Chapter 503 Busy Taking advantage of the east wind to release paper kites (13)

The grass grows and the warbler flies in February, and the willows are drunk in the spring.

The children came back early from school, busy taking advantage of the east wind to release paper kites.

It was only when Zhang Feng saw a kite floating at the entrance of the village by accident that he realized that it was the kite-flying season of the year again.

At this time, a few tourists were flying kites on the river beach. They seemed to be a family of three. They felt very warm and happy. Thinking about when they were young, the friends had no money to buy kites, so they used bamboo strips, newspapers, paste and other tools and materials to tie them together. Kites, although very few successfully fly, but the friends are still very happy.

Thinking of this, Zhang Feng also had the urge to make a kite himself.

I hurried home, rummaged through the utility room, and found utility knives, bamboo slices, and white cotton paper. These were the tools and materials used to make kites when I was a child.

What if there is no paste? ?

Then use flour to make it yourself, pour the white flour into the teacup, then flush with water and stir, and finally put it on the induction cooker to boil for a while, keep stirring, if it feels sticky, then it's done.

"Crazy brother, what are you doing?" After school, the little guy ran into the yard, saw Zhang Feng was cutting bamboo strips, bent down, and asked curiously.

"Guess what I'm doing?" Zhang Feng asked with a smile.

"Hee hee, I know you are making kites, madman, aren't you?" The little guy was very clever, and when he saw the other tools on the ground, he replied with a smile.

"Yes, how did you know?" Zhang Feng asked curiously.

"Hee hee, I just saw Brother Tie Dan doing it yesterday!!" The little guy said triumphantly.

"Crazy brother, why did the kite fly into the sky??"

"Because the wind has the power of the wind! When the wind blows, don't the leaves on the ground be blown around?"

The little guy nodded silently, as if he understood, but he didn't seem to understand very well.

"Crazy brother, why did the plane fly into the sky?? Is it also blown by the wind??" The curious baby asked again.

"Haha, how is that possible? How could the heavy plane be blown into the sky by the wind??" Zhang Feng laughed.

"Why is that?" The little guy broke the casserole and asked the end.

"It's very complicated. When you go to middle school, you'll know when you learn physics!!"

The little guy counted with his fingers, one, two, three... Then he frowned and said in distress: "Oh, it will take a long time!!"

In fact, the flight of an airplane relies on aerodynamic force, which is different from that of a balloon or a balloon-like airship that relies on air buoyancy.Balloons and airships are lifted up by the upward buoyancy of the air because the specific gravity of the gas in them is different from that of the air, which is smaller than the specific gravity of the air.

However, the specific gravity of an airplane is much larger than that of air. Compared with an airplane, the density of air is so small that it can only provide very small buoyancy. A stationary airplane cannot fly.

However, if an aircraft is propelled in the air, it can only fly off the ground when it reaches a certain speed and other conditions. Even a helicopter relies on aerodynamic force, which means that the rotor rotates to a certain speed and reaches a certain lift. lift off.

Therefore, the flight principle of an airplane involves relatively complicated aerodynamics. Even in junior high and high school, it is just a little popular science. If you want to study professionally, you must go to university to choose a related major.

After a few bangs, Zhang Feng rested a bamboo strip.

The kite made by Zhang Feng is the simplest rectangular kite. Four bamboo strips are tied to form a king character, and then pasted with white cotton paper. After the paste is dry, thread is put on. A simple kite is completed.

"Wow! Madman, let's fly a kite at the entrance of the village, shall we?" The little guy shouted excitedly when he saw the completed kite in Zhang Feng's hand.

"Don't be too busy, wait until I find some white threads."

A lot of white thread is needed to fly a kite. Fortunately, there is a lot of white thread left on the soles of my mother's shoes. Zhang Feng tried it and it is very strong, which can be used as a kite thread.

Those who are fastidious will also make a special kite string rotor, but Zhang Feng can't wait that long, and doesn't want to be so troublesome, just use a chopstick to wind the white string on it.

"Let's go! Let's fly the kite..." The little duck happily followed Zhang Feng and ran to the river beach. His excited appearance was so cute.

"Little duck, Brother Crazy, wait for us..."

Seeing Zhang Feng and the little duck holding the kite, Da Mao and the little guys threw down the broken bricks and tiles of the house in their hands, and chased after them.

"Hehe, what a kid!!" Zhang Mu, Wang Guilan, smiled and shook her head when she saw it. She didn't know whether she was talking about the duckling or her own son, and her eyes were full of smiles.

…………

"Hey! Xiaofeng is going to fly a kite? And with such a large group of children."

Aunt Gui Lian was resting in the square and asked with a smile when she saw a group of little kids behind Zhang Feng's butt.

"Hehe, won't you be idle? Just make a kite for fun!!"

Zhang Feng smiled shyly, and hurried away after speaking.

Seeing Zhang Feng fleeing in embarrassment, the women at the entrance of the village burst into laughter, thinking it was really interesting.

The little kids didn't know why and laughed, Zhang Feng couldn't help wiping his sweat,
"Hehe, Xiaofeng is really, such a big man, he still plays kites!" Aunt Guilian said with a smile.

"What's the matter?? Look at the river beach, most of the kite-flying adults are adults!" Aunt Dashan said with a smile.

"This is also..."

If it was in the city, it would be normal for adults to fly kites, but in the countryside, kites are children's toys, and no one for adults plays with them. Once everyone saw Zhang Feng flying a kite, it was very novel.

…………

"The wind is coming, get out of the way!"

Zhang Feng chased away the little kids who were following him, picked up the kite, and ran towards it. The kite went up against the wind, and flew high into the sky in a blink of an eye.

While running, Zhang Feng let out the string, and the kite flew higher and higher, farther and farther.

"Wow! Flying up, the lunatic brother is flying up..."

"Ah, flying so high..."

When the little ones saw it, they screamed excitedly and jumped up and down, as if it wasn't Zhang Feng who was flying the kite, but themselves, and they were very excited.

Feeling that the kite has been flying smoothly, Zhang Feng also stopped, and slowly let the kite fly higher, because only in higher places, the wind will be stronger and last longer. Only in this way can the kite be more stable and stay It will not fall from the sky for a long time.

"Crazy brother, your kite flies so high!!" Looking up at the kite in the sky, Xiao Shitou said to Zhang Feng with admiration.

"Crazy brother, did you make this kite yourself?" Da Mao asked curiously.

"Of course, I just saw Brother Crazy do it with my own eyes!!" The duckling said triumphantly.

"Wow! Crazy brother, you are really amazing!!" After the little guys knew that Zhang Feng made the kite, they were all in admiration.

"Oh, if only I could also make kites!!" Seeing the tall kites flying in the sky, Xiao Shitou said enviously.

This sentence seemed to express the hearts of the little guys, and everyone looked at Zhang Feng with envy and longing.
