On the Composition Theme of Traditional Toy Making

Today, I made a small production by myself-table tennis match. As long as you turn the handle by hand, there will be two lively and lovely little boys playing table tennis, one for you and one for me. 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 cut a small transverse opening at both ends of the box cover, and cut a small round hole at the center of both ends of the carton. Then the thin wire is bent into a crankshaft according to the length of the carton, so that the bent part of the crankshaft is aligned with the two small holes on the box cover. Finally, cut out two people with rackets from cardboard and drill 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 with double-sided tape. Finally, draw clothes and facial features 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 learned it yesterday As soon as I heard 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." 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? Then I finally made a decision: of course I did. . I am reluctant to make this decision, because I really can'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 paper cup into the shape of a sunflower. My mother thought it had nothing to do with technology, and suddenly came up 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 a 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 mashed two eggs with chopsticks and tried to stick them on paper cups. However, the damn tape doesn't work when it reaches the water. I thought of tying it with a thread. As a result, I didn't finish watching it by school time, so I simply stopped playing. Pack your things. I'm going to school.

As soon as I came back from school, my father said, "Have you finished the small production?" I was "stuffy" on my head, and my father's words stabbed me in the face like a knife. "Not yet." "Let me make something for you!" I don't know what medicine dad sells in the gourd. "There is no prick the head of that kind of thing? There is also a candle. " "Oh, I'll show it to you later. Everything else needed for hand-made is on the coffee table. " Things are ready. I saw my father peel off the skin of a thick scalp rope, as long as the leather rope is inside. Then mysteriously said: "you go to do your homework first!" " I obeyed and went to do my homework. While doing my homework, I secretly glanced at him: I saw him cut off all the skin of the thick scalp rope, leaving only three rubber bands inside. Then he conveniently 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 so attracted that the pen scratched the corner of the clothes. At this time, my father actually accomplished those things without anyone knowing. 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 …" I didn't believe it at first. Then I turned the nail 10 times. The result tilted to one side and did not leave. Haha, now my father says, "No, the two sides are uneven …" Later, in exchange, he stared at the tip of my pencil. I looked at him and wanted to use it. I said generously. Hee hee, 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 a thing is round, and it can walk, but it can't walk for a long time. If it has power, it can walk for a long time. The "Yida xylitol" bottle is a cylinder, and the rubber band in it is like power, while the pencils and nails at both ends are used to keep balance, while the candles connected to the top "Yida xylitol" bottle play the role of lubricating oil, so that the pencils don't run away, but run away by themselves.

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

Look, my little production is ok. If you want to do it, please pay attention to the bending height of the crankshaft.

thank you
