In my life, I discovered a little secret:
In a family cleaning, my mother asked me to clean all the tables. I think it's not easy. Although there are many tables at home, we should clean them quickly! I immediately put my hand on it, took a rag, poured water into the basin and started my work.
First of all, I came to the living room and wiped the table with a rag, but there were some oil stains on the table that could not be wiped off with clear water, as if they were soaked in the table. I had to call my mother, and she said she would use detergent to clean it. I tried it, but I didn't expect it to be wiped off. It's as clean as new.
In this way, I wiped several tables and cleaned them all, but when I wiped the computer desk, I encountered difficulties again. The computer desk may be a lollipop left by others when they came to my house to play. It was saccharified and could not be removed with cleaning liquid. Later, I thought of a good way to soak the rag in boiling water, wipe it with a hot cloth, let the sugar dissolve, and then wipe it clean. Just try it. The sugar stains are gone.
This time I learned that cleaning liquid can wipe off oil stains and hot water can wipe off sugar stains.
The mystery of life composition 2 When the class began, Mr. Wu came in with a smile and mysteriously took out a bottle. We are very confused. We don't know what medicine the teacher is selling. At this time, the teacher asked, "Who knows how to deflate the bottle without external force?" The students looked around, and Zhang Fei assumed a pair of eyes with big eyes and small eyes. Nobody knows. At this time, the teacher picked up a cup of warm water and poured it into the bottle. The bottle is still full and hasn't changed at all. I don't think the teacher is joking with us. I'm a little skeptical. Teacher Wu seems to have read my mind. She asked everyone, "If I pour out the hot water, will the bottle change?" The students thought: hot water has not changed in the bottle, nor has it changed when poured out. The teacher smiled and quickly poured out the hot water and closed the lid. In a flash, the bottle was "hungry" and the originally bulging stomach flattened. The students were so surprised that their mouths turned into an "O" shape that they could swallow a big jiaozi in one bite.
Why is this happening? I went home to check the information. It turns out that warm boiled water heated the air in the bottle, and the air pressure outside the bottle was greater than that inside the bottle, so the air pressure crushed the bottle.
There are so many mysteries in life! I can't help but sigh: you must be good at discovering and thinking to know more knowledge. Today, we did an interesting experiment by ourselves. Want to know what experiment it is? Look down with me.
The Mystery of Life Composition 3 One day after dinner, I wanted to help my parents wash the dishes on a whim. My parents readily agreed, and I pushed them into the living room and said, "Wait here for the good news of my victory." Ready to show my skills, I put on my apron and went into the kitchen armed to the teeth.
As soon as I entered the kitchen and came to the pool, I picked up a bowl and washed it under the tap. After several flushes, I put some detergent in. Although I worked hard, it backfired-I wiped it many times before I cleaned it. Now I'm a little anxious, thinking, at this rate, these bowls will be washed until tomorrow morning! No, I have to find a way, so I put more detergent, but the effect is not great. At this time, my parents said loudly in the living room, "Forget it, son, let's wash for a while."
I was really worried and sweated. Just as I was wiping my sweat with my hand, I accidentally bumped into the handle of the faucet and turned on the hot water switch. In an instant, a stream of hot water flowed down the faucet, so I put detergent on the hot water and washed it. The washing effect is really good, and the oil stains on the dishes and chopsticks can be washed easily. I also washed quickly and got praise from my parents. Afterwards, I have been thinking about why hot water is so easy to wash. Can hot water wash the oil clean and separate the oil from the chopsticks? I looked at it with doubt, and it said: The melting point of oil is relatively high, and oil can be dissolved at a certain temperature. Sure enough, all the problems were solved.
In the future, we should observe life more and find more tips in life, just like today, so as to get twice the result with half the effort.
The Mystery of Life Composition 4 One night, I went home and did my homework for a while. Suddenly my eyes went black and I couldn't see my fingers. It turned out to be a power failure. I have to do my homework, so I have to stumble all the way to find candles.
I have nothing to do after finishing my homework. I'm bored and can only observe what's on the table. After a while, I was surprised to find the paper drawn by candles "dancing" on the table. I can't figure out why the paper is "dancing". "Squeak" is the sound of opening the door, but mom and dad are back. I think they can give me a suitable reason, so I ran to find my parents. But the result is this-my mother ignored me at all, and my father just smiled and continued his business.
