Chapter 101 Magical Water Purifier
Yu Fan, Chen Xingyang, and Guo Na were not in a hurry to make a move. They were also curious about the magic of this "magic water purifier".

A man wearing glasses and a white coat said: "Uncles and aunts, please stand back and give us a space to show." Then, two other men in white coats pushed the crowd back a little .These two should be assistants.

The bespectacled man who was the speaker unbuttoned his white coat with his hands, and flung it back chicly. It felt like a martial arts hero shaking his cape, making a handsome appearance.

But laymen watch the fun, and experts watch the way.Friends who work in the laboratory know that white coats have one and only one role in scientific research, that is, antifouling.But in film and television dramas, we often see many scientific researchers deliberately unbutton and shake their clothes when doing experiments, creating a sense of immortality.In fact, this is all ignorance and coolness.

With this simple action, Yu Fan can tell that the man with glasses is not professional.

The man with glasses said to everyone seriously: "We are affiliated to the Chinese Academy of Sciences, and today we are here to give you a science popularization activity about health." There are more and more people onlookers, and the people behind can't see it, so they push forward .

The man with glasses said: "As we all know, the water quality in and around lz city is very poor. The water we drink contains a lot of impurities and harmful microorganisms, which weakens people's immunity and makes them easy to get sick. There are also a lot of heavy metals in the water in the form of ions. Distributed in the human body, if people drink this kind of water for a long time, they will be poisoned by heavy metals and even cause cancer. Come on, let me ask you a question, what kind of water do you usually drink?"

Everyone has their own answers, "Our family drinks mineral water.", "Our family burns tap water."

Another voice said, "We don't drink water at home, we only drink soft drinks." Everyone roared with laughter.

The man with glasses also laughed. He pushed his glasses and joked: "The big brother who only drinks drinks at home, what kind of family is he? He raises pigs?" Hahaha, everyone laughed even harder.

The man in glasses shook his white coat back again, and said, "Well, no matter what kind of water you drink, we will do an experiment today. Let's see how the water you drink compares with the water purified by our magic water purifier." So." Then, the man with glasses asked the two assistants next to him to fetch two cups, one filled with local tap water and the other filled with water filtered by their water purifier.

Then the man with glasses took out a pen, and he told everyone that this is a high-tech pen called a TDS pen, which is used to measure the amount of impurities in water.He put the pen into the tap water, 187 appeared on the pen, and dipped into the purified water, 12 appeared on the pen.

At this time, the onlookers began to exclaim that the tap water they usually used had more than ten times more impurities than the purified water!
The man with glasses also told everyone very seriously: "It seems that the water pollution here is much worse than what we had expected." While talking, the man with glasses took out another instrument from under the table and put it on the table Above, the instrument is attached to four metal rods.The man with glasses said: "Maybe everyone is not very sensitive to this value, and you may say that I am cheating, so let's use this water quality tester to test it."

As he said that, the man with glasses inserted two of the four rod heads of the water quality electrolysis instrument into the two cups of water and energized it. A probe in the tap water began to bubble, and some flocs rose to the surface of the water with the bubbles. After two to three minutes, the glass The surface of the cup was covered with black and yellow floating objects, and the water in the cup gradually changed from colorless to yellow, blue and other colors. The pure water purified by their magical water purifier basically remained unchanged.

The onlookers began to talk about it. The tap water they usually use now looks like feces fished out of a cesspit, filthy and filthy.

Yu Fan watched all this intently.Chen Xingyang who was beside him quietly asked Yu Fan and Guo Na: "What's going on? Do you two have any clues?"

Yu Fan remained silent.Guo Na touched his chin and guessed: "I'm still thinking about the reason, but I think it should be the problem of those metal rods, which were tampered with in advance."

The man with glasses took out a "Chemical Substance Comparison Table", on which it was impressively written that different colors represented different chemical substances.Yellow: dissolved acids, silicon compounds, organic minerals, molybdenum, silicon, fluoride, other organic matter; green: arsenic (arsenic), mercury, lead, copper, sodium; blue: bacteria, viruses, carcinogens, organic phosphorus ( fertilizers, detergents and pesticides), etc.; red: iron and rust, bacteria; white: lead, zinc, mercury, inorganic salt dirt; black: heavy metals (zinc, lead, copper, chromium, manganese, cadmium);
Judging from the colorful colors of the water now, according to the man with glasses, the water is full of five poisons!The voices of the onlookers were getting louder and louder.

The man with glasses picked up the cloudy cup and said to everyone: "This is the tap water you usually boil? I want to ask, how do you usually drink this water? Who dares to drink one on the spot?"

Everyone was quiet, and they couldn't believe that the water they usually drank was like this.

The man with glasses went on to say: "Ordinary water purifiers can only purify some dirty things, but our magical water purifier is a high-level water purifier invented by the academicians of the Chinese Academy of Sciences through a lifetime of research and development. It contains our patented LHL Technology can purify the water to the extreme..." Well, well, the man with glasses began to amuse his things.

Chen Xingyang said quietly: "This grandson's style is different from the previous ones. He is following the scientific route, right? Old Yu, eh? Old Yu?" Chen Xingyang turned his face, but Yu Fan disappeared.Strange, where did Yu Fan go?
Guo Na saw that Chen Xingyang was looking for Yu Fan, she also turned her head, and found that Yu Fan disappeared without knowing when.

The man with glasses is still explaining his water purifier: "The water we have purified can not only keep everyone healthy, but also treat everyone's cervical spondylosis, lumbar spondylosis, coronary heart disease, etc. After today's science popularization, we have ten sets The magic water purifier can be given to everyone to experience at a discounted price and in the form of support.” The glasses man became more and more powerful, as if drinking their magic water could cure any disease.

The crowd also became more and more excited, and everyone seemed to be eager to try and prepare to snap up.

"It's almost done!" A loud voice came from the crowd, "I see, you are a bunch of liars!"

Everyone followed the voice and saw a young man wearing black-rimmed glasses.

That's right, that person is Yu Fan.
