Making a pair of sunglasses is really not an easy task. First of all, you need to find a lot of raw materials, and without polypropylene, you can only find metal to make glasses frames. However, Shang Wen found another material, natural horns. This is a very good frame.

Then it's a matter of looking for some fine iron powder, copper powder. If you want to make color-changing glasses, you probably have to look for silver halide. Shangwen also had to be extracted from industrial salt. This requires a lot of chemical appliances. What is extracted from industrial salt is only a mixture, not the one you need most. Shang Wen wrote in the notebook with all his strength in his left hand. And Yingyu watched Shang Wen's twisting movements like watching a funny performance.

"Hehehe. You're hilarious. Yingyu said with a smile.

"He also said, let you write, and you can't write. I had to do some of the chemical equations myself. Shang Wen said.

"The chemical equation, oh. It's the ones you draw. Just like those alchemists? Yingyu asked.

"Drawing symbols?" Shang Wen looked at Yingyu questioningly.

"That's right. It's just a drawing, you see. Ying Yu said and pointed to the chemical equations that Shang Wen had written in his notebook.

"That's ・・・・・・・ forget it. If you say draw a symbol, you will draw a symbol. Shang Wen said helplessly.

"You draw a talisman, and I will be a priest for you. Conjure these things up according to the symbols you draw. Yingyu said and began to take out some glassware.

"Wait." Shang Wen exclaimed.

"What's wrong? Don't believe me, a monk. Yingyu said.

"No, no, it's because silver nitrate is used in the chemistry experiments we are going to do today. Silver nitrate is corrosive. And poison. Shang Wen said.

"Laughing sour silver? What is this, and poison. Yingyu asked suspiciously.

looked at Yingyu who didn't know anything. Shang Wen knew that he would let a person who didn't know anything come to the laboratory. That's a very dangerous thing. He is not afraid that Yingyu will hurt himself. Instead, she was afraid that her ignorance would cause uncontrollable results. Moreover, a certain amount of electricity is used.

"It's silver nitrate. That thing is poisonous in itself. It's not that I don't let you, it's that this kind of thing will invade the skin. Allow the skin to fester. Shang Wen could only make it up by himself.

"Ahh Yingyu repeatedly saw what silver nitrate looked like after corrosion.

"You're telling the truth." Yingyu asked.

Shang Wen didn't say anything, nodded in agreement.

"Well, then I'll see what you do. I watched from afar. "Yingyu seems to be very afraid of experiments. Especially silver nitrate.

"Hey, hey. However, when I extract silver halide, I get another by-product. This kind of by-product can draw you all at once. Shang Wen said.

"Draw me! You know how to draw. How I don't know. You find that you idiot doesn't know how much stuff is hidden in your head. And. Yingyu looked Shang Wen up and down.

Don't look at me like that. Shang Wen looked at Yingyu and looked himself up and down and said.

Say. What else are you hiding from me? What else would you do. Give me all of them today. I'll see how many tricks you can come up with. Yingyu pointed at Shang Wen with her finger and said.

"Oops. Oh, my God. I have nothing to hide from you. Shang Wen said with an innocent face.

"How do you explain the matter of drawing?" Yingyu asked.

"When I paint, I'm talking about photography. It's just like the painting. I'll take you down. Shang Wen explained.

"Take a picture? What are you doing in the mirror and looking at me? Such a photo. You can draw me. Yingyu asked.

Shang Wen listened. Yingyu thought a little way.

"Yes. It's just a photo. Draw you on a piece of paper. It's more real than a real person. Shang Wen said.

"Hmm." Yingyu looked at Shang Wen. This guy is so strange. There really is this thing. As she spoke, Yingyu looked at Shang Wen again. Think about it though. This nerd is no ordinary person. Maybe there is. Tentatively. Believe him once.

"What do you think I'm doing? Don't do it yet. Can't do it. I'll skin you alive. Yingyu returned to that strong woman attitude.

"Then don't make trouble. It's high temperature again. Electric again. I can't get it. Disfigured. Shangwen warned.

"I'm not willing to help with that yet. Hurry up! Yingyu pretended to sit on the sofa and watch Shangwen do experiments.

Shang Wen was not flexible with one hand. I can only reluctantly.

Shangwen first made silver nitrate. Silver nitrate needs to react with 65 percent nitric acid. But silver contains certain impurities. Shangwen needs to use electrolysis to deal with it. The advent of batteries can store electricity. The voltage has been known to the Qin people. It's like, after the Qin people understand the air pressure. Start drawing inferences. Water has water pressure. Electricity that. There is definitely voltage. This is when the simple voltmeter appeared. Besides. There are also transformers. At present, it can only be lowered. It cannot be pressurized. And the workmanship is extremely crude. This thing currently exists in the lab.

It took an hour. Shangwen extracted a bottle of silver nitrate. Yingyu was very impatient. I changed the various sitting positions again. Then it's time to lie down. Lie down and lie down. Or don't get up. can see that Shang Wen is doing this again. It's that again. He sat down again.

Shang Wen was busy extracting bromine. Mainly used for experiments. The practical significance is not very great. Mainly used for research. When seawater has gone through several crystallizations to produce salt, it can no longer produce salt. At this time, there is bromine in the solution. But usually this is disposed of as wastewater.

"Okay, no?" Shangwen is heating up. Saturate with salt water. Yingyu couldn't wait any longer, so she came up and asked.

"Not yet. And so on. Shang Wen said.

"When will it be over! Never mind. I'll come back in the afternoon. "Finished. It's about to leave. But random returns. Sit back down.

"Why are you back again?" Shangwen began to melt the glass. It was decided to add iron powder, copper powder to the glass first. These are the absorbing materials of the lenses.

"It's boring." Yingyu replied very simply.

"It's boring to see you. Give you a fun one. As he spoke, Shang Wen took out a glass rod and fired the Mitsubishi mirror.

"What's fun?" When Yingyu heard this, she immediately became interested.

"Rainbow has never seen it. You take a prism and go to the sun. You can see the rainbow. Shang Wen said.

"Really? Doesn't the rainbow appear after it rains? Yingyu asked.

"There you have it. You let it appear whenever you want. It listens to you. Shang Wen said.

"That's great," Yingyu said, clapping her hands. Shangwen is being processed.

"Bring it." Yingyu reached out.

"Wait a minute. I'll quench it for you and turn it into fiberglass. Shang Wen said and began to heat up. Yingyu stepped forward and waited.