Disappointed, I returned to my bedroom. Suddenly, it occurred to me that I could find a silent teacher-book. They waited in line for me to read aloud. I am very busy, and I haven't learned to read quickly. I can only read word by word, and no one escapes. Finally, through my unremitting efforts, I found the reason. It turns out that this is a trick of cold air and hot air. The fire burned by candles has a temperature, but the temperature at home is cold. The hot air rises and the cold air falls, which eventually leads to the busy drawing paper. In order to prove the reason I found, in winter, I took a short sleeve, moved a heater and walked into Grandpa Dong's arms. I put my clothes in front of the heater and found that the clothes jumped more than paper!
It turns out that in this beautiful world, there are so many mysteries waiting for us to explore!
The Mystery of Life Composition 5 I went back to my hometown this Saturday and found that there was an extra henhouse in my hometown, so I went to have a look at it. As soon as I got to the henhouse, I found a big fat cat staring at the chickens in the henhouse. The cat ran away as soon as it saw me! I thought: Hey, why did the cat come to the henhouse? Does the cat want chicken? No way, I've only heard that cats eat fish! I asked my grandfather doubtfully, "Grandpa, grandpa!" " Why is there a cat next to our henhouse? Grandpa said, "Because that cat wants to eat our chicken!" " ""I said, "How can a cat eat chicken? Even if you do, why not eat the chicken from grandma's house next door? Grandpa said, "That's because cats only eat chickens, and the chickens in grandma's house next door are bigger!" "I understand, go to the henhouse to observe for a long time! Just then, I found two chickens eating a stone the size of a soybean. It seems that they still eat with relish! I immediately let out a cry! Grandpa rushed over and asked, "What's the matter?" I said in surprise, "I just found two chickens eating stones with relish!" " "Grandpa said," It's no big deal! It's normal for chickens to eat stones! "I then asked," Why do chickens eat stones? " Grandpa said: "Chickens eat stones to exercise the digestive ability of their stomachs!" " "After I listen to an epiphany!
There are too many mysteries in life. Cats eat chickens and chickens eat stones. It's incredible!
The Mystery of Life Composition 6: The Mystery of Life-The Empty Compression Package of Truth
After dinner, mother went to the bedroom to tidy the wardrobe. I quickly followed her and wanted to help her with some work.
Mother first folded the dried thick quilt, put it in a big blue bag, and then sealed the zipper on the side of the bag. Then, I picked up a pump like a balloon and asked my mother, "What is this?" Mother said, "This is a manual air pump, which is used to pump the air out of the bag." "What do you mean?" I asked my mother puzzled.
My mother said to me: This blue bag is called a vacuum compression bag. Used for quilts, pillows and cotton-padded clothes. Mainly put it in the closet to save room. It can also be used to prevent dust and moisture. Just open the air nozzle cover, aim the air pump at the air nozzle, and pull the air pump to inhale, so that air can be sucked out of the bag air, and the thick quilt will become very thin. Then I tried for a while, my arm was a little tired, I had a rest, and then I began to work. After five or six minutes, the bag flattened. After flattening it, my mother covered the microphone.
My mother said, "What happened after the air was pumped out?" I opened my eyes wide and said, "What a change. Just now, the quilt was about seven or eight Chinese books thick, and now there are only three. Mom, it's amazing. "
Facts have proved that there are so many little secrets in our lives.
The Mystery of Life Composition 7 The teacher said that there would be an experiment today, and my mind was full of question marks: What experiment should I do? The teacher wrote "the flame that can't be extinguished" on the blackboard, and I thought to myself: How can the flame not be extinguished? Can it really blow out? Anyway, go and do the experiment!
In this experiment, three props should be prepared, namely lighters, paper and tape. When I pressed the button of the lighter, the flame jumped out at once. I was so shocked that I thought it was on fire! What a close call! The teacher made the paper roll into a trumpet, and taped the edges, just like hats, binoculars and flashlights. I thought, why are you rolled up like this? You're not a pipe, are you?
