After the classroom was cleaned up again and the windows were closed, Dang Aiguo ordered the students to return to their seats and sit down, then walked back to the front of the podium and said directly to the students below: "You have anything you want to ask, you can ask now."

This time, almost all of the students below raised their hands. Sure enough, the behavior of these guys is very consistent with the Chinese people's pragmatic concept: if you don't give us some "dry goods", you are a real god standing in front of everyone, and we Chinese people won't miss you.

"Principal, is this the thunder in the palm of the immortal family?"

Gan Ning, who raised his hand to the highest point and had already stood up, received the permission from the Party Patriotic question. But when he spoke, the Party Patriotic knew that it was a big mistake to ask him, and even his underwear was wrong. This kid usually hides deeply, and when he was blown up by this flour bomb, he exploded feudal superstitious ideas, which shows that the Party Patriotic scientific ideas have not yet been truly deeply rooted in people's hearts.

However, it is no wonder that Gan Ning was from Linjiang, Ba County, Bashu, and this Ba land is connected to Shu. During the reign of Emperor Shu, Zhang Daoling entered Heming Mountain in Shu, created Fu Shu books, and created the Five Doks of Rice Dao. Later, it was spread by Zhang Heng, son of Zhang Daoling (Zhang Heng, who did not create the seismic sphere and the armillary sphere), and it was popular in Bashu and Hanzhong. Now the leader of the Five Doks of Rice Dao is Zhang Lu, the grandson of Zhang Daoling. Because there are many people around him who believe in Taoism, it is natural that Gan Ning heard some Taoist mythological stories when he was young.

With current scientific knowledge, there are many things in the world that cannot be explained accurately. Whether it is explained by science or mystery, it is almost the same in the eyes of most people. If you only rely on "belief" to make judgments, you are actually not who says it is true, but who says it sounds more like it is true.

The preconceived harm lies in this. What theory should be accepted first? The previous theory should be washed away by using the latter theory, which is not as easy as a computer.

Dang Maiguo glanced at the students below. Seeing Gan Ning's question seem to be quite representative, he couldn't help but look embarrassed. But this matter was too urgent, and it was useless to lose his temper at the students who asked the question, so he could only patiently explain: "Didn't I say that, that's just flour. Under certain conditions, if you ignite it, you will explode, not a thunder in your palm."

"Why isn't it a loud thunder in the palm of your hand?"

Although the Party’s patriotism explained, Gan Ning did not give up. He asked again, and this made the Party’s patriotism choked. According to Gan Ning’s logic, as long as the condition of “thunder can be emitted from his hands” is met, wouldn’t it be called “Palm Thunder”? This has nothing to do with whether it was created by the immortals.

"If you only look at the final effect, it is the same as the so-called 'Palm Thunder'. It's just that it is not created with any magic power, and there is no magic power in this world. This is created by humans using their own minds and using scientific knowledge and tools."

Although he knew that saying this might be unfavorable to his future education plan, the Party Patriotic still chose to tell the truth to Gan Ning. It doesn't matter if the knowledge he taught was wrong, because he had already told the students that scientific knowledge that is proven to be correct now may not be correct. But he cannot lie to students easily, because lies will always be exposed one day.

"Scientific Knowledge? Principal, as long as I continue to study, can I use scientific knowledge and tools like the principal to create palm thunder and something more powerful than palm thunder?"

Gan Ning is of course familiar with the words "science" and "tools" that the Party and patriotism often talk about, and asked with great excitement. Well, it seems that the Party and patriotism education are still effective. But what is more effective is China's pragmatic way of thinking. Thanks to it, more than half of the students are now like Gan Ning, and are looking forward to the Party's patriotism answers.

"Of course, depending on the knowledge you have learned, the various tools you can make, including weapons, are even better. However, the experiment of sifting flour just now is very simple, but it is very dangerous. If you want to do it yourself, you can't use so much flour like me, and you have to redesign a safe experimental method for me. Without my approval, you are not allowed to conduct experiments without authorization."

The Party and Patriotic continued to follow Gan Ning's words and successfully improved the enthusiasm of these ancient students to learn. However, he was afraid that these students would conduct experiments in a hurry, but they would blow themselves to pieces before they even left the army. That really corresponded to the poem "Die before they succeeded, and the heroes would burst into tears."

The students below did not doubt the power of this flour explosion experiment. From the huge sound and the hot wind blowing from the explosion, they could already infer that this power was not something that human bodies could bear. As for why the Party’s patriotism is fine? That is the “future human god”. Didn’t they see that his clothes were spotless?

