Today, I made a small production by myself-table tennis match. As long as the handle is turned by hand, two lively and lovely boys can play table tennis. It's really hard to tell the winner.

The table tennis table is made of a rectangular paper box. I'll open the carton first and fold it outward along the crease. Then I cut a small transverse hole at both ends of the box cover and a small round hole at the center of both ends of the box. Then I bent the thin wire into a crankshaft according to the length of the carton, so that the bend of the crankshaft was aligned with the two small holes on the lid. Finally, I cut it with cardboard into two people holding rackets and drilling a small hole in their feet.

When installing, I first put two people through two transverse holes in the box cover, then put the crankshaft through the holes in their feet, then close the box and stick it firmly on the back. Finally, I drew clothes and five senses on people. On Monday, our school announced the important things this week: making scientific and technological inventions and making small things! God, I'm afraid of technology! When I mention technology, I think of Shenzhou VII: solar panels, rockets, return capsules ... I can't think of anything. Although I am one of the best in science in my class, when it comes to invention, my mind is blank.

I didn't go to school because I was ill, so I didn't know the task in advance. I just found out yesterday. Hearing this word, I was anxious, and my hair was broken (not scared). As soon as I got home at noon yesterday, I said gloomily, "Mom, I'm going to do something at noon today, so don't bother!" " After dinner, I quickly took out paper cups, nails, iron sheets, table tennis, tape and other materials to prepare. But when I was finally ready to sit down, my mind was blank: what should I do? What does it feel like to make it? ..... After thinking about it, I actually thought: Do you want to do it or not? Later, I finally made a decision: of course I did. I was a little reluctant to make this decision because I really couldn't figure out what to do, not even gadgets. I was fiddling with two paper cups when I suddenly remembered the sunflower I had made before. So, I carefully cut the shape of sunflower from the paper cup. Just thinking that it had nothing to do with technology, my mother suddenly came over and said, "Tribal tiger, I made a beautiful windmill!" " I feel dizzy. I've never seen a pig run away after eating pork! In this way, a paper cup was scrapped in my hand. I tried to tie the ping-pong ball to a paper cup and let it float on the water, like a boat … Yes, this is simple! I played table tennis three or two times, but I found a new problem, the paper cup fell off! But it doesn't bother me. Eggshells are also "table tennis"! I "quickly" mashed two eggs with chopsticks and tried to stick them on paper cups. But the hateful tape didn't work when it was in the water, so I thought of tying it with thread. As a result, I didn't get ready until after school, so I just stopped playing. I packed my things and went to school.

As soon as I came back from school, my father said, "Have you finished the small production?" I was "annoyed" on my head, and my father's words stuck in my face like a knife. "Not yet." "Let me make something for you!" I don't know what medicine dad sells in the gourd. "Is there anything sticking to his head?" And a candle. ""Oh, I'll get it for you later. Everything else necessary for manual work is on the coffee table. "When things were ready, I saw my father take off the skin of a thick scalp rope, which was just a leather rope. Then mysteriously said: "You do your homework first! "I am very obedient, darling to do my homework. While doing my homework, I secretly glanced at him: I saw him cut off all the skins of the thick scalp rope, leaving only three rubber bands inside. Then he picked up the plastic box of "Yida xylitol" next to him, opened the lid and poured out all the sugar inside, and opened a hole in the top and bottom of the box with scissors ... I was fascinated. Even the pen scratched a corner of the clothes. At this time, my father actually finished it unnoticed. I saw that this thing is made of "Yida xylitol", with a flat bottom in the middle, a small nail on one side and a big nail on the other. Dad amplified his voice this time: "Turn the nail and it will run forward ..." At first, I didn't believe it. Later, I turned the nail 10 times and turned it askew. Now my father said, "No, the sides are uneven ..." Later, in exchange, he stared at the tip of my pencil. I looked at him and said generously, "Take it! "This job has made me a good person! When I put the pencil tip on the "Yida xylitol" bottle, I turned the pencil again. This little thing really ran away, sometimes fast, sometimes slow … what fun! Later, I heard my father tell me the principle of this little thing. I understood that an object is round, but it can walk for a long time. If it has power, it can walk for a long time. The "Yida Xylitol" bottle is a cylinder, the rubber band inside is like power, and the pencils and nails at both ends are candles connected to the "Yida Xylitol" bottle for balance.

In this way, my scientific and technological invention ended in success. Later, I named my father and I's little production "Carousel". The smallest thing is so important in our hearts. I believe that the merry-go-round will keep spinning in my heart. ...

You see, my little production is ok. If so, please pay attention to the bending height of the crankshaft.
