

At breakfast, I peeled a boiled egg and put it upright on the bottle mouth. Half of the eggs are immersed in the bottle. I used to press the egg by hand, but when I pressed it into the bottle, it broke into several pieces. At this moment, it suddenly occurred to me: Can I put this egg in the bottle without damaging it? I asked my father this question, and he thought for a moment and said, "No problem."

Dad found some waste paper and kneaded it into a ball. He lit the paper with a match and carefully threw it into the bottle. Dad said to me, "Look at this, I'm going to do magic!" " "He put an egg with a shell on the bottle mouth, pressed it gently with his hand, and heard a bang, and the egg completely fell into the bottle.

I was very surprised. "What's the trick?" Dad said, "The trick is …" Dad was interrupted by his mother before he finished. "Don't worry, you'll know the trick when I do a little experiment."

I saw my mother find a glass bottle with a smaller bottle mouth, a lighter and a piece of paper. During the preparation, I asked my mother, "Mom, what experiment are you going to do?" Mother replied: "The experiment I want to do is' cupping'. As for the answer you want to know, after reading my experiment, you will certainly understand. " Mother rolled up her sleeves and approached the paper with a lighter. Then, as soon as she pressed the lighter, the paper burned. Mother unhurriedly put the paper into the bottle. After a while, the flame in the bottle went out, and my mother buckled the glass on her left arm in lightning speed. After a while, mother turned her hand to the downward direction of the bottle, but the bottle didn't drop! This is amazing. Mom asked me to try to pull the bottle down. I tried, but I, a "Hercules", couldn't do it.

When my mother saw my monk Zhang Er, she smiled and explained to me, "When the paper burned, the oxygen in the bottle was used up. When the oxygen is used up, the flame goes out, and the jar is pushed into the skin by external air pressure and firmly adsorbed on the skin, so that the bottle will not fall. In the egg pushing experiment, because the egg blocked the whole bottleneck, the outside air could not enter the bottle to replace the consumed oxygen, so the air pressure in the bottle dropped and the egg was 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.
