No spectator is ever innocent, every bystander is an accomplice.
Chen Xingtian took the rocket out of the utility room in full view of everyone. Then a large group of people were curious about what was inside and ran in to check. Unfortunately, there was nothing.
When he returned to the playground again, the rocket launch site was already packed, but everyone present consciously made way for him.
Among these people, everyone from Class 3 was present, and teachers from various subjects also came to join in the fun. Even half of the people from Experimental Class 4 came, including Wang Xin and Chang Qiuyue.
Some of them came to watch the rocket show, some came to eat without knowing the truth, and some came to place bets after learning about the bet between Chen Xingtian and Zuo Qingxuan.
When Zuo Qingxuan saw the rocket he was holding, he couldn't help but be stunned for a moment. The craftsmanship was almost the same as hers.
The iron-silver appearance exudes a serious atmosphere, and the smooth reflective surface shows how superb the craftsmanship of the case is.
A length of more than 1 meter indicates that it contains a large amount of instruments or fuel.
The ferocious jet port shows that it has terrifying propulsion power, enough to crush all the rockets present.
There are also four bloated brackets, which seem to contain some things, but I don’t know what they are used for.
Zuo Qingxuan did prepare exhibits for all projects, including model airplanes, perpetual motion machines, and rockets, just to prevent the bet from being invalidated due to different evaluation standards for different projects.
Chen Xingtian wisely did not choose other projects because their scoring criteria were very subjective.
Just like a perpetual motion machine, it's impossible to wait a few years to see who runs better. The day lilies are already cold.
Secondly, the upper limit of these exhibits is not high. Although the aircraft models are good, no matter how gorgeous the design is, there are only a few kinds of materials and the performance is just that. It is impossible to judge clearly.
He looked at Zuo Qingxuan's rocket. It was also very beautifully made, but the body was a little smaller, only about 8 decimeters long.
But the advantage is obvious. She uses a body made of titanium alloy material. The advantage of this material is that it is light and strong. In rocket launch projects, lightness is the biggest advantage.
The biggest unfairness of this kind of science and technology festival exhibits is that the materials can come from outside, but the assembly must be done by yourself.
This results in some students from good families having wider connections and more power to mobilize.
Zuo Qingxuan was born at the starting line. Her parents could easily get some suitable titanium alloy materials by contacting some aerospace materials companies.
In addition, she is a top student herself. She only needs to list the types and shapes of materials in drawings, and then she can send them directly to the manufacturer and send back the finished materials.
Chen Xingtian didn't have as many connections as she did, and he didn't have the advantage in terms of materials. Even the fuel had to be obtained with a lot of hard work. Fortunately, he knew how to seize every opportunity and take advantage of it.
"The two of us stayed until the end to compete, so as not to take away all the limelight from others."
"good."
…
The first thing to be launched was the water rocket made by the junior high school group.
The principle is very simple, just find two large bottles of Sprite or Coke, pour a certain amount of water into them, and plug the bottle mouths with rubber stoppers.
You need to prepare a pump during the competition. If the air tightness of the bottle is good and the stopper is tight enough, you can inject more air into it and fly into the air when the air pressure reaches the critical point.
This kind of rocket can be made at will by anyone who knows how to make it. It is easy to get started and the upper limit is low.
As soon as the game time came, the juniors and juniors began to pump gas into the rocket, and the scene was once joyful and interesting.
"come on! Come on!"
"Gas up! Gas up!"
"Please, inflate more, and fly high!"
"Pfft hahaha, look, Li Yang's Coke bottle is leaking."
A group of people looked in one direction and saw a boy with a crew cut anxiously re-corking the bottle and refilling the bottle.
There is no need to rush for time in the rocket competition. The judging criteria of the competition is whose rocket flies higher, and everyone has two chances. This can largely eliminate mistakes.
Of course, this does not include disposable fuel rockets like Chen Xingtian. They only have one chance.
Suddenly someone on the field exclaimed.
"Fly up!"
Sure enough, when I looked in the sky again, the first rocket that skyrocketed appeared.
The gas in the rocket continues to decrease until at some point, the rocket reaches its highest point and begins to fall.
"127 meters!"
the referee shouted.
The school has a special infrared ranging instrument that can accurately know the height of the rocket's flight, while also ensuring the fairness of the competition.
With the first count, more and more rockets flew into the sky. Such a rare sight can only appear in the Science and Technology Festival.
"87 meters!"
"135 meters!"
"164 meters!"
"27 meters!"
"Kick-kick-kick."
There was roaring laughter in the venue, it seemed that Rocket had farted.
The little boy who had only flown 27 points dejectedly ran to pick up the fallen rocket and ran back to re-inflate it.
"195 meters!"
"Wow! Bull beep!"
There were exclamations from the court. It seemed that the Rockets did not live up to the expectations of the little boy, and directly won the highest score in the game at the last opportunity.
After a while, the middle and midfield competition came to an end, with the highest score being 195 meters.
This result did not break the highest rocket record of 264 meters. Of course, this kind of record is rare and requires the right time, place and people, both of which are indispensable.
Next came the rockets of the high school group. At this stage, they were no longer just water rockets. Most of them used some simple fuels, such as methane, gunpowder and the like.
This also caused the smell of gunpowder on the field to become stronger instantly. This was not the atmosphere, but the real smell of gunpowder.
