"Chemistry?" The master laughed contemptuously, "Everything is made up of elements, and those who master the elements will master it。。。。。。 ”

"It's not wine at all, is it? Yu Fan interrupted the master's blind force.

A panicked expression appeared on the master's face instantly, but for just a second, he quickly retracted again, scratched his neck, and pretended to be calm.

Yu Fan continued: "Scratching my neck is to alleviate the embarrassment of the lie being exposed, it seems that I am not wrong." I guess this purple bottle of wine is a potassium permanganate solution, right? ”

As soon as the master changed the way of the worldly master just now, he began to refute: "Ordinary people are talking nonsense, how can you wait for fools。。。。。。 ”

"And these seemingly empty transparent cups aren't really empty, are they?" Yu Fan interrupted the master's words again, for those who are crooked and heretical, the best way is to shut them up.

The followers of the master began to support the master, and some people continued to insult Fan.

Yu Fan had long expected what kind of risks he would face in exposing scammers in such a way.

You have broken the faith of many devout people, and they naturally want to break you too.

Yu Fan continued: "The 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 mistakenly think that the cup is empty. When you put the potassium permanganate solution into the cup, a chemical reaction takes place, and it naturally becomes a colorless liquid. That's your first trick, conjuring up water! ”

The audience was a lot quieter, 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 also very easy for you to conjure milk." Just add a very small amount of sodium metasulfite solution and barium chloride solution in advance to the empty cup. In the first step of the reaction, the solution contains sulfate ions, which are then reacted with barium ions to form water-insoluble barium sulfate. It takes the shape of milk. ”。

Yu Fan finally said: "You finally conjure up a soda." It is nothing more than the addition of sodium metasulfite and sodium carbonate in advance. After potassium permanganate is added, the sulfuric acid produced by the pre-reaction reacts 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 at all to make such a gorgeous stage effect, admire. ”

It may be the first time that the master has been directly exposed in this way, jumped up angrily, pointed at Yu Fan and scolded: "Little rabbit cub, what you just said is all your own fabrication, how can you prove that what you said is right?" ”

Yu Fan: "Master, you are mistaken, the person you want to prove is not me, but you!" ”

Yu Fan pointed at the master with one hand, and the master was so frightened by this momentum that he took two steps back, and then Yu Fan pointed to the cup and said, "Master, if you want to prove me wrong, please drink this bottle of your "wine"?" ”

The master was blinded.

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

At this time, Chen Jiaoyang jumped on the stage and shouted: "Don't move, police!" ”

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

Chen Xiangyang thanked Yu Fan and said, you were so handsome just now, without you talking about it, I am afraid it will be difficult for these brainwashed people to be convinced.

Yu Fan smiled, picked up the microphone again, and said into the microphone: "Officer Chen, you are polite, you have caught the master, and his minions can't be let go, you use your latest automatic smartphone chat history detector to detect the mobile phone chat history of all of them within five minutes, and you can immediately find the nursery in the crowd in the venue." ”

There was another stir in the room. Chen Jieyang looked confused, what kind of automatic smartphone chat history detector? I've never heard of it.

Yu Fan quietly pulled Chen Jiaoyang at this time and said: "That's how I deceived them, I observed that there are monitors in all corners of this venue, and there are water droplets in the middle." When fear comes, people will react in their favor as soon as possible. You will take a look at the surveillance, when you appeared on the scene just now, which people chose to escape for the first time? Look at what I said just now, who took out their mobile phones to delete the chat history for the first time? All in all, it should be very beneficial for your investigation work, and you should finish work early. ”

Chen Jieyang suddenly realized, but said half-jokingly: "I already knew, haha." ”

Yu Fan also snorted and said, "Okay, go back and rest, and play together another day." ”

Chen Jiayang said goodbye to Yu Fan. Chen Jieyang's colleague next to him came over and asked, "Old Chen, who is this guy?" ”

Chen Jieyang nodded slightly, his face was happy: "We call him a psychochemist." ”
