Li Lin is now like a mouse that sees a cat, hiding in the corner and shivering, Gao Meimei said that he didn't even dare to come out of the atmosphere, Lu Zifei and Master Li kept teasing Li Lin with a smile, the so-called one thing descends one thing, and the happy enemy is like this, right?

Gao Meili devoured the food on the table, patted her stomach, only to find out that this was someone else's home, and said embarrassedly: "You people are not very good, but the dishes are good, it's a pity not to open a restaurant." ”

Lu Zifei was afraid that Gao Meili would be embarrassed, so he didn't break it, and said: "The girl is full, Li Lin, I helped you find it, if there is anything, you can talk to him slowly, let's go first." ”

Li Lin grabbed Lu Zifei's arm and said, "Xiucai, do you really want to see death and not save it?" Okay, isn't it a good brother? ”

Lu Zifei said: "It's good for you to enjoy this kind of good thing alone, and I won't share your joy with good brothers." ”

Master Li said, "Will your brother be killed?" Miss Gao's skills are really terrifying, and she can fight with the little wolf for so long. ”

Lu Zifei said: "You don't see that they are Wang Ba looking at mung beans, looking at the right eye, there will be nothing wrong, Miss Gao is also a proud nobleman, she won't know the severity, what are you busy with today." ”

Master Li said: "I'm going to my godfather and godmother again, whether you go or not, I'll send them some vegetables when the weather is dry." ”

Lu Zifei said: "I won't go, Lao Yao asked me to come over, I'll go see if there's something wrong with him." ”

"Boss, I'll burn out the cup you want, do you think this is what you want?" Old Yao Xianbao took out a glass and shook it in front of Lu Zifei's eyes.

Lu Zifei took this impure glass in his hand and sighed in his heart; It really burned out, although it is not as pure as the later generations, this is a matter of craftsmanship, and it is only a matter of time before it is better, he said to Lao Yao: "Reward the glass workshop with a thousand yuan, just go directly to the account room to receive it, and tell the craftsman that there are better and more discoveries, and what awaits them is more money." ”

Lao Yao Le thanked Lu Zifei and said, "Family master, there is really a small discovery here, which was accidentally made by the craftsman. A small lens reflects Lu Zifei's face in this life, with a delicate face, thick black eyebrows, and a straight nose bridge, he is really handsome, just a little immature, a standard beautiful man.

Lu Zifei said: "Can you get a big piece?" This one is too small. ”

Lao Yao said: "Yes, I'll send it to you when it's done, it won't take much time." ”

Lu Zifei still has two classes to attend today, thinking of today's glass and mirrors, he feels that it is right to let this group of children get in touch with science first, and teach them basic natural sciences without being too ignorant.

Walking into the classroom, the students stood up and said "Hello sir", Lu Zifei nodded and said, "Sit down, I won't have math class today, put away the textbooks, and show you something interesting today." "First of all, cultivate their interest, and when they are interested, they will naturally delve into it, and let them discover the magic of this world on their own.

A group of people came to the door of the kitchen, Lu Zifei went in and poured two catties of vinegar into the pot first, and then poured a catty of oil on top of the vinegar, the whole looked full of oil, and came out with the pot and said to the curious students: "I can take out these copper coins in the hot oil pot today, believe it or not." ”

Shen Kuo walked to the pot and dipped it with his hand, put it in his mouth and tasted it, it was indeed oil, and he said to Lu Zifei: "Sir, this is impossible, unless you don't want your hands anymore." ”

Lu Zifei said: "The teacher took it out today, you can't be naughty in the future, and you are not allowed to make trouble in class, how about it." ”

In the process of heating the oil pot, Wan Ming, Wang Weiwei, and Liu Yong were all alarmed, and Wang Weiwei said: "Wan Lao, can you take out those copper coins from the hot pot?" ”

Wan Ming said: "Take out my hands from the hot oil pot, some secret methods on the rivers and lakes should be fine, but they are all lies, why is this kid crazy today?" He dared to do such a dangerous thing. ”

The rising heat showed how hot the oil in the pot was, everyone's hearts were hanging, and the two panda-eyed Li Lin stood in front of the oil pot and said: "Xiucai, you are making such a fuss, it is too painful to seek death, and in the end it may still be half-dead, or you choose a simple one, I feel that the dagger on the little wolf is quite sharp, and it is fast and convenient and does not need to be punished." ”

Lu Zifei said: "Hurry up, the world is so beautiful, I haven't lived enough?" If you want to die, you will die by yourself, isn't it just to take a simple copper coin, look at your cowardice, and you will definitely have tracheitis in the future. ”

Liu Yong said: "Old immortal, your burn ointment is ready, no matter how bad it is, you can save an arm." ”

Wang Weiwei said lightly: "What are you worried about, have you seen him do something that he is not sure of, in some aspects of medical skills, he can be my teacher, he will not know what he is doing, let alone in front of students." ”

Liu Yong saw that Wan Ming and Wang Weiwei were confident, so he didn't say anything more, Li Lin also stepped aside, Lu Zifei rolled up his sleeves, his eyes stared at the bubbling oil pot, he knew that the boiling point of vinegar was relatively low, and the seemingly boiling oil pot was actually about forty degrees, and before the vinegar evaporated, the hand he stretched out was 100% safe.

