every time I visit my relatives in the new year, my mother is always extremely worried. Because there are too many people coming, wearing slippers is too troublesome; Don't wear it, just come in with your shoes on, it's too dirty and it's too much trouble to do cleaning. The family has a headache for this. Look! There will be another guest tomorrow! What should I do! It's mom and dad talking about it again.

mom said, "alas! So many guests, how many slippers! " Dad said, "Give out the shoe covers!" "A lot of people are standing there waiting for shoe covers. How embarrassing!" Mom said at once.

after listening to my parents' words, I fell into deep thought: it would be nice if there was something that was not as troublesome as shoe covers and could separate dirty soles. Thus, the first small invention of my life began.

First of all, I took two sheets of plastic sheets for electrical appliances, cut two insoles the size of 36 yards of shoes, and then stuck two pieces of double-sided tape on the upper and lower arcs. Uncover the smooth sticker on it, and a pair of dirty insoles will be finished.

I pulled my mother over, put her on the shoes for going out, and then stepped on my insole. "Mom, take a few steps." I ordered. Mom took a few steps slowly, and the front was stuck, but what about the back? Because it is a high-heeled shoe, the heel is very small, and my mother's heel is not bonded with the adhesive at the back, so it is inconvenient to walk, and it is easy to fall off and not strong enough.

hey! Got it. I picked up the double-sided adhesive tape and covered all the back parts. When my mother put it on again, it stuck. My mother walked back and forth at home wearing the insole I made, feeling comfortable and firm.

"I succeeded!" I am dancing happily in the living room. Mom and dad finally started to frown, revealing a long-lost smile. Our family started construction, and in a short time, 3 pairs of insoles were ready.

Dad touched my head and smiled and said, "My daughter is really capable. This insole is not only convenient, but also simple to make and environmentally friendly. Well, it really helped me a lot! "

article 2: my invention "multifunctional pen"

with the growth of age, I found that there are more and more nearsighted students in our class! I have an indescribable taste in my heart. How sad!

after several months' observation, I finally found out that the reason for my classmates' myopia is the wrong sitting posture.

Later, I invented a multifunctional pen. This multifunctional pen is made of aluminum alloy, which is very light, so your hands won't get numb when you do your homework! Although its shape is the same as that of an ordinary pen, I tell you it has many functions! There are five buttons on the shaft of this pen. The first red button is a pencil. The second pink button is a pen; The third purple button is an eraser; The fourth green button is correction fluid; The fifth is the blue button.

As long as you are sitting incorrectly, it will prevent you from writing. With this pen, you can save a lot of time and money. Because it doesn't need you to refill the

pencil or ink the pen. Eraser and correction fluid are infinite, and no matter how you use them, you can't use them all.

after listening to my introduction, do you want to buy it? I'm telling you, it's not expensive for fifty cents. This pen is cheap!

The "multifunctional pen" was robbed within one minute after it arrived at the supermarket. I like my invention. If you have any good inventions, let's share them!

Chapter III: My Little Invention

In today's society, men buy cigarettes, send cigarettes and smoke all symbolize status and money. They get together, chat and smoke, which makes the house smoky and the air seriously polluted. My dad is no exception. I don't know how many cigarettes I have to smoke a day without my mother's control. I was determined to stop them.

I remember when I was a child, I put a signboard of "NO SMOKING" on the wall and specially set up a "special smoking room-home W.C.". But my uncle looked at the door countless times and was indifferent, so he smoked. Although I will push them into "W.C." when I see them, they just deal with me a little and put out the cigarette. Every time I walk out of the "W.C." and turn around, they light another one. Then when I see it, I will do it again and again. Adults follow me tirelessly, as if they were playing with children. Finally, I got bored first and "gave up". They may be secretly pleased or surprised by their patience. As a result, wherever there is smoke, there is always a strong and pungent smell of smoke, which permeates the air ... < P > Smoking has four major hazards: 1. It is harmful to health; 2. pollute the environment; 3 fire hazards; 4 damage family harmony. Therefore, in view of the above four points, I designed an item: the coat of cigarettes-the cigarette shell. It is a special plexiglass (ultra-thin) combined with some chemical substances, which requires heat resistance, fire resistance and no deformation. The invention comprises the following steps: the cigarette case consists of two parts: a cigarette case base and a cigarette case tube.

First of all, we light the cigarette. We can light the cigarette by opening the base and the cigarette case tube. Then, the base is closed, so that the soot is gathered on the base, thus reducing the garbage. You will ask me, is there air in the cigarette case, how can the cigarette burn? The secret is hidden in the upper part of the cigarette case. The cigarette pipe is designed as a needle-tip mesh for air to enter and exit ... When the cigarette is finished, just press the cigarette butt into the cigarette pipe and it will naturally go out.

how about it? Is my invention good?

article 4: my gizmo

last week, the teacher assigned us a small task, that is, to make a small work with waste materials. The teacher said to us, "I believe the students will do better than one!" After class, my classmates asked me, "Wu Ruo Iridium, what are you going to do?" I smiled and said, "I haven't decided yet?"

when I got home from school in the afternoon, I finished my homework quickly and racked my brains to think of it ... what should I do? When my mind was in a mess, the rags my grandmother put by the bed inspired me suddenly, so I asked my grandmother for some different colors of cloth. My grandmother looked at me suspiciously. "What do you want with these cloths?" "You'll know when I finish my little production," I said with a smile. I think I can do it!

