Chapter 347 Mother’s Grace to the World

"Any knowledge is useful. It depends on how the person who uses it uses it and where it is used. You are the princes. You must know more to convince the world. Go in first and we will conduct the next experiment. I will put the glazed lens On the tool rack in the classroom, you can use it by yourself in the future, but you must be accompanied by a palace official to avoid danger."

After watching the first experiment, everyone became more and more curious about the next one, especially the princes. Even though they were usually very stable, after all, even the eldest prince was only ten years old. How could he not have a childlike innocence?

In addition, both the prince's office and the study room were extremely boring places. They finally saw something interesting today, and they wished that the class could last longer.

"For the second experiment, I want to talk about the composition of air." She looked at everyone with a smile, "Everyone knows that the nose is used to inhale and then exhale, but have you ever thought about what we inhale? Is the breath different from the exhaled breath?"

As soon as these words came out, everyone became confused again. The eldest prince, prince, third prince, fourth prince, fifth prince and sixth prince, who were sitting next to each other, all looked at each other subconsciously, and then quickly looked away.

Concubine Shu and Concubine Zhen were very amused, and then they also looked at each other.

After giving gifts to the queen last time, the maid reported to them that the other party also gave gifts to the queen. At that time, she sighed that this was the first time that she had touched each other's true thoughts after so many years in the harem. Today, when they looked at each other and smiled, they felt even more excited. I must be guessing in my mind.

Originally, I thought I was the only one who didn't worry about it, but now that I know there is another person walking the same path as me, Concubine Shu and Concubine Zhen feel more at ease.

Coupled with the fact that the queen is in charge, maybe it can really lead to the ending they expected!

"If you have read a lot of travel notes, you should know that some people will feel difficulty breathing when climbing some high mountains, and people who have lived in high mountains for a long time will feel drowsy or even sleep to death if they go down to the plains. In the past, the reason for this was that different tissue contents in the air were different, and each other's bodies could not adapt to each other's living environment."

Zhenbi said: "Isn't it just like people can't breathe in the water and fish can't live on the shore?"

Song Xia nodded in praise: "Zhenbi is very smart and can think of this. There are some principles involved, but most of them are that humans breathe with their lungs, while fish breathe with their gills. Lungs and gills are two completely different things. organs, so the principles of breathing are different. I will talk about these in future classes. If Zhenbi is interested, you can come to the class from time to time. Today we will do a small experiment to prove that there are different types of air in the air, and their effects are also different. .”

Zhenbi was a little happy. Can she come to attend classes in the future?

To be honest, the Queen's lectures are really interesting. You can learn knowledge that you have never heard of before. The harem is so boring and there is nothing but intrigues. Coming here to listen to the lectures is just a good way to pass the time.

Similarly, Concubine Shu is ready to make a move. If Concubine Zhen can come, then she can come too, right?

What Concubine Zhuang, Concubine Xian and Concubine Li wanted was that they must come and watch the Queen in class, so as not to teach their prince a bad lesson. They also wanted to see how much knowledge the Queen could teach, and they must catch the Queen's mistakes. .

A few of them didn't know that what they were thinking was exactly what Song Xia wanted, so it would be better if they all came to attend the class. Education is the most direct way to change a person's thinking.

"These tools and materials are what we will use in today's experiment. After this experiment, I will also order people to put them on the tool rack. Anyone who is interested can operate them by themselves."

What Song Xia wanted to conduct was a small experiment in the modern society where she lived. Junior high school students were required to learn the small experiment of using potassium permanganate or hydrogen peroxide solution to reduce oxygen. The source of the medicine was difficult to explain, so she said it came from some Found by chance in the hands of a Taoist priest.

Anyway, since Your Majesty became a believer, Taoism in Xuanguo has blossomed everywhere. Some Taoist priests who were previously anonymous have appeared one after another, bringing everyone a lot of novel knowledge and things. It is not unusual for her to bring it out now.

She hadn't done this experiment for a long time. If she hadn't reviewed the principles last night, she would have been really worried about failing.

She used the drainage method to collect oxygen, so everyone saw that the glass bottle that had just been filled with a bottle of water slowly floated in the sink and gradually turned into an empty bottle.

Song Xia closed the bottle and looked at everyone with a smile: "Those who know a little about life should have heard that you can make fire in some places, but not in other places, especially in caves, or in cellars and secret rooms dug by the people themselves. , I often hear that people cannot come out after entering. I think it is caused by the different air content inside. Often, fire cannot be ignited in these places." She paused and continued to explain: "So I would venture to guess. , the air components required for making fire and human breathing have certain similarities, and the air we just experimented with is a high-concentration component, which I call oxygen."

"Oxygen? So it's difficult to breathe because there is less oxygen in the mountains?"

"That's right, even if you light a fire in the mountains, the intensity of the fire will be smaller than that in the plains, because the oxygen content in the plains is higher. If there is higher purity oxygen, guess what will happen?"

The six princes shook their heads in confusion, they really couldn't think of anything.

Song Xia chuckled: "Then let's do an experiment. If there is no oxygen, the fire will go out. So if there is enough oxygen, will it spontaneously ignite without wind?"

How can this be?

The Tutor denied it at first, and then he thought about it. Doesn't the Huozhezi always burn by blowing on it? Is it because of the wind? It shouldn't necessarily be the case. It may have something to do with the experiment the Queen just did.

"Let's try that branch. Now this branch has been ignited and blown out by me. Under normal circumstances, it will not burn again, but if you look carefully, what will happen if we put it in the oxygen bottle?"

Everyone held their breath and stared at the glass bottle. They saw that after putting a branch with only a little spark in it, it burned almost instantly.

"hiss……"

"He actually started a fire by himself."

"This is amazing."

And that's not the only thing that's magical. Song Xia took out a branch, heated a piece of iron wire red, and put it into the glass bottle. The wire also started to catch fire. This was iron wire, it was only red-hot just now!

Song Xia continued to put in: "Burning will consume oxygen, so if I put in wires and branches at this time, they will no longer be able to react."

Everyone wanted to speak, but they didn't know what to ask. They just had burning eyes and a sense of urgency to gain other knowledge.

Song Xia was satisfied: "That's it for today's class. I will give more detailed and in-depth answers to these two small experiments in the future."

It’s like scratching the itch in everyone’s heart. Is this the end? Will the Queen say nothing more?

Song Xia thought to herself, what's the point of saying it all at once? I have to arouse your curiosity. Take your time, there is still time.
