Fina hated Zhang Zian for pretending to be mysterious. It was obvious that he was keeping it in suspense. Cats were naturally curious, and Fina couldn't stand it.
"Don't talk about this nonsense. What do you want? Are you going to tell me or not?" it said coldly, showing its claws.
Zhang Zian was a scholar facing a soldier. A wise man knew better than to fight when the odds were against him.
"It's not that I don't want to tell you. It's just that I'm not sure if we can enter the slaughterhouse safely tonight. It all depends on God," he quickly explained.
"God?" Fina looked at the night sky suspiciously. "What does that have to do with God?"
Zhang Zian raised his phone. The screen showed the local weather forecast, but it was updated during the day when there was internet. There was no internet now, so there was no way to update the real-time weather forecast.
"The weather forecast says that there might be strong convective weather tonight. The probability of precipitation is 90%. Do you know what strong convective weather is? It's extremely bad weather like thunderstorms, strong winds, hail, and so on. "
Fina's face became colder. "Are you looking down on my intelligence?"
"No …" he explained helplessly. He sat up and pointed at the forest behind him. "Do you remember the red shirt tree that was struck by lightning? When I saw that, I remembered that the air here is humid. Hot and cold air meet here. Thunderstorms are not rare. "
Fina and the elfins waited for him to continue.
"The red shirts are very tall. The taller red shirts in the forest often become the natural targets of lightning. As the saying goes, the tallest tree in the forest will be struck by lightning." He gestured around for them to see. "Look around. This is private land. There are no particularly tall ancient trees that can act as lightning rods."
The elfins all knew about this. The trees in this private land were all relatively short. They couldn't be compared to the tall red shirts in the depths of the forest.
"So if there's thunder around here, where will the lightning strike?" He didn't expect the elfins to answer this question. Instead, he pointed at the tallest building in the slaughterhouse and said, "Can you see that place clearly? There's a long lightning rod on that building. "
The slaughterhouse was brightly lit. The elfins could see that there was a tall and thin pole on top of the building pointing to the sky.
"There are no tall Red Shirts nearby to act as natural lightning rods, so the slaughterhouse has to build its own lightning rod to prevent itself from being struck by lightning."
The slaughterhouse was not very big, but it was not small either. The buildings were quite scattered, and there were lightning rods on top of a few buildings.
The elfins seemed to understand a little, but not completely. They almost broke through the last layer of window paper.
Zhang Zian took out a Swiss army knife from his pocket and began to cut the insulating rubber on both ends of the wire, exposing the copper core of the wire, which was more than ten centimeters long.
Then, he took out the box containing the drone, opened it, and assembled the drone.
"So, I'm going to use the drone to fly this wire high into the sky, at least far above the highest lightning rod in the slaughterhouse, and leave the other end of the wire on the ground, connected to the electric fence. If … I mean if, if there really is a thunderstorm tonight, the lightning will not be attracted by Red Shirt, nor will it be attracted by the lightning rod. Instead, it will follow this wire and hit the electric net. "
After he finished speaking, it took a few seconds for the elves to suddenly understand what he meant. It was simply terrifying to think about!
Richard's eyes could not see clearly, but it understood. It patted Zhang Zian's head with its wings and said, "Quack! In my opinion, with your brain, you shouldn't be a pet shop manager. You'll have a better future as a terrorist. "
Old Time Tea asked eagerly and excitedly, "Then … what will happen if the lightning hits the electric net?"
Zhang Zian shrugged. "I don't know. Just treat it as a scientific experiment."
"Have you ever considered the idea of being a slaughterhouse test subject without permission?" Richard complained.
There was a scientific story that was widely known in both China and the United States. Many Americans believed in it, and it was even included in Chinese language textbooks. It was as famous as Newton's apple and Galileo's two iron balls. This story was "Franklin's Kite."
In the 18th century, Franklin was an extremely powerful historical figure. He had a lot of famous titles, such as author, inventor, scientist, diplomat, philosopher, and enlightenment thinker. He had also made indelible outstanding contributions to mathematics and physics, especially in the field of electricity. He was one of the pioneers of electricity.
According to the legend, one day in 1752, Franklin took his son William to an open place and flew a kite in a thunderstorm. He tied a copper key to the end of the kite string. When the kite flew into the thunderstorm, a lightning flashed. He felt that his hand was numb, so he put his hand close to the copper key. As he expected, sparks burst out between his finger and the copper key. He shouted in surprise, "William! I got an electric shock! Now I can prove that lightning is electricity! "
Almost everyone knew this story. Lightning was indeed electricity, but it was doubtful whether Franklin had done this experiment himself.
The famous rumor-refuting show "MythBusters" explored this legend in the fifth episode of the fourth season. The method used was very rigorous, and the conclusion was very conclusive. If this experiment was successful, Franklin would definitely die.
In fact, a Russian scientist was killed by lightning in 1753 while trying to verify this experiment. It could be said that he had died for science.
Franklin was undoubtedly a great man, but he might not have done this experiment, at least not in the way that the legend said. Otherwise, he would probably have lost a few of his awe-inspiring titles …
In addition, his son William was not a little boy like the illustration in the Chinese textbook. If the legend was true, William was already 21 years old in 1752, a young man in his prime. William was also a politician, but he had never mentioned that he had participated in this famous experiment.
There were countless mysteries in history, and this one was not one of them. There were also many legends that people imposed on great men. Whether this experiment had happened or not, it did not diminish Franklin's greatness.
Franklin was the inventor of the modern lightning rod, but today, Zhang Zian wanted to replicate his experimental method to bypass the lightning rod in the slaughterhouse.
How high was the voltage on the high-voltage grid?
Even if it was 100,000 volts, wouldn't it be the highest?
The voltage of lightning was as high as 100 million volts!
He did not use a kite string that was soaked in the rain, but a real copper core wire.
The erratic kite was also replaced by a stable and controllable drone.
At least for this night, he was the modern version, the China version of Franklin.
The only uncertainty was whether the weather forecast was accurate.