The students here have more or less inquired about the legends of the Party’s patriotism, and later they saw that he was no different from ordinary people. Perhaps they began to doubt the so-called “invulnerable” and “holding lightning” from the bottom of their hearts. But after this experiment, most people looked at him unconsciously brought some awe.

This is also one of the reasons why the Party Patriotic country demonstrated the dust explosion experiment to them on the second day of the school year, before teaching chemistry courses in detail. Listening to the ears is false, and seeing is true. Although the Party Patriotic country does not need to pretend to be a ghost, at least it has to make these students feel more serious and awe of science. In this way, when learning the basic knowledge that is more abstract and boring in the future, most people can also use more snacks. After all, not all knowledge can be arranged to be explained by an experiment that will be attracted at first glance.

After the Party and patriotism seriously warned these students, many people lowered their heads and thought about something, and didn't know if they were thinking about doing experiments secretly. Although this shouldn't be the case, if someone really had such a bold person, the Party and patriotism could not be watched, and they just made them ask for more blessings.

At this time, he saw many scholars raising their hands again, and curiously called Jia Xu, who was rarely raised to ask questions. Jia Xu, who was over 40 years old, bowed his hand, and his eyes were rarely shining. He raised several related questions in one breath.

"Master, based on the principle of this flour explosion, can we create a powerful weapon? In addition to scaring war horses, shaking and killing enemy soldiers, and destroying morale, this weapon has other functions? In addition to flour, there are other substances that can explode?"

Hehe... I asked, but finally asked. The Party Patriotic smiled in my heart, and the strange smile that was unconsciously revealed on my face was immediately captured by the extremely smart Jia Xu. But no matter how Jia Xu calculated the plan, he could not guess why the Party Patriotic smiled like this at this time. Through the expression that the Party Patriotic inadvertently revealed, he felt that he might have jumped into the pit dug by the Party Patriotic. But he couldn't figure out where the Party Patriotic digged and what the digged pit was.

In fact, the truth is not that complicated, because Jia Xu's name as a "poisonous soldier" is very impressive to the Party and Patriotic. Therefore, since he came to Luoyang, he has always been very low-key, but it is quite conspicuous in the eyes of his Party and Patriotic Special attention. For such a "problem student" who never raises his hand to ask questions and does not like to show himself, the Party and Patriotic Special Special Relationship will naturally pay extra attention to it.

Now Jia Xu is also interested in what he teaches. Even after his self-introduction yesterday, he raised his hand to ask questions for the first time, which made the Party’s patriotism feel like “win” in his heart. If Jia Xu knew that it was actually just because of this nonsensical reason, the Party’s patriotism would have cost him a lot of brain cells, and he would definitely feel frustrated in his heart.

"Materials that can meet the rapid combustion and rapid expansion of volume can explode. Generally speaking, powdery substances have a larger contact surface with air and burn faster. Therefore, places that can produce a large amount of combustible powder need to be strictly prohibited.

Wen He could see at a glance that he could use this explosion principle to create weapons, and his eyes were really sharp. The explosion was mainly because a certain substance expanded rapidly after burning rapidly. As long as the substance that expanded larger after burning could be found, the power of the weapon was naturally greater.

However, it can not only rely on the sound to scare people. In the "Han Shu·Five Elements Record", two iron furnace explosions were recorded, directly blowing out several feet of deep pits on the ground, and the entire iron furnace was also blown up. This can also be done when making weapons, using the power of the explosion to push the broken shell to hurt people. Moreover, the explosion is powerful and can also be used in open mountains and quarrying, etc., and it is not necessarily used in war."

Dang Maiguo has done some homework in the explosion, and his explanation made Jia Xu look thoughtful. However, the explosion of the iron furnace recorded in the Han Book was not found by him when he checked the information, but when he went to the iron smelting workshop to explain to the craftsmen the method of using coal to make coke and then using coke to smelting iron, the redox reaction during iron smelting, the relationship between carbon content and steel, and various knowledge about alloys, he heard from the officials supervising the iron smelting workshop.

However, the Party Patriotic only knows a concept of "coking" and does not know how to operate it in detail, and it is even more impossible to perfectly solve the problem of blast furnace explosion. Therefore, he could only explain the knowledge about air pressure and the knowledge about explosion, and then ask the craftsmen to slowly infer the cause of blast furnace explosion from the perspective of air pressure and combustible gases in the furnace to slowly infer the cause of blast furnace explosion and find solutions.
