Director Jiang was directly dumbfounded: "Is it so fast?" Seconds? ”

Director Jiang's heart was stuffed: What should I do if I feel sorry for money?

Director Jiang said depressedly: "You say." ”

Sweet image explains: "The reason why the popping candy can beat in the mouth is because the high-pressure carbon dioxide that is sealed in the popping candy is released as the syrup melts in the mouth, breaks the seal, and is released. ”

Netizens in the live broadcast room pricked up their ears.

[What, hahaha, sealed carbon dioxide? 】

[Could it be that carbon dioxide is the supreme of the demon race, which is sealed in the jumping candy, just waiting for our mouths to help it break the seal? ] 】

[Ten miles of marshmallows won't be, right? ] 】

Gan Tian looked at the barrage and said: "The image is a little bit, it can indeed be understood in this way, this is due to the special production process of Jumping Candy."

In the process of making jumping candy, it will be sent to a high-pressure chamber dozens of times higher than the normal atmospheric pressure, the high-pressure chamber is filled with carbon dioxide, with the stirring and cooling of the syrup, the high-pressure carbon dioxide will be trapped in the syrup, and when the cooled syrup is taken out of the high-pressure chamber, the cooled syrup will be broken by the high-pressure carbon dioxide inside, and broken into pieces of irregularly shaped jumping candy, which is what you see when you buy it.

However, even though most of the high-pressure carbon dioxide has escaped after leaving the high-pressure chamber, a lot of carbon dioxide is still sealed in the irregular crushed sugar.

We buy popping candy and send it to our mouth, and the carbon dioxide that is sealed in the popping candy will beat in our mouth when it is vaporized by heat and has a thrust effect, it's as simple as that.

Mothers in the live broadcast room don't have to worry, the carbon dioxide released by a pack of popping candy is not as much as the carbon dioxide released by a bottle of Coke, which is not enough evidence.

If you don't believe me, you can put popping candy in the water and see if it will bubble in the water, which is carbon dioxide. ”

So that's the case?

Netizens in the live broadcast room said: Thank you~ I understand!

Gan Tian said: "When it comes to the clever use of carbon dioxide, the fritters that everyone eats in the morning are also an example. ”

Director Jiang asked: "Churros are also clever use of carbon dioxide, how to say?" ”

Gan Tian blinked: "Is this the second question?" ”

Director Jiang: "!! ”

Gan Tian said lazily: "If you don't pay, forget it." ”

Netizens in the live broadcast room: [Hahaha, knowledge is power, knowledge must be bought with money, isn't this much better than selling underwear? ] Director Jiang is going to break the bank, and I feel pain for Director Jiang across the screen. 】

Director Jiang gritted his teeth: "Okay, you tell me." ”

"Alum undergoes a chemical reaction at high temperatures to produce a lot of carbon dioxide," Tian said. In the process of making fritters, alum is added and fried in an oil pan, and the carbon dioxide produced at high temperature will make the fritters expand rapidly in a short time, so alum can be used as a leavening agent.

When you buy fritters, you can observe, those fritters that seem a little fat and have large pores, must be added with alum, and the structure of fritters without alum is relatively tight, if you don't want to eat alum, you can choose fritters with a tight structure, but in terms of taste, fritters without alum taste good, and fish and bear's paws cannot be both. ”

Director Jiang wiped his head: "So that's the case." ”

Gan Tian stretched out his hand: "I have already answered two questions, a thousand yuan, the trouble is settled, it is best to end one question at a time." ”

Director Jiang: "What's in a hurry, I won't give it." ”

Gantian: "Then who knows?" ”

Director Jiang: "!!! ”

"I'm a well-known director in the entertainment industry, can I still owe you this money? Do you know how many male and female stars in the entertainment industry are rushing to have a good relationship with me, and they don't need money to come to my movie for a role? ”

Gan Tian raised her eyebrows and said honestly: "So, I don't mix in the entertainment industry, we are a one-time deal." ”

In the live broadcast room, netizens looked at Director Jiang's deflated appearance, and they were going crazy with laughter: [Hahaha, I'm going to die of laughter, I've never seen Director Jiang deflated like this, the world is retributing, let you lick a passerby~~~]

Director Jiang groped all over his pockets, but he didn't touch a dime, he angrily asked Gan Tian to add him to WeChat, and he WeChat transferred it to her.

Gan Tian took out his mobile phone and added WeChat with Director Jiang.

When he added WeChat, Director Jiang was sharp-eyed and saw a familiar avatar, and when he took a closer look, Gan Tian had already taken back his mobile phone.

Director Jiang rubbed his eyes, is it an illusion?

How did he see that there was Gao Shen among his sweet WeChat friends?

In the live broadcast room, netizens are still swiping the screen to ask various questions.

Director Jiang could only temporarily suppress the questions in his heart, watch the live barrage, and continue to select interactive questions.

[@十里棉花糖, when I was a child, I watched my grandmother dye her nails with impatiens, and she also used alum, which looked better than the one I dyed at the nail salon~ What is the principle of that? 】

[One world, one grandmother, my childhood! 】

[My grandmother also got it, mashed the henna, added alum, and then applied it to the nails, wrapped it in mulberry leaves overnight, and woke up the next day to open the leaves, and the fingernails were dyed beautifully. 】

[Grandma also got it for me, and said that I can't fart, otherwise it won't be popular, and I held my fart all night, can I really not fart? ] 】

Director Jiang took a screenshot and threw the question to Gantian.

Director Jiang said: "This is the third question, after thinking about it, press the answering device, the time limit is two minutes, and the timer starts to ......."

"Smack!"

Gan Tian pressed the answering machine again in seconds.

Jiang Dao: "......"

Director Jiang put on a posture of resignation, and glanced at the number of online people in the live broadcast room, which has been rising and has risen to 6 million!

Roar~ It's worth it!

Director Jiang changed his state of heart congestion and laughed heartily.

Gan Tian glanced at the question in the screenshot and said, "It's very simple, alum has many uses, in addition to being a bulking agent, it is also a fixing agent. ”

Speaking of this, Gan Tian took a pen and paper.

Write the chemical formula of alum on a piece of paper.

"You see, alum, also known as potassium aluminum sulfate dodecahydrate, is dissolved in the trivalent aluminum ion AI3 ionized by water after water, and AI3 further undergoes hydrolysis reaction, that is, AI3++3H20= AI (OH)3 (colloid) +3H+, so that a positively charged aluminum hydroxide sol is formed.

Plant dyes like henna generally have a negative charge, and the positive and negative charges are firmly adsorbed together by the gravitational effect of coulomb, which reduces the solubility of the plant dye and reduces the impact of washing and fading, so it plays a role in fixing the color.

Alum water purification is also the same principle, the suspended particles in the water in nature generally have a negative charge, and the aluminum hydroxide particles dissolved in water have a positive charge, and the positive and negative charges can also be tightly adsorbed by the gravitational effect of Coulomb, and the accumulation and sinking occur, so that the impurities in the water sink together, making the turbid water clear. ”

After Gan Tian explained, Zhao Jiang shook his mobile phone: "The same principle, alum can not only be used as a fixing agent, but also as a water purifier. ”