First of all, I entered the preparation stage. I cut the outline of the doll's head, body and clothes with scissors, braided my hair with curly wool, prepared earrings, necklaces and headdresses for decoration, as well as needles and threads, and got everything ready for the preparation. Then I entered the sewing stage. At first, I always sewed the needle in the wrong position, and occasionally pricked my finger, but gradually the needle and thread became more and more familiar with me, and I quickly finished sewing the doll's body and clothes. Finally, in the decoration stage, I sewed bright eyes and bright red lips on the doll and decorated it with prepared earrings, necklaces and hair. Haha, a perfect work of art was born!

By making dolls, I know that waste can also be turned into a treasure that I can't put down! I think, please join me in striving to be a "little guardian of environmental protection"!

article 5: my scientific gizmo

in our daily life, we always find some small problems, a small discovery and a small invention. Science can always help us a lot, so I made a scientific gizmo, which is both simple and useful.

I remember that time, during the summer vacation, the teacher gave us an assignment of scientific gizmos. One month before the summer vacation, I started my own gizmos. What should I do? I think about it, ah! Got it. Make a plastic bottle yacht. Great! Finally figured it out. It's a plastic bottle yacht, but it's actually made of plastic bottles, popsicles and cards, which is very simple and convenient. In this way, I picked up an old plastic bottle at home, carefully pounded it up, cut off a small piece of it, made a mirror with two lenses by reflection, tied a cowhide tendon on the bottle cap, and tied two popsicles on both sides. Use cardboard to make a little decoration, bright and bright, more prominent. It's easy to say, but it's not easy to do. When cutting bottles, I always cut them out. I use periscope to connect the bottles, so I can see the yacht's condition in the water in time. When I turn the popsicles on both sides, it will generate thrust to make the yacht move forward. But I want it to go up and down. By the way, the teacher has done submarine experiments in class. I can make a diving cabin to hold water and make a hand-held manipulator and install it on the yacht. This is perfect. I turned the popsicles on both sides and filled them with water. As soon as I let go, the yacht swam automatically. I saw it moving in the water through the mirror. It was amazing! Science made me feel that doing experiments was so wonderful, and I fell in love with science.

This is my scientific gizmo, an ordinary gizmo. This simple experiment makes me feel extremely happy. This is the happiness of science, and let me know that science is around.

article 6: gizmos

turning over a few pages of newspapers, I suddenly saw an exciting news "Sewing a chip in a football", which wrote: In order to make the game more fair, a German engineer sewed a chip in a football. During the game, if the chip found that the judge had misjudged or whistled, it would make a harsh noise. If in a football match, the misjudgment and black whistle behavior exceed the number of times stipulated by the Football Association, it will be punished.

reading this, I can't help thinking of my aunt. Once, when my aunt and I went shopping in Hongyun Computer City, our wallets were stolen. Not only could we not buy anything, but even some credit card ID cards were missing. I still remember the way my aunt ran up and down when she went to report the loss. At this moment, it occurred to me that what would happen if I sewed the chip in my wallet? I fantasize about what this wallet looks like. By the way, this wallet is bright in color and thin, and people like it at first sight. This wallet has four functions. First, if someone steals it, he will make a loud cry to make others aware and catch the thief. Second, if the thief can't be caught, the wallet will automatically open the camera and call the police, and put down the small tracker that has already been prepared on the thief, and then automatically call the police. Third, if the thief who steals the wallet does something illegal, such as taking drugs, the wallet will give all the information to the police to assist in the investigation. Fourth, if you leave your wallet somewhere, he will dial your mobile phone and say with a pre-recorded recording, "Where did you leave your wallet?" If you don't get it within a month, it will put itself in the trash can. Do you think this wallet will become a popular wallet in the future? I believe that in the future, everyone will have this kind of wallet in their hands.

I must study hard and invent this kind of wallet in the near future. To tell you, I have given this kind of wallet a name: Chip Wallet. My invention composition 4 words article 7: Water-saving invention

Didi, Didi, Didi, this is the hundredth (omitting N O's) "annoying" sound, and it wastes tons of water in my house, which is really annoying.

For this reason, my father runs every day, and today he goes to ask someone to help him look at it, and tomorrow it will break down again. I thought: the clock can ring by itself without being controlled by others. There must be a mystery in it. After thinking hard for a while, I decided to disassemble it, but I found nothing, but my mother scolded me. After this time, I decided to invent a small machine to install it on the tap ...

"Copper, iron, knife, small drill, etc. I decided to go all out.

I put the copper and iron pieces together, drilled four small holes in them with a small drill, then stuck the copper and iron pieces together with 52 glue, cut off the original piece under the original faucet with a knife, and stuck the newly assembled gadget with 52 glue. As a result, the water was still dripping and dripping. I took it down again and made some small "means". I told my parents the good news, and they all said that there was an inventor in our house! At this time, praise rained on me.

I proudly looked at my "trophy" and thought: The first masterpiece of this little scientist, the water-saving small machine, was born.

although my invention failed at first, I finally succeeded after repeated modifications. This is called "how can you see a rainbow without wind and rain"!
