It's a little hot today. I want to eat ice cream. There is no ice cream at home, and my mother won't buy it for me. I thought about it and gave me a solution: I put yogurt in the refrigerator. After a night, I took it out, removed the outer packaging box and put it in the cup. I was eating there when my mother saw it and said strangely, "Who bought the ice cream?" I told my mom that I invented it. Mom said, "You are smart. Just use it in your studies." Want to invent again in the future?

Today, I want to make a small invention, but today is my grandfather's birthday, so I have to go to my hometown. At noon, grandma made a cup of milk tea for my brother and me. After drinking milk tea, I picked up my brother's milk tea cover and folded it with mine. I found that I could make a "cosmetic box". When I got home, I started to do it. I tried it once and found it difficult: the "eye shadow" could not fit in, and the "mirror" was missing three and four. Half an hour passed, and the cosmetic box was finally made.

As we all know, chopsticks are common kitchen utensils in life and can be used to hold things. But have you ever seen chopsticks made of plasticine? Today I'm going to make a pair of chopsticks with plasticine.

First, take out a can of plasticine, take out a yellow plasticine, evenly divide it into two halves, and rub the half into a cylinder, so that a pair of chopsticks is basically completed. Then rub it into a sharp point below, and then make a pair of chopsticks with red plasticine, so that a pair of chopsticks is ready.

Once, when my mother got on the bus, it was easy for thieves to do it because there were many people. When I got on the bus, my mother discovered that my mobile phone had been stolen. So I thought, can you invent a mobile phone bag with a password?

So, I started to make a mobile phone bag with a password. First, I chose black cloth as my mobile phone bag, put the password on it, and then hung it on my belt. You're screwed..

This kind of mobile phone bag can prevent theft, even if a thief sees it, it can't be opened because there is a password. Even if the thief knows the password, it is impossible to open it in a short time.

With my little invention, my mother's mobile phone won't be stolen. I like my invention.

I think if everyone uses my gizmo, then people's mobile phones will not be easily stolen by thieves. Doesn't this greatly promote the safety of our property?

Well, one thing I'm worried about is that there's no room for pens at home. Well, what should I do?

I thought and thought, and it suddenly occurred to me, didn't mom put a bucket of grass on the balcony? Didn't mom say it was useless? I'll give it a big makeover.

I put it in front of my eyes, put some paper in it and stick it on. I stuffed two plastic sheets in it, and then divided the bucket into four parts, one for pencils, one for pens, one for erasers, and the last for rulers. I drew a beautiful pattern on the outside of the pen container, put some lovely stickers and put a small book on it, so that my pen container was finished.

Is my pen container stick?

My little invention, Fan Wenqi.

Today, it began to rain in Mao Mao in Suichang County.

I made a little invention at home and invented a boat. I put the wooden board on the table first, then fix the plastic bottle on the wooden board with scotch tape, then stick the box on it, and then install other parts, and the boat is ready. I tried it in my own bathtub. This ship is too big to hold.

Oh, I have an idea. I made a big pool with a few screws and five big boards. I pour the water in and the big pool will be ready.

I put the boat on the surface of the big pool. Ah, it worked. After hard work, the ship can finally go upstream on the water.

My little invention is a model essay.

On Saturday afternoon, my mother and I made a small invention called the Infinite Corridor Landscape Box.

The materials to be prepared are: a piece of transparent paper, two flat mirrors, a picture of a long corridor and a box.

All right, let's get started. First, paste the prepared box, then paste the transparent paper on the left side of the box, then paste two flat mirrors on the box, one on the front and the other on the back, and paste the picture of the promenade in the middle, and the promenade landscape box is ready.

There is a small hole in the landscape box. If you look into the small hole, you will see an endless corridor. That's because under the illumination of light, the picture of the corridor is repeatedly reflected by two parallel plane mirrors to form multiple images, so it presents the effect of an infinite corridor.

I believe that if you do it yourself, you will work miracles!

Today, let me tell you a little invention of mine? My beloved racing model.

First, let me tell you how to make a racing model. First draw the shape of the racing car you want to make on a piece of cardboard, and then carefully cut out the model with scissors. Then use cardboard to make four wheels and car decorations. Finally, the wheels, decorations and the newly cut model are glued together, and the model is finished.

Now, you must be curious to know what my car model looks like. My car model is 06, because its color is almost white and it is very powerful, so I gave him a nice name, called "Blizzard". The decorations I installed for it are shield-shaped front and sickle-shaped back. The whole car is like a fierce bull. How's it going? I like it.

By making this car model, I also understand a truth: if you want to succeed in doing something, you must pay attention to methods, and at the same time, you must gradually cultivate your serious and patient attitude.

I invented a strange pencil box.

This pencil case is made of a special light metal. After special treatment, it is harder than steel and lighter than plastic, and will never rust. I installed four buttons in the pencil case, and the remote control device will automatically send the pen out of the pencil case without going to the pencil case to get it.

My pencil case is also equipped with a luminous board. If there is a power failure at night, just press the white button and the pencil case will emit soft light, just like during the day. It's so happy to study in this light.

My pencil case is also equipped with a small memory. This memory is small, but it can store many things, such as 300 ancient poems, Xinhua dictionary, and all courses from primary school to university. There is also a calculator in this pencil box.

The most important thing is that this pencil box has a communicator. The head teacher sitting in the office correcting homework can also see whether the students are serious in other teachers' classes.