After the oil pot was completely boiling, Lu Zifei calmly stretched out his hand to prepare for action, the female students and the younger children closed their eyes in fear, one, two, picked out four, and left one in the pot, picked up Shen Kuo, gave him an encouraging look, Shen Kuo closed his eyes and touched the last copper coin, and said in surprise: "Sir, why is the temperature below not so high?" Looks scary. ”

Before Lu Zifei could answer, Li Lin also wanted to reach out and try it, but Lu Zifei knocked his hand off and said, "You don't want to die, if you go down now, it will really become fried pig's trotters." Not only Li Lin, but many students were eager to try, and Wu Pan took out all the pocket money he had saved and prepared to throw it in.

In order to put an end to their thoughts, Lu Zifei asked the cook to take a chicken leg and put it in the pot, and the chicken leg became golden in a blink of an eye, at this time they knew that the temperature in the oil pot was not fake, it could really burn people, and the chicken leg would not deceive people.

Wang Weiwei said: "Hanzhang, what is the reason, why are you and Shen Kuo's hands okay." ”

Wan Ming said: "There is definitely something else in the pot, this thing can allow him to easily take out the copper coin in front, but there is a time limit, when the time is up, the thing is gone, and the rest of the pot is all oil, then you see that he will not let the little monkey reach out to try, I think the truth is not far from what I guessed." ”

Lu Zifei said: "Grandpa Wan is amazing, almost as you said, that thing is vinegar, vinegar can reach forty degrees of boiling, and oil needs hundreds of degrees, you saw that the boiling is only vinegar, so the oil pot is not as hot as imagined, and then the vinegar is burned, just like Grandpa Wan said, it is all oil, and God's hand does not dare to stretch it out." ”

After solving the mystery, Lu Zifei took the students back to the classroom again, and the students did not come out in the shock just now, so Lu Zifei said to them: "I will tell you some things like this later, and you think about the truth yourself." ”

Wu Pan said: "Sir, you can talk about a few more, this is really more interesting than math class." ”

Looking at their curiosity, Lu Zifei couldn't bear to refuse, so he said to Wu Pan: "You go to the kitchen and get an egg, a bag of salt, and a bowl of water." Wu Pan heard Mr.'s words, and the two little short legs stepped forward and ran excitedly.

Lu Zifei continued: "You've all seen lightning and thunder on weekdays, right? "I wanted to say that on the sea, you usually see the sail first and then the boat, but after thinking about it, I still gave up, the students here have never seen the sea, you tell them, they can't imagine it, lightning and thunder are often seen, it is easy to understand.

The student replied, "Yes."

Lu Zifei said: "Then have you ever thought about it, why is lightning always before thunder?" ”

The students were recalling the scene of rain, thunder and lightning in their minds, and what Mr. said was right, it was true.

Lu Zifei picked up the blackboard eraser and threw it out of the classroom, and Shen Kuo said excitedly: "Sir, I know, because lightning and thunder are the same thing, but we saw the light first, and then heard the sound." ”

is worthy of being a great scientist of the Song Dynasty, he can figure it out without any contact with physics, if he doesn't come with his memory, he may be thrown by others for more than a dozen streets.

"Shen Kuo is right, eat an extra egg for lunch."

Wu Pan held the eggs, the cook came over with water in the back, Lu Zifei asked everyone to gather in a circle, first put the eggs into the water, and naturally sank, and then he kept adding salt to the water bowl, and when he added more than half of it, a student said: "Look, the eggs are really floating." ”

Lu Zifei gave the salt in his hand to the students, changed a bowl of water, and let them experiment by themselves, without exception, the eggs are floating, this time Lu Zifei did not tell them the answer, and said: "You have to think about the principle of this thing, whoever comes up with it first, the teacher also has a reward, not an egg." ”

A simple little science makes many students addicted and intoxicated, which simply subverts their cognition, how can it be so, for the first time they are eager to understand the world, eager for more knowledge.

Lu Zifei is very satisfied with this effect, the only thing that rules this world is science, not those gods and ghosts, open the door in their hearts, whether it is a devil or an angel is their life.

A student raised his hand and asked, "Sir, I want to know if this is a science?" ”

Lu Zifei said with a smile: "Of course it is a science, this is a practical science, our ancestors called it Gewu, you can find the original in the study, you want to look at it yourself, this sentence comes from: Zhizhi is in Gewu, and then you know it." I prefer to call it physical science, sir. ”
