Wasteland Development Diary.

Chapter 381 Electrolytic Cat Box
Shagang, Mushroom Forest Primary School.

Liang Xing looked at the students below the stage.

"Today we continue to talk about the application of chemistry in life."

"Students, what chemical reactions have you seen in your daily life?"

Students raised their hands enthusiastically. After more than a month of study and participation in experiments, chemistry has become a popular subject like a magic class.

"combustion!"

"Correct."

"precipitation."

"good."

"Decomposition reaction!"

"Photosynthesis... and corrosion!"

"Crystallize, explode!"

Everyone answered positively.

It’s not that these half-grown children have a strong interest in chemical knowledge.

Liang Xing just designed a little classroom trick - any student who participates in class discussions and answers questions will take part in his in-class experiments and may become Liang Xing's laboratory assistant.

Students may not be very interested in chemical theory, but they are very interested in the expansion, color change, explosion, combustion, and new substance replacement shown in chemical experiments.

That is why students always have heated discussions and many debates in Liang Xing’s class.

These children are young, and their perspectives and ideas are not bound by common sense. Occasionally, they come up with ideas that even Liang Xing finds very inspiring.

"...Okay, now it's time for the experiment."

Liang Xing picked up the wooden box at the door and placed it carefully on the podium.

He looked around at the 36 students sitting in the seats inside.

Everyone sat upright, their eyes filled with anticipation.

"Today is a very special experiment. I won't tell you what it does. You can tell me after observing it."

Liang Xing deliberately kept the secret.

He gently opened the box.

Inside is a transparent glass fish tank with an opening on the top and a rubber tube connected to a metal bottle. The tube and bottle on the left are painted red, while the one on the right is black.

A black rubber column was propped up at the bottom of the fish tank, with a miniature glass house fixed on it. It was connected to the left and right by thin metal wires, and it flickered like a lamp.

"Cat House!"

The sharp-eyed students have already shouted out.

"Electric cat, there is an electric cat!"

The students ran to the podium to observe further.

Everyone in Shagang knows that the company is breeding electric cats, but there are few opportunities to see the real thing in public.

Liang Xing waved the wooden stick in his hand and said seriously: "Old rules, keep your distance, ventilate the environment, and remember the safety regulations of the experiment!"

The students immediately opened the glass windows on both sides and stood outside the lines on the ground in an orderly manner, trying to look around. Some prepared telescopes to improve the clarity, while others stood on the table to observe from high above.

"This is indeed a cat house. Inside is an experimental electric cat I applied for from the company, Shining No. 3. I named it "Teaching Assistant."

"The teaching assistant has a kind and stable personality. He is a professionally bred and trained electric cat. He will not attack people and has good cooperation skills. Today is also the first time he has made a public appearance."

Liang Xing pointed his pointer at the tubes and bottles on the left, where red flame symbols were painted.

"What's the sign here?"

A student answered: "It is flammable and explosive!"

Another added: "It has to be stored separately! It can't be exposed to high temperatures or fire."

Liang Xing nodded and pointed the pointer at the bottle on the right: "What about this one?"

The skull on this bottle is very eye-catching.

Another student said: "It is extremely poisonous. You cannot open it or touch it casually. The substances inside will evaporate and kill people."

"Correct."

Liang Xing praised.

In every experimental class, he would patiently give warnings on safe operating procedures, which would help these students develop good habits of safe operation.

To make it easier for them to see at a glance, he also marked various instruments and equipment to help students understand the risks behind them.

Liang Xing took out a bucket of solution that he had prepared long ago and poured it into the glass jar.

He closed the lid when the liquid was half full.

"Observe carefully."

The cat house starts flashing faster as it starts to light up.

About ten seconds later, a ball of lightning flew out from inside. It flew back and forth in the water tank, making the metal wire in the entire glass tank emit bright highlights, illuminating the entire classroom.

"Wow!"

"So bright!"

"So much brighter than the Firefly mushrooms... Just like in the Emerald City!"

"This is an electric light! It's an electric light! Teacher Liang has recreated the life of an electric light!"

The students were talking at once.

Someone immediately noticed the key point: "The electric cat is swimming! Look!!"

Just as this sharp-eyed person described, the lightning cat "assistant" was swimming in the liquid in the water tank. Its running speed slowed down and it stabilized into the image of the Lightning Cat's head.

The electric cat swam around in the water and looked very comfortable.

"So electric cats like water!" "No, this water is not ordinary, it should be some kind of chemical solution."

A student suddenly said, "There are a lot of bubbles and gases coming out of the water. It's not as clear as ordinary water. It's a little turbid. There must be other substances in it."

"The generated gas went into both sides. The left side was flammable and explosive, and the right side was highly toxic... This is a chemical reaction, which decomposed or replaced the liquid."

Liang Xing was secretly surprised.

What a keen insight.

He turned his gaze to the student who was speaking: "What's your name?"

