The laboratories of Binhai Middle School are open to the public, and you can enter and exit freely as long as you use your student ID.

Moreover, the laboratory foundation of Binhai Middle School is very complete, and it is a multi-functional laboratory integrating biology, chemistry and physics.

It was already noon when Yang Fan came to the laboratory, and most of the teachers and students in the school were on lunch break at this time, so the laboratory was empty and there was no one at all.

In the laboratory, there are various microscopes, specimens, circuit boards, semiconductor integrated boards, and pungent chemical reagents.

Yang Fan looked at the microscope on the table, and the corners of his mouth couldn't help but hook up a smile, at the beginning, when Yang Fan was in charge of the underworld, a bearded gentleman came to the underworld, this gentleman was very strange, as soon as he came to the underworld, he threw two iron balls with different qualities from the same height in the air, and then proved that the two iron balls would land at the same time.

Mr. Beard also preached in the underworld that if you ignore the air resistance and throw the iron ball and goose feathers from the same height, they will also hit the ground at the same time.

After that, the bearded gentleman made a strange lens out of a thick lens, which he could put in front of his eyes to see far away.

This bearded gentleman was none other than Galileo.

Because Galileo violated the ideas of the pope, his later life was particularly miserable, and even until his death, Galileo still had some doctrines and advanced ideas that were not published to the world.

However, after Galileo went to the underworld, he hit it off with Yang Fan at first sight and handed over all the scientific knowledge he had mastered to Yang Fan.

Yang Fan remembered that after he mastered Galileo's scientific knowledge, he also built a super telescope in the fairy world, which made clairvoyance embarrassed.

Yang Fan shook his head and didn't think about it anymore, he turned around, but saw two peas again.

These two peas couldn't help but make Yang Fan fall into deep memories again.

At the beginning, Yang Fan was in charge of the underworld, and a priest with rimless glasses came to the underworld.

As soon as the priest came to the underworld, he planted peas all over the underworld, saying that he was going to do some pea experiment.

Eventually, the priest developed a genetic theorem based on the growth of peas, which later became known as the Mendelian pea experiment.

Mendel's experiments with peas in the human world helped to understand genetic inheritance, but Mendel came to a deeper understanding after his death and came to some other, more esoteric conclusions.

But in the underworld, no one could discuss the doctrine with Mendel, and in the end, Mendel met Yang Fan and told Yang Fan all the scientific mysteries he had mastered.

After Yang Fan learned it, he also used the genetic inheritance theorem studied by Mendel to make the extinct divine beasts in the immortal world reappear in the world, creating a good story.

……

Yang Fan's eyes kept sweeping over the various artifacts in the experiment, and almost every artifact in the experiment had a deep memory in Yang Fan's mind.

Yang Fan retracted his thoughts, didn't think about it anymore, directly took a bench, sat down, and then took an aluminum sheet and some iron pieces from the experimental table.

"Yang Fan, what are you going to do?" On the side, Xu Wanqing asked curiously.

"I want to develop new energy. Yang Fan didn't hide it.

Lin Feiyan was slightly stunned, and hurriedly said, "Yang Fan, wait a minute, let me start a live broadcast!"

Lin Feiyan has been playing live broadcasts recently, and she doesn't have many fans in her live broadcast room, just more than a hundred.

Lin Feiyan quickly opened the live broadcast room, and then said hello to the fans in the live broadcast room: "Hello everyone, today's live broadcast content is live broadcast research and development of new energy!"

"I'm slot!Anchor 666, I didn't expect the anchor to be not only beautiful, but also very smart, and even play with scientific research and creation, he is really a pillar of the country and a flower of the motherland!"

"Anchor, even if you are beautiful, you will also develop new energy, and you will not let people live?"

"Anchor, what kind of new energy is it?"

……

Although there are only more than 100 fans in Lin Feiyan's live broadcast room, these more than 100 fans are all loyal fans, and the stickiness is very high.

"Haha! I don't have the ability to develop new energy, but this is the one who wants to develop new energy today. Lin Feiyan smiled as he moved the camera towards Yang Fan.

However, Yang Fan frowned, and said in a deep voice: "Feiyan, don't slap my face, if you want to broadcast live, broadcast the R&D process live." ”

Yang Fan shook his head helplessly, he still wanted to study quietly in school for a few days, and he didn't want to be too high-profile.

Lin Feiyan immediately understood, nodded, and directly aimed the camera at Yang Fan's hand, and at the same time, Lin Feiyan quickly changed the name of the live broadcast room to: "Live broadcast research and development of new energy." ”

"Anchor, what's the matter with your friend? Is he too ugly to show his face?"

"Fart upstairs, look at that hand, how beautiful it is, it's just a hand-controlled party welfare time, so good?"

"This live broadcast room is called live broadcast research and development of new energy, slot, this awesome blow is a bit big!"

"You are also developing new energy, why don't you go to heaven?"

……

After Lin Feiyan opened the live broadcast room, some tourists soon poured in, and the barrage in the live broadcast room kept brushing.

Yang Fan didn't look at the live broadcast room at all, but picked up the aluminum sheets, iron sheets and a lot of metal materials in his hands.

Yang Fan carefully wrapped the concentrated sulfuric acid liquid in a piece of inert metal, and then injected a variety of different liquids into the inert metal, so that the liquid in the fast metal can circulate and react, produce positive and negative different ions, move directionally, and form an electric current.

However, this was just the beginning, and then Yang Fan applied some black chrome coating to the surface of the metal to ensure that the whole metal has good heat absorption.

"I'm Cao! anchor, your friend is really doing something like that!"

"The directional movement of electrons produces an electric current, which is still written in my chemistry book. ”

"Anchor, your friend is a great god. ”

……

The barrage in Lin Feiyan's live broadcast room was flying, and the number of people in the live broadcast room was increasing, and soon, the number of people in Lin Feiyan's live broadcast room had exceeded 10,000.

However, Lin Feiyan frowned, she couldn't understand what Yang Fan was doing at all, even the academic bully Xu Wanqing and Liu Shi's faces became solemn, they could get a glimpse of the doorway, but they really couldn't say why.

In front of the test bench, Yang Fan's expression was focused, with a small wrench in his mouth, and some precision movements were carried out quickly in his hands.

Yang Fan used very fine copper wires to quickly wrap the inert metal, and then put a few small magnets around it.

In the end, Yang Fan held a small piece of precision iron and carefully wrapped the magnet and the inert metal wrapped around the coil, and the corners of his mouth finally showed a smile: "New energy button battery, it's done." ”
