My little invention composition 1
After class, the blackboard is full of piles of formulas. It seems that the blackboard cleaner will have to work hard again.
Every time you clean the blackboard, either a short person can't clean the top of the blackboard, or someone who can clean the chalk dust on the top is covered with chalk dust on his shoulders. What should I do? At this time, I set my eyes on the broom. Have an idea! I unscrewed the pole on the broom, and then asked someone to borrow a universal glue to stick the broom pole and the blackboard eraser together, thus becoming an extended version of the blackboard eraser.
My little invention has been praised by most people, and now short people can wipe chalk; And tall people can stand in the distance and wipe; With the extended version of the blackboard eraser, cleaning the blackboard is more interesting!
Unfortunately, the good times did not last long. Some people reported that it was easy and effortless to lengthen the top of the blackboard. Wipe your ass with a heavy stick when you can. After listening to this, I will immediately invent a faster blackboard eraser.
Finally, I invented a folding blackboard eraser. Lift the pole when it is high, and put it in when it is low. In fact, the folding rod is just a telescopic pointer, and then stick it on.
Because a small blackboard eraser and a small invention have brought us convenience.
My little invention composition II
This afternoon, I found that my nails were very long, so I decided to cut them. This is the first time I cut my nails myself. Holding a nail clipper in my hand, I carefully began to cut my nails. But the cut nails fell everywhere, on the ground, on the table and on the chair. I find it not difficult to cut my nails, but it is very troublesome to tidy them up after cutting.
Is there a nail clipper that can collect nails while cutting them? Just like the pencil sharpener we use to roll pencils, we can collect pencil scraps in containers while rolling pencils.
Considering that nails will fall off under the action of gravity, I thought about the materials that can be used at home and decided to tie a small plastic bag under the nail clippers to collect nails in time. The first nail clipper I invented was successfully made, and my father decided to try it first. But my father's nails are harder than mine. When I cut them with nail clippers, my nails jumped in all directions, up, down, left and right, but they didn't fall into the bag immediately.
It seems that nail clippers that can collect nails need not only a container that can collect nails in time, but also a protective cover that can stop nails from jumping, and it should be transparent and not hinder people's sight of cutting nails. The materials available at home are too limited, and I'm still thinking.

I went to a bar in Beijing last night and took off my coat, but it was very hot because it was not convenient to take off my long pants. So I came up with a little invention? Pants that come off easily.
It's simple. The trousers are brushed on both sides. As long as the sides are pulled down, it is easy to take them off and wear them. Because it is cold outside and warm inside in winter in the north, you need to take off your clothes when you enter the house, but it is not convenient to take off your long pants, woolen pants and cotton pants when you wear them inside, so the pants that are easy to take off outside can be made into leather pants, jeans, khaki casual pants and cotton pants. Of course, the style of trousers can also be designed in fashion to meet the needs of various consumers.
There's another little invention that I've been thinking about for years? Charging warm shoes, many provinces and cities in the south of the Yangtze River don't have heating in winter, so many people will freeze their feet even if they wear cotton shoes and wool shoes, especially children. When their feet are cold, they will be cold all over. Of course, this kind of shoes should also sell well in the north. 10 years ago, when I was studying in Sichuan, I thought it would be nice to have a pair of shoes that could heat up. It seems that I haven't seen this kind of shoes for so many years. I don't know if the storage capacity of rechargeable batteries can produce rechargeable warm shoes now. Install two rechargeable batteries on the sole, and keep the sole at a constant temperature of more than 20 degrees. It is best to adjust the temperature of the sole yourself. So as not to freeze your feet. Of course, this invention requires repeated experiments by manufacturers of rechargeable batteries, such as how long the sole can keep constant temperature after charging. I think the temperature may be kept above 10 15, so that the feet may not freeze. Of course, the higher the temperature, the more power consumption, and the battery will soon be dead.
I love thinking about these small inventions, but I often just think about them for a long time, but I can't make them myself, so I hope I can show them to relevant manufacturers and produce them for the benefit of those in need.
My little invention composition four
Recently, the environment in the city is getting worse and worse, and garbage can be seen everywhere. In order to protect the environment, I used more than 1000 materials and racked my brains to finally invent an environmental protection robot.
My robot is called a sweeper. Its functions are all about environmental protection. Although it is only 130 cm high, it has numerous functions. If it sees someone throwing rubbish, it will go forward to educate the litterer. If it sees garbage, it will quickly judge whether the garbage can be recycled. If it is recyclable, it will turn the garbage into new ones and send them back to the store. If it is not recyclable, just dispose of the garbage. The most amazing thing is that if it meets someone who throws garbage to destroy the environment and doesn't listen to advice, it will hit someone, beat him to the ground, and finally make him recite 1000 times "environmental protection instructions". Maybe you will say: Why does your robot only know how to educate others and have no other skills? That's true. If it sees someone bending over to pick up garbage, it will take the initiative to award an environmental protection award to this person who cares for the environment and send him an "Environmental Protection Handbook" to keep him in a good habit of caring for the environment.
I think, the world is so big, how can only one sweeper be enough? So, I cloned many small cleaners. I also applied for an invention patent, and environmental protection companies and 10 primary and secondary schools all over the world snapped up my products. Soon, my little invention was robbed.
I will certainly invent more things to benefit the country and the people in the future.
My little invention composition five
Once, my family traveled to Putuo Mountain and arrived in Ningbo. I found several small windmills spinning on the top of the telephone pole beside the road. I asked my mother curiously: Why is there a small windmill turning on the telephone pole? My mother told me that the worker's uncle used wind power to generate electricity. At that time, I had a little knowledge, and later I learned about air and wind in extracurricular books: wind can make sailboats sail on the sea; Turn the windmill and divert water to irrigate farmland. I also know that many advanced countries in the world use wind power to generate electricity, save resources and protect the environment. So, I think if I can invent a car with sails, then this car can go forward by the wind, and this car will never need to refuel and will never pollute the air with carbon dioxide.
With the help of my father, I first found cardboard to make a big windmill, then fixed the windmill on one section of the stick with iron wire, and finally fixed the other end of the stick on the toy car. I came to the open space of the community with my works. Just when a gust of wind blew, the windmill turned very fast and the car drove slowly forward. Haha, my little invention, the environmental protection windmill, is finished. Dad told me that we should try our best to store the wind for use when there is no wind.
I believe that in the near future, there will be a car with sails on the street. Children, you must remember that it was invented by a child named Pan.