There are three classes in Mushroom Forest Primary School with a total of 147 students. Liang Xing has only been on the job for over a month and he still can’t recognize all the students.

"Teacher, my name is Chen Ji."

He knew this name.

In the eyes of two senior teachers, Diamond and Sun Chonglai, Heishugu 102, Chen Ji and Beita are three students who are very promising and excellent in all subjects. They are still assistant programmers in the program department.

Liang Xing gave him an encouraging look: "Chen Ji, based on your observations, tell me your judgment and speculation on this experiment."

Chen Ji is neither tall nor short, and his appearance is neither likable nor annoying. He looks very ordinary.

But when he spoke, there was a strange appeal that made people pay attention. The other students were all looking at him, and no one said anything bad.

Chen Ji walked along the cordon and looked around: "As far as I know, life can only remain relaxed and restful when it feels safe and comfortable."

"The electric cat did not return to the safest cat house, but floated in the solution of this container. It can be seen that it likes it here. This alone is of great economic value in the field of electric cat breeding."

"Since I can't communicate with the cat, I can only rely on daily interactions and long-term companionship to build trust and affection. This special pool makes it feel comfortable, like a playground for it."

Liang Xing smiled: "Not bad. Keep going."

No wonder this kid is so highly praised.

Indeed, he is very quick-witted.

Chen Ji stared at the glass tank for a while again, his eyes focused on the rubber tube behind the air outlet and the two metal cans at the end.

"This chemical reaction will produce two gases. Although inflammable and explosive materials are dangerous, the ignited gas can also be turned into a fuel or energy."

"On the other side are toxic substances. In medicine, toxic substances can cause abnormalities in living organs or change their microscopic properties, but many poisons are also raw materials for drugs."

"So I think the value of this experiment is threefold."

"It provides a completely new type of electric cat device that allows the cat to be more comfortable, closer to the owner, and maintain stability."

"Then it can also use the electricity from the electric cat to extract two chemical raw materials for processing and production."

Chen Ji touched his head and said, "Teacher, I can't say more. My knowledge is still too limited."

But this is already amazing.

Liang Xing felt bitter in his heart.

When I was 11 years old... I couldn’t even write properly. Talent is such a cruel thing.

However, as a teacher, I am lucky to have such a student.

"Student Chen Ji has done a great job. He made careful observations and had solid arguments."

Liang Xing said to all the students: "Now I will announce the answer. This experiment itself is not complicated. The chemical knowledge it involves is actually very basic."

"This is salt water, which is a sodium chloride solution."

"After electrolysis with the electric power of the electric cat, we can obtain sodium hydroxide liquid, as well as chlorine and hydrogen. These three substances are widely used as chemical raw materials in various fields."

"Sodium hydroxide, also known as caustic soda, can be used in textiles, printing and dyeing, papermaking, soap making, metallurgy, wastewater treatment and adsorption of heavy metal ions, as well as alumina production - this is also the area with the largest demand for caustic soda."

"Chlorine can be used for disinfection, bleaching, sewage treatment, and especially for drinking water disinfection, where it plays a big role."

"Hydrogen can be used to make rubber, convert energy, and be used in metal welding, pesticides, fungicides, herbicides, and is also an important chemical raw material for synthesizing ammonia, methanol, ethanol, etc."

"I have written this chemical formula before, but this is the first time I have applied it to an experiment,"

He looked at the students and said, "I just added an electric cat and everything has changed. The electric cat itself is continuously releasing energy to the outside world. We can't stop this process, so we can only find ways to use it reasonably."

"Chemistry is like this: find a catalyst, deduce the reaction process, find an environment where the result can be applied, and then replace what we need from nature."

"I can tell you that this device, the "Electrolytic Cat Box", has been recognized by the chairman, passed the invention review, and won the first prize of the Wasteland Invention Award. It will be announced soon."

The students in the audience were amazed, and many of them exclaimed that the teacher was so strong.

At this time Liang Xing felt a little embarrassed again.

I can't suppress my vanity... I can't help but want to show off to my students in advance.

He quickly found a way to change the subject: "Do you want to win awards and receive high rewards? Go study chemistry. This subject holds the secrets of wealth and power."

The students were encouraged to express their ideas one by one.

The classroom became noisy and lively again.

After class, Liang Xing put away the boxes and secured them on a hand truck.

Out of the classroom door.

He found a clawed pig outside with a scarf around its neck.

"Mr. Nightclaw?"

Liang Xing asked: "Why are you here..."

Night Claw said through the signal transceiver: "The Ministry of Electric Power is holding a meeting to report on the latest technology. You are a technical consultant and you must participate. The chairman will also attend this meeting. Hurry to Emerald City. I have already notified Xie Dongshan, you are the only one missing."

"Okay. But I still have to put away my electrolytic cat box..."

"Take them together, let's go."

"it is good."
