Chapter 1586 It's Real Enough

 Two hours later, Chi Feichi and Dr. A Li were going in and out of the house, moving things out one by one.

First, we used pieces of glass to glue together a glass box in the yard that was three meters long, two meters wide, and only about thirty centimeters high.

There was no lid on the top of the glass box. One third of it was marked out with stones and sand, and several small buildings were placed there. The remaining two thirds were filled with water dyed blue by Dr. Ali.

The three children followed into the yard and curiously watched Chi Feichi and Dr. A Li at work.

"Doctor, what are you doing?" Yuantai asked curiously.

"Environment simulation sand table." Haihara Ai said from the side, "Doctor and Brother Fei Chi probably want to use these things to simulate the environment of a patrol boat explosion, and then demonstrate the technique to you."

"The answer is correct!" Dr. Ali smiled and placed two devices under the water. He also glued two palm-sized discs on both sides of the inner wall of the glass box and pressed the remote control switch. "The thing I invented before works just right.

Use these things to simulate an environment close to the sea and the coast..."

As the remote control switch was pressed by Dr. Ali, the originally calm water surface began to ripple with waves, slapping towards the coast marked by stones and sand.

At the same time, the two disks stuck to the inside of the glass box also sucked in the wind from one side, and then blew it from the disk to the simulated sea and simulated coast.

Conan laughed inwardly.

With Chi Feichi's reminder first, he ruled it out. After thinking about it for a long time, he probably guessed that it was the key to this technique.

The doctor and Chi Feichi are really serious about the restoration...

Dr. A Li also used equipment to detect the wind direction and the strength and direction of the waves, and tried his best to restore the situation at the seaside. He turned to Chi Feichi and said, "Feichi, I've finished it here! It's the data we agreed on before!"

Chi Feichi stayed on the coast, placing electronic equipment on several small buildings behind the coast, powering on, and debugging, "I'm almost done here."

Bumei walked to Chi Feichi and bent down to look curiously at the things Chi Feichi put on the simulated small building. "Brother Chi, what are the things here?"

Okiya Subaru bent down and leaned closer, "If I guessed correctly, it should be electromagnetic equipment, right?"

"This is what the doctor just made temporarily." Chi Feichi adjusted the equipment and raised his head and said, "Doctor, the ship can be released."

The three children could only resist the urge to ask questions and looked towards Dr. A Li.

Dr. Ali picked up a small iron boat, turned on the switch under the boat, and said with a smile, "This boat is equipped with small power equipment, which can simulate the power of a yacht equipped with an engine. The bottom is also weighted, even at sea.

, and it can drive steadily!”

"I'll use this to simulate rifle bullets."

Chi Feichi took out a small iron particle that was twice the size of a grain of rice and looked at Dr. A Li.

Dr. Ali put the iron boat into the water, stepped back and said, "Okay, everyone, stay away from here and go behind Fei Chi."

After the iron boat entered the water, it drove towards the opposite direction in the wind and waves, with two intertwined white lines trailing behind the boat. Under the sunlight, it really looked like a patrol boat riding the wind and waves on the sea.

"so beautiful!"

"The boat goes so fast!"

"Just like a real ship sailing on the ocean!"

The three children exclaimed in surprise and followed Haibara Ai, Conan, and Okiya Subaru behind Chi Feichi. Their eyes still refused to move away from the ship.

"If it were an ordinary rifle shot, it would be impossible to hit the ship at this position..."

Chi Feichi said as he put small iron particles into the end of a tubular device.

"Boom!"

The front end of the tubular device ejects small iron particles. Although the initial speed and force seem to be very strong and almost invisible, under the simulated sea breeze, the speed and force are still rapidly weakened. When it can be captured by the naked eye,

With a pop, it sank into the sand that simulated the intersection of the coast and the sea.

Mitsuhiko nodded, "The wind is indeed too strong..."

"The distance is also very far."

Ayumi looked at the boats moving in the water.

Since the sand table was made relatively realistic, when they looked at it from here, it seemed as if they had just turned into giants and were looking at the ships on the sea from across the coast.

Compared with the iron boat, the small iron particles flying past are like mosquitoes swooping at the elephant. Not to mention hurting the elephant, the strong wind flying towards the elephant can stop the mosquitoes from flying.

"But if electromagnetic push is added..."

Chi Feichi placed the tubular device behind another cube device, made sure that the tube opening was aligned with the hole in the middle of the cube device, turned on the switch that connected the cube device, took another small iron particle, and placed it at the end of the tubular device.

end.

This time, a group of people didn't even see the shadow of the small iron particles. The next second after Chi Feichi put the small iron particles into the end of the tubular device, there was a loud bang, and the iron boat two meters away was already in flames.

shrouded.

"Snapped!"

The upper half of the iron boat fell to the water in the distance, with wisps of black smoke rising from it.

