"Is it necessary to hide so far?" Xu Da turned his head and laughed at everyone.

After a few moments, he felt a tremendous force coming from inside the pot, and kept pushing the lid up to compete with his strength. Within a few breaths, he showed signs of being unstoppable.

With my Xu Da's strength, I can't hold down the lid of the pot? I'm a martial arts master!

Xu Da refused to admit defeat and continued to press down hard.

In the end, he actually squatted down, sank into the dantian, and used the true qi.

"Let go, danger!" Seeing this, Qin Yu hurriedly shouted.

As soon as the words fell, with a 'Peng' sound, the pot exploded, and the iron lid was blown apart.

The boiling water suddenly splashed everywhere, and the more destructive water vapor rushed towards Xu Da. Xu Da hurriedly dodged sideways with an arrow step, but he still didn't dodge, his face was burned by the steam, and he was red.

Fortunately, he has martial arts and is agile, so he didn't cause too serious burns.

And when Qin Yu and the students saw the hot water falling, they also dodged in an instant.

Just like the teachers and students of the martial arts school, he and this group of students have also practiced martial arts.

"How are you, are your injuries serious?" Xu Miaojin hurriedly ran over and asked with concern. Because I can't recognize him, I don't call you dad but you, but you can see from his eyes that it's worried from the heart.

Could it be that this little girl worships Uncle Biao? Qin Yu was surprised when he saw this. Well, well, adolescent girls have strange ideas, and you have to find a time to talk to her so as not to go astray.

"It doesn't matter, it doesn't matter, hiss......" Xu Da said, "Fortunately, I hid quickly just now." ”

"It's all told you to stop in moderation, you don't listen, is the power of steam something that human power can contend with?" Qin Yu said, "The steam can even push the train, how can you be a mortal in the flesh to fight against it?" ”

"Aren't you stupid?"

"I'm sorry for my previous life, I just didn't admit defeat just now." Xu Da said embarrassedly.

"I think you better find the Lingshu girl to get you some medicine, and you won't be able to find a wife even more if you are disfigured." Qin Yu said, "But before leaving, you first tell me whether the pressure of the steam is great." It was also seen that his injuries were not too serious, and he was hiding a little fast just now.

"It's big, it's too big, it's terrifying!" Xu Da said, "I have tried all my strength just now and failed to hold it, and I feel that all my strength is not even one ten-thousandth of the steam." ”

"It's like a martial arts master, as soon as I exert my strength, the opponent's true qi will flood towards me, and it will defeat me in an instant."

"Who told you not to listen to the command?" Qin Yu sighed, "What about the martial arts master, can the martial arts master be compared to steam?" As long as the temperature of the ignition source is high enough, the power of the vapor can theoretically reach infinity. ”

"Infinite!?" The crowd was stunned.

"I'd better go find the little girl to help deal with it first." Xu Da felt a hot pain on his face, and turned around to find the Lingshu after speaking.

"I'll check it out too." Xu Miaojin left after him.

It seems that I really want to talk to her, Qin Yu thought to himself.

"I didn't expect that I, Xu Da, have rarely been injured in battles all my life, Hu Yuanqi's man Wang Baobao can't hurt me, and today I was actually injured by steam." After walking out of the gate of Lujiacun Primary School, Xu Da sighed with emotion.

"This involves the physics of immortals, is it something that your flesh and blood can contend with? Mr. said that as long as you learn physics well, you can destroy a city with one bomb, and tens of thousands of people in the city will be wiped out in an instant. Xu Miaojin looked at the sadness on his father's face, and complained about his father, "You should really obey Mr. just now, and let go if you can't hold it down, this time you will suffer a big loss, right?" ”

"I just don't think the steam can be that powerful." Xu Da said embarrassedly.

"What do you think?" Xu Miaojin said, "Don't think about it, you have to think about it." ”

"In physics, we have to listen to Mr. for everything. Even if you don't think something is possible, you can't make your own decisions. ”

"My daughter has a point." Xu Da sighed, "The power of steam is terrifying, completely beyond the thinking of normal people, it can be seen that it is really possible for Mr. Qin to destroy a city with one bomb and make tens of thousands of people disappear in an instant." ”

"It turns out that you didn't believe Mr. all along." Xu Miaojin sighed.

"How can you make me a normal person believe this kind of thing?" Xu Dadao, "Destroying a city with a single bomb and destroying tens of thousands of people in an instant is not comparable to the power of the gods?" ”

"Believe it or not, I believe Mr. unconditionally." Xu Miaojin said.

"But what kind of bullet he said is too exaggerated!" Xu Dadao.

"My daughter doesn't think it's an exaggeration." Xu Miaojin said, "Even if Mr. says that he can do it in the sky, my daughter is convinced." Maybe we can do it, because my husband told us about airplanes. ”

……

on the playground.

"Now you've seen it, right?" Qin Yu said, "The power of the steam is beyond your imagination. ”

"We can't assume that the kinetic energy of the steam is very small just because we see that the steam can only push the lid. In science, taking things for granted will make you miss out on a lot of things. ”

"For example, when we see an apple on the ground, we take it for granted that we can't find gravity."

"Sir is right, in physics, of course, it is not true." Zhu Fan said.

"So you have to test it yourself to see the truth of the matter."

"It's still the sentence that Mr. often puts on his lips, science must not be false. Doing experiments to obtain data is the only way to seek truth from facts. ”

The crowd said.

Through the experimental demonstration just now, this group of students realized how wrong their previous ideas were.

The illusion that the steam pressure is very small also misled the ancient Chinese sages for thousands of years, so that they did not invent the steam engine.

Sure enough, it's a blind eye.

The pressure of the steam just now was so terrifying that it went straight to the pan in less than a minute, and the lid of the tin pot was blown up.

"Vapor has such a huge power, and if it can be used wisely, it can do a lot of things......

The thinking of this group of students suddenly became active.

"If you want to build a steam turbine, you have to know about it." At this time, Qin Yu said.

"In the West in the eighteenth century, the advent of the steam engine directly triggered the first industrial revolution. The so-called industrial revolution is a earth-shaking change in industrial manufacturing, replacing traditional manual manufacturing with machine manufacturing. ”

"That is to say, as long as the steam engine can be built, it can be immediately applied to all walks of life in society, completely changing the social mode of production, replacing manual labor with machines, and greatly improving social productivity."
