I cried countless students in the exam

Chapter 118 Manufacture of Weather Changes
The eyeballs of all the people in the classroom are staring round!

Create lightning between heaven and earth?
Like the protagonist in an online novel, controlling thunder and lightning?
No one thought that Shen Ping, who was originally standing silently on the podium, would say something so shocking.

The female professor of the chemistry department showed a look of astonishment on her face, "This... this is a bit interesting."

They can also use chemical reagents to create scenes similar to lightning and thunder, but the students in the classroom don't know that the chemistry content taught by Professor Li in the textbook is essentially for ordinary chemistry teachers to create!
Professor Lao Li's cloudy eyes stared at Shen Ping on the podium for several seconds, and then he couldn't help laughing, "Okay! Since you can say this, it means that you are absolutely sure. Alright!" After a pause, he continued: "It didn't disappoint me, today's trip was not in vain, well, Shen Ping, even if you can't get it out in the end, I won't say anything about you."

Can't get it out?Still won't say anything about me?
No one understood what Professor Lao Li meant.

Shen Ping also saw Professor Li standing at the back of the classroom, and said with a smile, "Why can't it be done?"

Professor Lao Li couldn't help laughing: "Because what I said in the chemistry textbook, although I explained the principles of atmospheric chemistry, I didn't give how to create these weather changes. Now he just said that, and didn't do it." Come out, that's why I said that even if I can't get it out, I won't say anything more."

That's what it meant.

But when everyone suddenly realized, Shen Ping raised his head and smiled, "You think I can't do it, this is just your personal subjective opinion, it doesn't mean that I really can't do it, Professor Li, even if you say so." I can't do it and you won't say much, I don't feel very comfortable listening to this. Hehe."

Everyone in the classroom was stunned.

What does it mean?
Publicly refute the professor of chemistry department of famous university?

Professor Lao Li couldn't help being happy, "What? You still can't listen to it? Then try to make what you just said and what you want to show in this chapter, and show it to the students. Let's see."

Shen Ping smiled and said, "What a coincidence, I thought so too."

Old Professor Li narrowed his eyes, "Then let's start directly!"

Here, Shen Ping agreed, and everyone in the classroom immediately stopped talking, and all their eyes fell on the podium. Everyone wanted to see how Shen Ping created an existence similar to lightning.Everyone believed it, because Professor Lao Li was a professor of chemistry at a prestigious university, while Shen Ping was just a high school student who hadn't even taught chemistry, so it was clear at a glance who would win.

Everyone knows that Shen Ping will definitely not be able to create it.

However, Shen Ping smiled slightly, then lowered his head, followed the [chemical experiment operation steps] in his mind, took out two small bottles of chemical reagents, and slowly poured them into the round bottom flask.

The round bottom flask has changed.The transparent round-bottomed flask became pitch black at this moment, even mixed with a faint red, and then the red became more and more intense, until it was as thick as human blood.

Immediately afterwards, the red liquid like human blood became more intense, and a dazzling silver-white light flickered continuously.

Finally, the silver-white light burst out like a thread, piercing the classroom like a sharp sword.

That shining arc went all the way up inside the round bottom flask to the edge of the bottle mouth. In an instant, the entire podium was enveloped by a burst of white light. Combined with the dark and scarlet liquid like human blood, it was like the most peculiar light. Just like the stereo, it glowed red on the podium.

The sound of thunder and lightning sounded just right, like a lion roaring, covering the entire classroom!

At this moment, Shen Ping is like the protagonists in online novels, controlling thunder and lightning!

……

Oh my God!
This picture... is it really successful after lying down?

You, this scene of lightning and thunder, was really created by you?
Seeing the scene of lightning and thunder on the podium, everyone in the classroom was dumbfounded!

Even Professor Li was stunned, and subconsciously said: "You have simulated the lightning scene, so how do you create the chemical content in the next chapter?"

"The rest is not difficult." Shen Ping responded immediately, then looked at the students in the classroom, and reminded: "Students in the first three rows, all back up, squeeze first with the students in the four rows behind, and cover your mouth. Shut your ears. Because the next chemical operation is a little dangerous."

While speaking, he took out another solid red piece and placed it on the podium. After all the students backed away, he took out a feather from his trouser pocket and touched the solid red piece...

"boom!"

The pink powder exploded in an instant, floating everywhere in the first three rows of the classroom, and the sound of the explosion was deafening.

"Students, this is nitrogen triiodide. It is a deep red solid. Because of its weak stability, it is a highly sensitive explosive. In a dry state, light touch, such as lightly with a feather Touching the ground, air flow, and even a sudden increase in light will cause an explosive decomposition reaction to occur immediately, and the sound is loud," Shen Ping explained.

……

Professor Lao Li nodded, and then continued to ask: "What about the remaining two chemical experiments?"

Without any nonsense, Shen Ping directly took out a kind of water-absorbing resin, and then looked at Kang Xue, "Director Kang, bring me a pot of hot water." The stunned movement of the students.

He lifted the kettle, poured out a small cup of hot water, and poured it into a round-bottomed flask also filled with water-absorbing resin.

In an instant, all the hot water in the cup disappeared, and then countless white fluffy substances came up, looking like snow.

Shen Ping looked up at the students, and said with a smile: "Students, this water-absorbing resin is called sodium polyacrylate, which is generally used in daily life to enhance the protein adhesion of edible flour, as well as bread, noodles, sauces, Cream, fruit juice, wine, ice cream, and even used in movie shooting and interior decoration... You can try it yourself after you get home, but you must pay attention to avoid contact with skin and eyes, and rinse with plenty of water after contact."

At this moment, deep shock appeared on Old Professor Li's face!Can this be made easily?
When Professor Li saw that he was dying, he could only resort to a trick, "Then what are you going to do with the flame in this chapter of the chemistry textbook?"

Who knew that Shen Ping didn't feel any difficulty at all, and looked at all the students in the classroom with ease, and said with a smile: "Students should have read an online novel, right? The protagonist of this novel is surnamed Xiao, and he was born On that day, the holy flames fell from the sky, and the walls of his courtyard were burned down by the flames, so his father, the patriarch of the Xiao family, gave him a mighty and extraordinary name!"

　Today's second update, please collect, recommend, and reward.In addition, there are relatively few updates in these two days because of the third anniversary of grandma on the 21st, so I have to prepare in advance, please forgive me.