It was supposed to blow the flame, but Xiao Lishi began to blow the flame. He took a deep breath and blew twice before blowing out the small flame. The students in our class are very excited and everyone is eager to try. The teacher took the flame away, but Xiao Lishi did not blow it out with great effort. The flame seemed to say, "You can't blow it out! Can't blow it out! " I don't think it will ever blow out like this. At this moment, Xiao Lishi gathered all his strength, blew out the flame in one breath, and we began to get excited again.
Blow an inch, she blows gently, and the flame is defeated. We clapped our hands excitedly. Later, I found out that she had the torch upside down. No wonder it blows out so easily!
Why can a small one blow out the flame easily? Because the small head of the "horn" is facing the flame, the airflow is relatively concentrated; When the big head is aimed at the flame, the airflow is dispersed and it is not easy to blow out.
There are many mysteries in life, waiting for you to discover!
As we all know, the flame goes out when you blow it gently, but in class today, the teacher said, "I'm going to do an experiment today, called' the flame that can't be extinguished'." I was puzzled and thought: Is the flame enchanted? How amazing!
To do this experiment, you must have a lighter and a piece of paper. The teacher made this flat paper roll into a funnel shape and glued it with tape. It looks like a cylinder, an ice cream cone and a telescope.
Next, the first one is that I will go on stage to do the experiment. I thought: such a small flame is no match for me at all. I picked up the funnel, aimed the big end of the funnel at the flame and took a deep breath forward. Eyes wide open, mouth constantly exhaling, face red. But in any case, it just can't be blown out, and the flame swings from side to side, as if dancing proudly. Is the flame really enchanted?
CiCi is next. I am puzzled, because I am a strong person, how can she be blown out?
CiCi picked up the funnel and pointed his head at the flame. She took a deep breath and blew into the flame. She opened her eyes wide and blew her mouth gently. As a result, CiCi blew gently and the flame went out. I wonder if the flame is enchanted again and only listens to her?
Why can't Hercules blow out the flame, but the small one can, because the big end of the funnel is facing the flame, and the blown airflow will spread in all directions, so it can't blow out the flame. The small end of the funnel faces the flame. When it is small, the airflow will gather together, so it can blow out the flame.
Through this experiment, I know that the world is full of mysteries, and we must be good at using our brains to solve these mysteries.
The Mystery of Life Composition 9 During the summer vacation, my mother took me to my grandmother's house. I am very happy, because I can see my small vegetable garden!
Grandma's home is in the country. In a small yard, there is an open space. Grandma keeps vegetables. In spring, grandma waters the vegetable fields, then scatters chicken manure and pig manure evenly in the fields, and then turns over the fields to sow. Before long, all kinds of vegetable seedlings showed their little heads and were crossed. At this time, grandma listened to the song with a tape recorder while loosening the soil and turned up the volume. I was impatient and was about to turn it off when grandma shouted; Don't turn off your phone. Xiao Xinwei is also listening to music. Look! How fast these little guys are growing now!
Grandma's words make me wonder. When I get home, I check the information online. It turns out that not only melons and fruits, but also many plants like listening to music! Beethoven's music can revive a withered rose or a withered radish. Under the same conditions, mimosa listening to music is more than twice as high as mimosa not listening to music. And the leaves and thorns are all covered. After listening to music, tomatoes grow big and sweet. After listening to the music "Blue Danube", corn and soybeans are full. ...
After checking the information, I couldn't wait for my mother to take me to my grandmother's house, and specially brought lettuce and cabbage seeds. We found an open space, sowed seeds, watered and fertilized regularly, expecting it to take root and sprout as soon as possible, and invited grandma to play classical music regularly during the period. Every week after that, I will go to my grandmother's house to see my small vegetable garden. Sure enough, these vegetables grow well and are greener than their neighbors!
I am very happy.
Facts are stranger than novels. Let's explore together, and we will discover more mysteries.

I tried it for a while after I finished, and my arm was a little tired. I had a rest and then went on working. After five or six minutes, the bag was flat. My mother flattened it and covered it with an air nozzle.
Mother said, "What has changed since the air was pumped out?" I opened my eyes wide and said, "What a change. Just now, the quilt was about seven or eight Chinese books thick, and now there are only three. Mom, it's amazing. "
It turns out that there are so many little mysteries in our lives.
