Gaojia Village, this village, the most prosperous intersection in the middle of Gaojia business district.

Normally it is crowded and lively, but today it is even more lively than usual.

It turns out that here today, a unique experiment is going to be held.

The son of the lampsmith in Gaojia Village, Ji Menghan, announced to the entire Gaojia Village through the 32nd Middle School that he was going to conduct a very interesting experiment here today for everyone to see.

Ji Menghan is a person that most people don't know.

But the No. 32 Middle School came forward to help him publicize, and everyone was a little curious. Generally speaking, if it is not a major and interesting event, how can it be possible to invite the school to help him publicize it?

As a result, the entire Gaojia Village was lively!

At this time, dinner had just passed, all the workers were off work, and only a few industries were still working hours.

At this time, the people of Gaojia Village were the most idle......

A large group of workers, farmers, and businessmen flocked to the crossroads of the Gaojia business district and occupied the viewing position.

Everyone immediately found out that the thirty-two, the current highest chief executive of Gaojia Village, was actually in the crowd, ready to watch the excitement. There is also a lineup of scientists represented by Song Yingxing, Bai Gongzi, Wang Zheng and others, and a large group of graduate students......

And Gao Yiye, the old village chief, Gao Laba, etc., the veteran lineup of Gaojia Village is also all there.

It's a great spectacle......

Ordinary villagers are even more curious, what is this going to play?

In the midst of all the attention, the lampsmith appeared!

The lampsmith, who is over half a hundred years old, is already a little rickety, but today he is full of red light, and he stammered with excitement as soon as he appeared: "Big ...... Everyone...... Hold on...... My son right away, right away...... Come ......."

"Hahaha! Master Ji, what did your son do?"

"Still selling Guanzi?"

The lampsmith said happily and embarrassedly, "I ...... I can't tell...... Their young stuff, I don't understand. All I know is that my son is out, hahahaha, my son is out......

He was ecstatic, and he almost couldn't get out of his breath, and Xu Dafu, the chief of the firearms bureau, rushed out of the crowd, stretched out his hands to support the lampman, patted him on the back, and helped him calm down: "Old man, you can be careful."

Both of them came out of Xi'an, and now they are one day and one place, and it can be seen from the gorgeousness of the clothes on the two of them, the lampsmith used to be ashamed of himself when he saw Xu Dafu, and he felt a little unworthy of this old man, but today, the lampsmith feels that he can stand side by side with his old partner.

"Brother Xu, let's watch my son's performance today, hahaha, his invention has been praised by Tianzun himself this time. Hahaha, although I can't read it, but it feels so powerful, hahahaha."

At this time, Xu Dafu's interest was also full.

I saw that the crowd was separated, and Ji Menghan, the son of the lampsmith, came out with a horse, and behind him, several graduate students came out, all of whom were his classmates at the same time, each holding a horse, and a total of sixteen tall horses were brought out.

Ji Menghan walked into the crowd and showed a mysterious smile: "Hello everyone, my name is Ji Menghan, and I am my father's son."

Everyone laughed, "Hahaha, if you're not your father's son, it's a big deal."

Ji Menghan was embarrassed: "I'm sorry, I was too excited and said the wrong thing. Cough...... As the son of a lampsmith, I have wanted to be a lampsmith since I was a child, and I want to make better lamps than my father."

He stretched out his hand and took out two semicircular copper lids and showed them, "Look, these are two semicircular copper lids, and if they are put together like this, they will become a hollow copper ball."

Everyone: "What is this for?"

Ji Menghan said proudly, "I want to prove to everyone today that the air is stressed."

Everyone: "Coax! It's all nonsense."

In front of everyone's eyes, Ji Menghan covered the two copper lids together, synthesized a copper ball, and then poured water into it through the small hole in the copper ball.

Soon, the copper ball was filled with water

。

Everyone couldn't understand what he was doing.

I saw that he felt a strange machine again: "This is my invention, the vacuum machine!"

He attached the machine to the copper ball and used a strange tube to connect the small hole that had just been filled with water......

Then he started the vacuum machine and began to pump water desperately outward.

The crowd of onlookers watched as the water in the copper ball was pumped out. Ji Menghan pressed the bracket on the small hole, and the bracket drove the rubber stopper to plug the hole. Only then did he remove the vacuum machine used to pump water.

Ji Menghan raised the copper ball and said with a smile, "Now, there is no water in it...... Moreover, there is no air, there is nothing in it, and Tianzun calls this kind of space a 'vacuum'."

Everyone: "Huh? I can't read it, but it looks like it's very powerful."

"The ball was filled with water, but now that the water has been drained away, it seems that there is really nothing left, not even air."

Ji Menghan stretched out his hand and gestured in mid-air, and said with a smile, "The air is pressurized. Originally, there is pressure in the air inside the ball, and there is also pressure in the air outside the ball, and the two forces cancel out, so we can easily open the two lids. But now there is no air in the ball, but there is still pressure in the air outside the ball, and it is pressing the two hemispheres together so hard that this force is much greater than the strength of us humans, so we can't open it anymore."

"I'll open it!" A strong man jumped out of the crowd, grabbed the pre-installed buckles on both sides of the copper ball with both hands, and pulled it hard, but he couldn't pull it open, and he couldn't pull it open at all.

His face turned red: "Impossible, how can my strength not even match the air?"

Ji Menghan laughed: "The fact is that it is impossible for someone to have more strength than air, not even a horse."

With a wave of his hand, the graduate students led the sixteen horses they had prepared, tied them with ropes to the two copper balls, and then divided the sixteen horses into two groups of eight horses each, pulling them from two directions and at the same time to both sides.

The audience present was all dumbfounded.

One horse can pull a thousand pounds of things, eight horses on one side is equivalent to 8,000 pounds of pulling, and sixteen horses pull to both sides at the same time, isn't that 16,000 pounds of strength?

I saw that the sixteen horses were tired and sweaty, and finally, with a bang, the copper ball was finally pulled apart.

Everyone was stunned for a short second, and then cheered: "Awesome!"

Ji Menghan laughed happily: "This is air pressure! Hahaha! I proved the pressure of the air."

It was only then that everyone suddenly reacted: "Huh? No, didn't you just say something for a long time that you want to make a better lamp than your father? What the hell is it that you're proving here that there is pressure in the air? Where is your lamp?"
