Chapter 4 Expose the Master
"Chemistry?" The master smiled contemptuously, "Everything is composed of elements, and those who master the elements..."

"This isn't wine at all, is it?" Yu Fan interrupted the master's nonsense.

There was a panic expression on the master's face for a moment, but for just a second, he quickly restrained himself, scratched his neck, and pretended to be calm.

Yu Fan continued: "Scratching the neck is to ease the embarrassment of being exposed. It seems that I am right. I guess, this bottle of purple wine is potassium permanganate solution?"

The master changed his style of being an expert just now, and began to retort: ​​"Ordinary people are talking nonsense, you are so stupid..."

"And these seemingly empty transparent cups are not really empty, right?" Yu Fan interrupted the master again, and the best way for those who speak heresy is to shut them up.

Some disciples of the master started to support the master, and some people continued to abuse Fan.

Yu Fan had long anticipated the risks of exposing the liar in this way.

You shattered the faith of many pious people, and they naturally want to shatter you.

Yu Fan continued: "Sodium metasulfite solution is colorless, you only need to add a little bit to the bottom of the cup, and use the illusion of the bottom of the cup to make people think that the cup is empty. After you pour the potassium permanganate solution into the cup, something happens. After a chemical reaction, it naturally becomes a colorless liquid. This is your first trick, water is produced!"

It became much quieter off the stage. In fact, many people didn't know what Yu Fan was talking about, but they were impressed by a calm young man on stage.

Yu Fan said again: "It's very simple for you to make milk. Just add a small amount of sodium metasulfite solution and barium chloride solution to an empty cup in advance. Through the first step of reaction, the solution contains sulfate ions , and then react with barium ions to form water-insoluble barium sulfate. It forms the appearance of milk.".

Yu Fan finally said: "You turned out soda in the end. It was nothing more than adding sodium metasulfite and sodium carbonate in advance. After adding potassium permanganate, the sulfuric acid generated in the pre-reaction reacted with sodium carbonate to form carbon dioxide gas. Master Jielu , I’m sorry, I’m going to expose the master, your design is very ingenious, and you don’t need any magic skills to create such a gorgeous stage effect, I admire you.”

It may be the first time that the master has been directly exposed in this way. He jumped up angrily, pointed at Yu Fan and scolded: "Little brat, what you just said was all fabricated by yourself. How can you prove that what you said is right? of?"

Yu Fan: "Master, you made a mistake. The person who needs to prove it is not me, but you!"

Yu Fan pointed at the master with one hand, and the master took two steps back in fright. Yu Fan then pointed to the glass and said, "Master, if you want to prove me wrong, please put your bottle of" wine " How about drinking it?"

The master is confused.

Yu Fan: "Master, potassium permanganate is highly poisonous. I'm afraid that after you drink it, you will only be able to preach to people in another world."

At this time, Chen Xingyang jumped onto the stage and shouted: "Don't move, police!!"

There was a panic off the court, but it was quickly controlled by Chen Xingyang's colleagues.

Chen Xingyang said gratefully to Yu Fan, you were so handsome just now, without you talking so much, these brainwashed people might not be convinced.

Yu Fan smiled, picked up the microphone again, and said into the microphone: "Officer Chen, you are polite, you have caught Master, and his subordinates must not let him go, use your latest automatic smart phone to chat The record detector can detect the mobile phone chat records of all of them within 5 minutes, and immediately find the babysitter mixed in the crowd at the venue."

There was another commotion in the venue.Chen Xingyang looked confused, what kind of automatic smartphone chat record detector?Never heard of it.

At this time, Yu Fan quietly pulled Chen Xingyang and said: "I just lied to them like this. I observed that there are surveillance cameras in the four corners of the venue, and there is also a water drop surveillance in the middle. When people are afraid, they will immediately act against themselves. Favorable reaction. You will take a look at the monitoring later. When you came out and revealed your identity just now, who chose to run away the first time? Then look at who took out their mobile phones to delete Chat records? Taken together, it should be very beneficial to your investigation work, and you should call it a day and get off work."

Chen Xiangyang suddenly realized, but said half-jokingly: "I knew it a long time ago, ah ha ha ha."

Yu Fan also took a breath and said, "Okay, go back and rest, let's play together another day."

Chen frame Yang said goodbye to Yu Fan.The colleague of Chen Xiangyang next to him came over and asked, "Old Chen, who is this guy?"

Chen Frameyang nodded slightly, with an amused look on his face: "We call him a psychochemist."

　The curtain of the stage of life may be opened at any time, the key is whether you are willing to perform or choose to avoid. ——sodium metasulfite
