Chapter 946

Ten days later, the Datang Royal Academy, located on the other side of the Gan River in Dingzhou village, became lively.

The Academy of Notre Dame is full of dignitaries in colorful clothes today.

It's said that Li forget worry will show his majesty and officials what atmospheric pressure is today. The relatives of those officials are also itching.

Who doesn't want to see such a lively scene?

Unable to bear the bitter entreaties of the women's family members in the house, Fang Xuanling and several other national leaders took the lead and asked Li Er to play. Today, all officials are allowed to take their relatives to the academy to watch the event.

Li Er naturally nodded and agreed. He also took empress Chang sun, concubine Yang and other concubines.

Thanks to the fact that there was no shortage of land and copper money when Li forgot to worry about designing the Academy, the Academy was also built very wide, otherwise it might not be able to accommodate so many people.

"Ziyou, why are you so haggard today? Are you ready for your experiment? I'm looking forward to it!"

Li forgot to worry and stared at a pair of panda eyes. His eyes were full of red blood. With a tired wry smile on his face, he said, "uncle, fortunately, I didn't lose my life. Yesterday, my nephew led Li Ben and they finally made the devices needed for today's experiment."

He really worked hard this time.

Originally in the Tai Chi hall, I said a ten day time, thinking that there was plenty of time.

Who knows how difficult it is to really start trying to make that reciprocating piston vacuum pump.

Thanks to Li's understanding of its principle, Yan Liben is a rare "Engineering" talent in the Tang Dynasty, and with the assistance of a group of skilled and experienced old craftsmen, the vacuum pump was made on time.

Even so, Li forgetful and Yan Liben had stayed up all night and were very tired.

In this regard, Li forget worry can only sigh silently in his heart. As expected, don't pretend to be forced. Pretend to be forced by thunder!

In order to deceive the people that day, he lied a big lie, but he didn't expect that it would be difficult to round up the panic.

Fortunately, hard work is always effective. After today's experiment, we'll see who dares to question the identity of his Taoist ancestor disciples.

Li Er was very satisfied and motioned Li to forget his worries and prepare for his experiment at any time.

Li forgets to worry just a few steps, and is surrounded by dandies again.

"Ziyou, how did you get so haggard? Tut Tut, look at your dark circles. I'm afraid you haven't had a good rest for a few days?"

"Ziyou, don't break your body. It's not worth it!"

"Didn't you work so hard for my gambling appointment with Prince Joe and their bastards?"

When the dandies saw Li's appearance, they were also concerned about him, which made Li feel very useful.

Although he is unhappy, Cheng Yaojin has become a dandy and can make another profit by betting with others.

But in fact, he also knew that he owed Cheng Yaojin, Yuchi Jingde and a lot of dandies a favor.

After all, Li forgets to worry about atmospheric pressure, he knows, Su Changqing knows, but neither Cheng Yaojin nor the dandies do.

Li Qieyou can guess. He said that everyone is pressed with 200 stone air. The dandies may not believe it.

But just by relying on his trust, he dared to bet with Hou Junji, Wang ziqiao and others and make a bet, which naturally made Li forget worry feel a little sour in his nose for no reason.

"Don't worry, brother. I'm fine."

"It's all right. Wow, hahaha, today's brothers are waiting to see Ziyou how to prove the atmospheric pressure and slap those who question you! Let them know why the flowers are so red!"

Needless to say, the last sentence was learned by dandies and Li forgetful.

Li forgets sorrow and nods. Just as he is about to say a few warm words, he hears Chumo continue.

"It's a pity that Ziyou's Yanling Marquis doesn't allow it, otherwise the beautiful maidservants won by your brothers will profit you. It's a pity, Wahaha, Ziyou don't have this blessing."

"Ha ha, brother Chumo is right. Ziyou is good at everything, but you are afraid of the inside. Tut Tut, speaking of it, Ziyou have no title now, but your wife Su is the Marquis of Yanling. Ziyou still has a position in the house?"

"It's said that the Ministry of work is going to dismantle the gate of balance at Ziyou's house. Is there such a thing?"

Li, who had just been full of excitement, turned black and didn't even bother to talk to the dandies. He turned and left.

These bastards! I knew I couldn't give them a good face!

Bah, the move just now is really an illusion!

Li forgot to worry and left in a hurry, leaving behind the dandies burst into laughter

When the people were almost there, Li forgot to ask Li Er for instructions and led them to a wide lawn of the Academy.

The crowd was bustling and noisy.

Li Qieyou is very satisfied with this. After today, the madeborg hemispheric experiment in history can be removed!

Instead, it will be the hemispheric experiment of the Royal College!

Li Lianyou shamelessly YY in his heart for a while, then walked to the center of the lawn and began to talk to the people

"Your Majesty, today I want to show you what atmospheric pressure is. This is also the knowledge taught by my master, the Taoist ancestor."

"As I said in the Tai Chi hall ten days ago, each of us carries air weighing 200 stones anytime, anywhere. But why can't we feel it? It's very simple, because there are all kinds of pressures in our bodies. For example, there is blood pressure in our blood, and there is air in our stomach and lungs, which makes the pressure inside our body equal to the atmospheric pressure outside Therefore, we are not aware of the existence of atmospheric pressure. "

"But if we are not aware of it, it does not mean that atmospheric pressure does not exist. Today I will prove this to you."

Li forgot to worry and motioned Ma Zhou and Yan Liben to come forward and send the two copper hollow hemispheres.

"You guys, when these two hollow hemispheres are combined, they are a complete copper ball," Li said, indicating that Ma people have combined the two hemispheres into one.

"The two bronze hemispheres have no mechanism in the middle, so when they are combined together, they can be separated easily without force." Li forgets worry and motioned Ma Zhou to separate the copper ball again.

Li Er and other officials, as well as empress Chang sun, who were watching around, did not understand what Li forgot to worry about.

Li forgot to worry, but did not explain. He just asked Ma Zhou and Yan Liben to send the two bronze hemispheres to Li Er and other officials for inspection, saying that there was no mechanism in the two hemispheres.

Wang Ying, Hou Junji and others carefully inspected the two hemispheres several times, and finally convinced that Li forgetful's words were true.

These two hemispheres are just hollow hemispheres made of copper, with no mechanism in the middle.

"Ziyou, what the hell do you mean? Don't sell off. Get out the air pressure quickly!" Cheng Yaojin asked impatiently.

Li forgot to worry silently and turned his eyes. He didn't care about the uneducated old hooligan. He began to command Ma Zhou and Yan Liben to fill the copper ball with water, and then connect the piston vacuum pump for pumping.

He also summoned Niu Wu and other central works of the house, pulled the piston hard, and slowly pumped out the water from the copper ball.

As the water in the copper ball was slowly drawn out, the piston became more and more difficult to pull. Finally, after three or four strong men could no longer pull the piston, Li forgot to worry and asked Ma Zhou to close the valve on the copper ball.

"Next, ladies and gentlemen, is the moment to witness miracles!"

Every chapter is Tucao Shui... OK, showdown, actually I am the water god! I do not produce water, just nature's Porter! Make complaints about the water fee!
