Chapter 242 The Pentium Coke

A true master always holds the heart of an apprentice.

Mr. Li told Yu Fan and the others the whole story of the meal.It turned out to be the case.

Yu Fan asked: "So, this meal, you are actually testing us?"

Mr. Li laughed and said: "I'm sorry, yes. I told my old friends before that I met a supplier who was neither humble nor overbearing. I didn’t believe it, so I invited them all to let them see for themselves. I even gambled a pack of cigarettes with them, to see if you hate me.” While President Li was talking, the others also laughed.

Yu Fan was also happy, Mr. Li didn't expect to be so naughty.

Mr. Li: "At the beginning, we offered you a toast, but you drank it all and didn't refuse at all. This surprised me, and I thought I was going to lose. Fortunately, I sacrificed the 'depth bomb' in time. ', you finally couldn't bear to attack me with science. Haha, I still won. You all owe me a pack of cigarettes." Mr. Li said to his friends.

Yu Fan also smiled, and said, "Actually, when it comes to '扣' you, there is one more thing, I forgot '怪'."

Mr. Li said with interest: "Oh? What?" He picked up the Coke and took another sip while talking.

Yu Fan: "Mr. Li, I see that you have been drinking Coke tonight, and you have been eating Mentos mints. Actually, this is not appropriate."

When Mr. Li heard this, he choked up the Coke he drank, looking very funny.

Yu Fan casually took a Mentos candy from the table, and said to everyone: "Please make room, please sit back."

Everyone didn't know what Yu Fan wanted to do, but they moved back according to Yu Fan's request.

Under everyone's gaze, Yu Fan threw this Mentos mint into Mr. Li's Coke.Before everyone could ask questions, in an instant, the entire glass of Coke suddenly turned into foam and spewed out!The cola foam jumped out of the cup like a water dragon and fell to the table and the ground.

Yu Fan said to Mr. Li with a mysterious smile: "Mr. Li, do you think my foam is stronger than the foam in your workshop?"

Mr. Li patted his stomach in shock and said, "Isn't it? I ate Coke and Mentos mints together, and there was such a violent reaction? Then, isn't my stomach churning? It's going to explode? What the hell is going on? what happened?"

Yu Fan smiled and said, "It's not that serious, but it's best not to eat these two things together. The reason for this phenomenon is that Mentos mints promote the emission of carbon dioxide in Coke."

Mr. Li smiled and whispered to the people next to him: "Look, it's time for popular science."

Yu Fan said unhurriedly: "There are two main reasons why mentos candy can promote the release of carbon dioxide: first, the structure of the candy itself. The reason why there is a large amount of carbon dioxide in cola is because it is used in the production process. After the high pressure is applied and the bottle cap is opened, carbon dioxide is released from the cola, but this process is usually slow. Careful observation reveals that most of the bubbles are generated from the wall of the bottle (cup), because gas production usually needs to be attached to a certain surface Or on some particles, this phenomenon is called nucleation. Many people may have tried to insert chopsticks into carbonated drinks when they were young. At this time, bubbles will also adhere to the chopsticks. This is because the chopsticks provide a new surface. Become the 'nucleus' of gas production. If you magnify Mentos a hundred times, you can see that there are many small pores on the rough surface of these sugars. These porous structures make Mentos a good gas production 'nucleus' ’, a large amount of carbon dioxide can be attached to the surface of sugar to produce. And Mentos is denser than water, adding it immediately sinks to the bottom, and quickly generates gas at the bottom to facilitate the ejection of the top liquid.”

Yu Fandun continued: "The first reason is the surfactant in the candy. Although salt or sugar crystals with the same porous structure can produce hair eruption effects, they are far from the ability of Mentos. This is indeed related to The composition of Mentos sugar is related. Two substances are often used in the production process of Mentos sugar, one is gelatin and the other is gum arabic, both of which are natural surfactants. There are strong hydrogen bonds between water molecules function, the generated air bubbles must push away the tightly connected water molecules, and break through the encirclement to be released. Both gelatin and gum arabic contain glycoprotein components, and a large number of C=O bonds, NH bonds and OH bonds will destroy the water molecules themselves. Hydrogen bonding, so as to achieve the effect of reducing surface tension, that is to say, the enveloping network of newly formed bubbles is greatly weakened, thereby establishing an environment conducive to the formation of bubbles."

Yu Fan explained the principle of "Coke Burst" in great detail.Everyone was dumbfounded.Although Mr. Li's friends are also people who have seen the world, this is the first time they have seen people speaking in this way. "

President Li pointed at Yu Fan and said to the others: "See, this is professionalism, professionalism!"

Yu Fan felt that he might be a little wordy, and he didn't know if they could understand.Yu Fan smiled shyly, if Guo Na was present, he would definitely be able to sum up Yu Fan's words well.

Yu Fan, Wen Xin, and Cao Ben never expected that this Hongmen Banquet would be an unexpected surprise.It's just that everyone's happiness is different.Cao Ben was happy because Lao Yu finally didn't have to suffer so much to drink again.Wen Xin is happy because the success rate of this business is higher.Yu Fan was happy because what he insisted on was actually recognized by such a group of people.

The dinner ended in such a pleasant atmosphere.Yu Fan still drank a lot of wine today, and he almost fell when he got up just now (it might be because the Coke spilled on the floor was too slippery), but fortunately Cao Ben supported him.

Mr. Li sent Yu Fan and his party to the door of the hotel.Just as he was about to say goodbye, Yu Fan asked Mr. Li, "Mr. Li, I still don't know something. Why did you help me like this? Actually, it's completely unnecessary. And last time I really hurt your face. There must be other reasons for this, right?"

Mr. Li sighed, looked up to the sky, and said: "You are right, but I do have another selfish intention. My child is about the same age as yours, and he is also doing sales outside. I guess, He is the same as you. It is not easy for you young people to be in sales. I spent very little time with him since I was a child, and the relationship with him is very ordinary. He has not been back for many years. So I do this for him Accumulate some virtues, I hope he can go well outside, so that he can often go home and have a look when he is free. By the way, Xiao Yu, when are you going back to your hometown for the Chinese New Year?"

Mr. Li's words were thrown into Yu Fan's heart like a Mentos mint.There was a huge wave.

Yu Fan was calm on the surface and did not answer. He also stared at the sky.There is no smog in XA City today, and the bright moon in the night sky warmly embraces the hearts of every wandering child.
