(additional update for Li Goudan, Class 2, 3rd Year)

"Xiqian, what are you doing?" At this time, Chen Dabao's son Chen Haoxuan said curiously when he saw that Xiqian seemed to have done it.

"Paper airplane!" Qianxi replied.

"Hey, what did I think it is? We have made paper airplanes in class. My father made kites for me, and they could fly very high." Chen Haoxuan said proudly, his words full of superiority.

But Chen Dabao was not so easy at this time. He bought the materials online. Although there was an instruction manual, he was clumsy at this time. He couldn't understand these complicated materials even after the instruction manual.

"I made it myself. Susu said it could fly for a long time. We have two of them, which are different from what we did in class." Xixi said.

"I don't look special about the plane you made in Xixi." Xiao Qingxi also walked over and said.

Xiao Qingxi's mother smiled apologized, but she also seemed to think that Su Chen was a little perfunctory. She folded a paper plane and guessed that Su Chen was the only one who was so perfunctory in the audience.

Xixi was a little sad when people said it, and Su Chen quickly comforted her, "Xixi, let's go outside to fly and see. The plane is for flying, not for watching."

"Yes!" Xixi ignored them and walked out of the classroom with her paper plane.

Chen Haoxuan and Xiao Qingxi followed, Zhu Siyao and Li Jingyi also walked out of the classroom to see Qianxi's works. When the other children saw that the teachers had come out, they all followed curiously.

"Is Su Su flying here?" asked Xixi when she walked to the empty playground.

"Well, it's here." Su Chen smiled, Su Chen was very confident in his paper plane.

However, just when Qianxi was about to throw the plane, she was stopped by Su Chen, "It was not thrown like this. Look, I will demonstrate it to you."

After saying that, Su Chen picked up the paper plane he had folded, held the phone in his right hand, breathed a sigh of relief, and squatted slowly. When he squatted to the deepest point, he suddenly exerted force and jumped up, throwing the plane out with an angle greater than 60 degrees.

The paper plane soared into the air. At first, the plane was no different, but it seemed that when the plane was about to fall, the plane hovered and flew up again.

Five seconds passed, the plane was still flying, ten seconds passed, the plane was still flying, fifteen seconds passed, and the plane did not mean to fall.

"Wow. This plane has been flying for a long time!"

"This plane is so amazing!"

"It's still flying!"

The plane kept hovering and flying, and it took about twenty seconds before the plane slowly landed.

The children present widened their eyes, and even teachers like Zhu Siyao were a little surprised.

After all, the paper plane they folded usually falls in just a few seconds, so how could they fly like Su Chen for nearly half a minute?

"I want to fly, I want to fly!" Qianxi could no longer hold back when she saw the plane was so powerful.

"Okay!" Su Chen picked up his paper plane, and then saw Xixi flying. Xixi picked up the plane she had folded and acted to fly. She slowly squatted down as Su Chen looked like she was.

"Wait a minute." Su Chen stopped.

"What's wrong?" Xixi was puzzled.

"Before flying, my mouth breathed a sigh of relief at the plane!" Su Chen said.

Before flying, he breathed a sigh of relief at the plane. This was the soul action of the flying paper plane. Without it, Su Chen felt that it was imperfect.

In fact, from a physical perspective, the head of a paper aircraft is small, which can reduce drag, but also makes the head too light and the fuselage quality uneven.

According to aerodynamics, take a breath first, and the wet airplane head is slightly heavier, which can keep the fuselage in balance as a whole, and the heating head can also allow paper planes to fly in the air for a long time.

However, Su Chen would not explain these things to Xixi, and she couldn't understand them either.

After hearing Su Chen's experience, Qianxi breathed a sigh of relief at the plane, and she was full of expectations. She learned from Su Chen's actions and threw the paper plane out. However, Qianxi's strength was a little weak, and the plane only flew for about ten seconds.

But it has been much longer than they usually flew.

"Dad, I want a paper plane, too."

"Mom, I want to fold that kind of paper plane, too." At this time, more and more children were watching, and many of them were even clamoring to fold.

At this time, a middle-aged man walked towards Su Chen, "Hello, I am Chu Mo's father."

"Hello." Su Chen smiled, muttering in his heart why he looked different from on TV.

"Can you ask how to fold that paper plane? My daughter wants to learn it." Dad Xiong pointed to Xiong Chumo, who was looking brightly beside him, and said.

Su Chen glanced at Xixi. Xixi was currently surrounded by children in the class to ask about how to fold the plane.

The children who just disregarded this have become enthusiastic fans of this paper plane.

The parents who thought Su Chen was perfunctory to their children were now admired by Su Chen.

Don’t look at a small paper plane, there is a lot of knowledge here.

None of the parents present had never played with paper airplanes. It was because they had all played with paper airplanes that they knew how amazing it would be to let a paper airplane fly in the air for more than twenty seconds.

Su Chen just used physics knowledge to enhance the air stagnation performance of paper aircraft. The scientific name of paper aircraft is originally: the physical model of autonomous aerodynamics.

As the saying goes, the world is full of knowledge. Who would have thought that a small paper plane would use aerodynamic knowledge?

Because of a test flight of the plane, Xixi became a sensational figure in the school. Now Xixi is busy explaining to all her friends how to fold the plane.

Some parents who were embarrassed to squeeze into the group of children also came to Su Chen to ask for advice on how to fold the plane, and Su Chen also taught generously.

Finally, because there were too many people to learn, Su Chen decided to teach this method to the teachers in the school and then let the teachers demonstrate to the students in the classroom.

A handicraft parent-child activity has become an origami airplane activity because of Su Chen's appearance.

Happy times are always fast. When the parent meeting ends, the parents leave with their children, but Su Chen and Xixi squat in a fence.

Because Qianxi was so excited when she threw away the paper plane, she threw away all the car keys that Su Chen had played with for her before.

The place where the car keys fell was just outside the fence of the kindergarten. The other side of the fence seemed to be a yard, and I don’t know what it was for.

Su Chen was holding a branch and picking up the car keys, while Qianqian was squatting beside him to cheer Su Chen on.

Li Jingyi saw Su Chen and Qianqian in the fence behind the school and walked over curiously.

Then Li Jingyi saw Su Chen picking the car keys.

The stick was not long enough, and Su Chen had already reached the longest, and it was almost enough. Su Chen pushed the stick in his hand a little bit to increase the length of the stick, but the handle was too short and the place where the force was too small, so the stick fell directly outside the fence.

Seeing this, Li Jingyi was about to go to the utility room to bring a broom to Su Chen to flirt.

But at this time, Qianqian easily passed through the fence with her body, ran outside the wall and picked up the stick that Su Chen had just dropped and returned it to Su Chen, and then continued to squat beside her and watched Su Chen pick up the key.

"Thank you!" Su Chen took the stick and said thank you, ready to continue flirting, but he felt something was wrong.

"Puchi." At this time, Li Jingyi behind her laughed out loud.

Su Chen also suddenly realized that if Qianxi could get through, why would she be flirting with her? Just let Qianxi go over and pick it up directly.