While the three children were stunned, Dr. Ali extinguished the fire on the iron boat. Looking at the iron boat that was cruelly broken into two pieces, he scratched his head and said, "It seems that just adding weight to the bottom of the boat is not enough. The hull also needs to be repaired."

Reinforce it, otherwise the ship will be seriously damaged like it is now. If it is a real patrol boat, at most it will catch fire due to the explosion, damage the kinetic energy and deviate from the course..."

Conan: "..."

There is no need to be so serious, this is real enough.

And rather than whether the boat has restored the strength of the patrol boat, the children are now more surprised by how that small iron particle can do this, right?

"W-why is this?" Mitsuhiko looked at the cube device in surprise, "Can it become so powerful just by adding this device?"

"That's right," Dr. Ali came over and raised his right index finger with a smile, "Under the impetus of electromagnetism, the speed of small iron particles flying out will be beyond imagination, and the force hitting the iron boat will be many, many times greater, even

It had already caught fire due to friction in the air, but because the speed was too fast, no one could see it..."

Chi Fei belatedly saw Yuantai reaching out to imitate shaking on the coast, and said calmly, "If you had just put your hands into the trajectory of the iron particles, the iron particles could even penetrate your palms."

Yuanta shivered and quickly retracted his hand.

Brother Chi's voice is cold and scary...

"So this experiment is very dangerous!" Dr. Ali added sternly, and soon laughed again, "You will learn the principles of this experiment in a few years, and the teacher should also use magnets and small iron balls to lead you to do similar experiments.

Experiment, be careful not to hurt your companions when the time comes."

Mitsuhiko thought about the idea of ​​"explosion" being taught in schools, and his face turned pale, "Do elementary schools also have such dangerous experiments?"

"If it were just an ordinary magnet, the speed and force of the iron ball popping out would be much smaller, and it would not be so dangerous," Haiyuan Ai said with a smile on his face, "The premise is, don't lie down and look at the opposite side, otherwise your eyes will

Once such a fragile part is hit by an iron ball, it may be injured and blinded. If it is hit on the body, it will be much better, it will probably just be more painful."

Three children: “…”

It still feels very dangerous.

"Okay, okay, don't worry." Conan was worried that the three children would have psychological shadows on physics and other courses in the future. "As long as you listen to the teacher and don't make dangerous moves, you will be fine."

Genta glanced at Conan, "Conan, don't make it sound like you've done this kind of classroom experiment."

Conan: "..."

He actually did it.

"But why does Brother Chi say that the doctor can do it, but Officer Sato and Uncle Maori can't?" Ayumi asked in confusion, "Don't Officer Sato and Uncle Maori know this?"

"They know this, but they may not be able to think of it, and they may not be able to do it," Haibara Ai explained. "If they want to accurately hit the moving patrol boat and detonate it, they must know the position of the electromagnetic equipment and the angle at which the bullet is fired.

To accurately calculate data such as electromagnetic driving force, wind speed, wind direction, humidity and other factors must also be included in the calculation. On a real coast, the airflow will be more complicated than this sandbox. Even if Uncle Mori and Officer Sato thought of it, they would not be able to calculate it accurately.

It's difficult to calculate. If a doctor needs to study those inventions, he must master the relevant knowledge, and his ability to calculate data in this area will be better than them, so it was Brother Chi who said that."

"Yes, the principle is very simple, but the actual application will be very complicated and requires many tests and calculations." Dr. Ali saw the three children looking at him with bright eyes, raised his hand to touch the back of his head, and said with a smile, "But today

Data calculations and equipment adjustments are all done without delay. During this time, I was responsible for making the ships needed for the simulation and formulating a plan for simulating waves and sea winds."

Okiya Subaru stood aside with his eyes narrowed, smiling and saying nothing, feeling a little emotional in his heart.

In order to demonstrate a technique to children, I only need to calculate data and make a mechanical model. The conditions of these children are really good.

Well, Shirley looks very lively and active today, completely different from the cold-faced look she had in the past two days.

"Doctor..." Mitsuhiko looked up at Dr. Ari, his eyes shining with anticipation, "Can you also let us try this experiment? Because it's really amazing!"

"this……"

"Doctor, please!"

Dr. Ali couldn't stand the entanglement of the three children and looked at Chi Feichi in embarrassment.

Chi Feichi looked coldly, "This is not a toy."

"ah……"

The three children suddenly felt disappointed, but they did not dare to pester them.

"But we can let them try similar experiments using magnets and iron beads. As long as they don't mess around, they should be fine." Chi Feichi looked at the setting sun, "Doctor, there aren't enough ingredients for tonight. You can help them do it."

Experiment, I'll buy some."

"You have been busy for so long recently and rarely take a break, so just relax." Dr. Ali lowered his head and took out his wallet from his pocket. "It is better that you take the children to do experiments, and I will go buy groceries..."

Chi Feichi turned around and walked out of the gate.

Doing experiments with a naughty child is much more tiring than going shopping for groceries.

He chose to buy groceries.