Such rockets are not as harmless to humans and animals as before. Once they hit the head, they can even break a person's cervical spine.
The teachers present dispersed some wandering students, and the remaining students who wanted to watch ran to the teaching building to avoid being hit directly on the head by a rocket parachute system failure.
These rockets only have one chance to fly. Of course, they can also be loaded if they are made of solid materials.
"3, 2, 1, fire!"
I don’t know which chuunibyou patient has such a voice. It sounds quite chuunibyou, but in terms of momentum, it overwhelms others.
Seeing this, others followed suit.
"Lingxiao, fly high!"
"Huanyu, carrying the will of my heaven, is heading towards the universe!"
…
It's getting more and more outrageous, but it feels like it's on fire!
One after another, the passionate young people were inspired by the spirit of middle school, and shouted loudly on the field. Rockets of different shapes followed and the scene was once chaotic.
At this time, Zuo Qingxuan came over: "Why don't we start yet? Do you still want to have the finale?"
"casual."
Without saying a word, she took out a laptop and started to start the preset program. There were also "click" and "click" sounds in the rocket, and there were subtle changes.
Chen Xingtian glanced at her, and then took out a simple control panel with multiple buttons and sliders. It was not as smart as computer control, but it also felt more sophisticated.
Zuo Qingxuan also glanced at the controller in his hand, and her eyelids twitched. She also made this controller by herself, and her professional appearance suddenly increased her pressure.
In order to outdo her in terms of momentum, Chen Xingtian also followed suit: "The body camera has been checked, the parachute system is normal, the propeller is normal, the gyroscope is normal, the fuel tank is normal..."
"emission!"
Zuo Qingxuan couldn't hold it any longer and issued the launch order first, and the delicate white rocket took off along with the other rockets.
Suddenly, a shocking scene appeared in the sky, with countless rockets taking off like missiles, like the end of the world.
The tails of several rockets ejected bright tail flames, throwing those rockets without tail flames directly for a long distance.
It can be said that thousands of arrows are fired together to fight for the sky, soaring up to 90,000 miles!
The entire playground became smoky and dusty everywhere, as if there had been a sandstorm.
Chen Xingtian was still calmly checking all the rocket procedures, until he was the only rocket left in the audience. The corner of his mouth twitched, and somehow it became the finale again.
"176 meters!"
"307 meters!"
"289 meters!"
…
The rockets of the high school group reached the highest point one after another. Some flew very high, and some only had the average height of a water rocket. The score difference was huge, which truly reflects the uneven quality of the production technology.
"Look at that one!"
Everyone immediately looked at Zuo Qingxuan's rocket, and some people moved in front of her because there was a real-time altitude display on her computer.
268 meters...391 meters...526 meters...
"Oh my god, what kind of magical rocket is this?"
"Is that something a high school student can build?"
"Chen Xingtian is afraid that he is going to die."
…
665 meters...781 meters...903 meters!
Finally, her rocket reached its highest point, and only a tiny rocket head could be seen in the sky.
"Oh my God!"
"Is this really the insurmountable chasm between mortals and gods?"
"This has set a new record."
Yes, this indeed broke the highest record of 723 meters three years ago, successfully raising the altitude by nearly 200 meters.
Everyone around looked at Chen Xingtian with sympathy. Why are you messing with her when you have nothing to do? When you look at the heavy rocket, it looks like a kid who can't fly high. Isn't this asking for trouble?
Zuo Qingxuan also showed a faint smile at this time. This is her true strength.
Everyone on the field had different expressions, some were gloating, some were sighing silently, and some were nervous and anxious.
Chen Xingtian didn't feel anything. He just watched the small black dot in the sky silently and opened his parachute.
"emission!"
…
In an instant, the rocket burst out into a sea of hot air waves. Everyone's hair was blowing in the wind, and the dust particles blown up made some people squint their eyes.
The grass directly below the rocket was instantly scorched, like a spring that had been preparing for a long time, waiting to explode at that moment.
"boom!"
Everyone couldn't help but closed their eyes. When they opened their eyes again, the rocket had appeared at an altitude of 100 meters and was still moving at an alarming speed.
A bright Mach ring appeared at the tail of the arrow, which should have been a sign that a fighter jet would only appear at supersonic speeds, but now it appeared at the tail, which is enough to prove the high technological content of the propeller.
Chen Xingtian did not measure his altitude in time and could only wait for a relatively long time to reach the highest point and be recorded by the referee.
However, just when the rocket was about to reach its maximum height, its tail suddenly exploded with a dark purple ring shock wave, causing the nose in front to rush into the sky at a faster speed.
There's even a double jump!
Everyone on the field was shocked to the point of numbness. Just like on the Lantern Festival stage, this is a man who will continue to create miracles.
Finally, the moment the rocket stopped, it seemed like only a moment had passed, and it seemed like an eternity.
At that moment, the infrared rangefinder in the referee's hand rang, making an emotionless mechanical sound.
"Height: 2473 meters!"
"..."
Warm applause erupted instantly on the field. They were already stunned. They were well prepared and would not be stingy with their applause.
"Zuo Qingxuan has met his nemesis in this life." Someone sighed.
"How many years has it been since the school has seen such a phenomenal student?" A teacher sighed: "This will be another myth of our Qiu Yizhong."
Chen Xingtian also looked at Zuo Qingxuan who was at a loss and smiled back with the most sincere smile.
"Sorry, you lost again."
