Otaku Engineer in Great Tang Dynasty Chapter 890: Engineering, new world! (End)

Out of nothing?

Why does this sound like a juggling?

By the way, everything Li Zexuan talked about in today's class made the students feel like they were juggling!

Throwing needles to calculate the ancestral rate, the colored glaze divides the sunlight, the double stitches become stripes, and the iron box just sent a letter, making them feel like they are dreaming, which is very unreal.

At this moment, Li Zexuan stretched the wire from the iron box into the water basin (this water basin is not made of wood, but made of colored glaze), and then filled two small colored glass tubes in the basin. Water, hold the nozzle, put it upside down into the basin.

Next, Li Zexuan inserted two enameled wires into two glass tubes.

"Look carefully, everyone, something interesting happened in a while!"

Li Zexuan raised his head and smiled. Then he called Mo Zhong and whispered a few words in a low voice. Mo Zhong led the way out. Li Zexuan pressed a button on the iron box next to him. Suddenly, the students in the auditorium It was discovered that the enameled wire in the glass tube started to bubble.

"Hey? Shan Chang is blowing bubbles for us?"

Cheng Chu heard it silently and whispered underneath.

The ancients would also blow bubbles, soak the saponaria in water, and cut a piece of bamboo, you can play bubbles, but the saponaria is too expensive, and few parents will let their bears and children be so violent, but Well, Cheng Chumo had a lot of fun when he was young.

About ten breaths later, there is already a glass tube in the basin that has all the water drained (the tube is hydrogen), but there is still half of the water in the other glass tube. Li Zexuan didn't care, let the gas in that colored glass tube overflow. When the water in the other colored glass tube was all drained, Li Zexuan pressed the button on the iron box again, and the enameled wire in the water basin no longer bubbled.

"Shanchang, this is electrolyzed water~?"

A person stood up and asked.

It is Wang Ji. The experiment of electrolysis of water is included in the first book of the "Chemistry" textbook, but he has only read the text description in the book, and has not seen a live demonstration, nor has he done it himself, because he does not Know where to get electricity! So until this time, he felt a little familiar.

"Mr. Wang has good eyesight! This is the electrolysis water experiment!"

Li Zexuan complimented, and then said to the students: "The two glass tubes in my hand now contain the gas that I just changed from using water. This is different from the air you breathe every day!"

"Cut, what can be different?"

The students all shook their heads in disbelief. In their opinion, the two colored glass tubes that Li Zexuan held in his hand did not contain any color at all, didn't they just contain two tubes of air? What's so strange?

Li Zexuan didn't make any excuses either. At this time, Mo Zhong had a short brazier and came in. Everywhere he went, the students gave in, because of the heat!

Li Zexuan was not too hot. He went forward to wrap his hand with a damp cloth, and pulled out a thin red wire from the brazier, and then reached into the water basin with the other hand. The thumb was buckled and filled with gas. He took out the colored glaze tube and said: "Then it is time to witness the miracle!"

When the students heard the words, their eyes widened, and they looked to this side intently.

I saw Li Zexuan loosen the thumb that blocked the mouth of the glass tube with his right hand, and quickly inserted the red wire in with his left hand.

"Hey~!"

The bright red iron wire suddenly burned in the glass tube, and it gave out a bright flame!

"I rely on it, iron can burn too? Am I right?"

Cheng Chumo yelled.

The rest of the students were also shocked, feeling incredible.

When the fire went out, Li Zexuan smiled mischievously, and then went to take out the other colored glass tube, and his left hand was the small burning stick that Mo Zhong handed over. The students didn’t know why, but The teachers of the chemistry department of the college all buried their heads and covered their ears.

"Bang~!"

The students only saw Li Zexuan put the wooden stick with the flame on the mouth of the glass tube, and then they heard an explosion that was not particularly loud, but definitely not too small.

"Fuck me!"

Except for the teachers in the chemistry department who had already prepared, everyone in the auditorium was taken aback.

Li Zexuan put down the test tube and clapped his hands. After everyone calmed down, he said: "Now you believe that I have turned water into two different gases~?"

The students looked speechless, they really believed in your evil, and they didn't know to tell us in advance before the explosion.

"The electrolysis water experiment recorded in the original textbook turned out to be true? The old man is a good one, Shan Chang is really a boon!"

Wang Ji said with emotion.

Li Zexuan smiled and said "Mr. Wang's false praise", then he winked at Mo Zhong, who quickly nodded and turned to go out. After a while, Mo Zhong moved in something half a person tall , Covered with red cloth. Mo Zhong moved the big baby to the lecture table, then stepped back.

Li Zexuan stood on the podium and said to the bottom: "Well, there are so many mini games that I will take you to play today. Next, I will show you something good!"

After that, he lifted the red cloth, a big blue ball, supported by the stand, stood on the table, and suddenly appeared in front of everyone.

"What is this? Two laps bigger than football?"

"You kid knows football!"

The students talked a lot, but Xiao Deyan from the Department of Geography stood up tremblingly and said: "Shanchang, this, this is..."

Li Zexuan nodded and said: "Mr. Xiao, that's right! This is the earth, it should be a model that imitates the earth! I call it a globe!"

After that, he looked at the students again and said loudly: "Classmates~IndoMTL.com~ The ground we step on is not flat. The saying that the sky is round and round is nonsense! We are all They all live on such a big ball. Specifically, your husband will tell you about it! From now on, I will put this globe in front of the Guanghua Building. Every time you pass by, you should take a good look at him and take a look. The world we live in is definitely a new world you have never known before!

Also, the little games I did with you earlier are all very meaningful. Don’t ask me about the specific principles. I hope that when you graduate from Yanhuang Academy, you can fully understand these questions. It's not in vain that I and the gentlemen of the academy have paid for you! Okay, get out of class is over! Go and rest! This concludes today's class! "

"Papa Papa~!"

At this moment, all the teachers and students couldn't help standing up and applauding Li Zexuan. Today's lesson is destined to be recorded in history! Moreover, this class really shocked them too much, and made them feel extremely grateful that they had chosen Yanhuang Academy in the first place! Otherwise, where would they go to learn such advanced knowledge!
