Director Jiang was dumbfounded: "So fast? Answer in seconds?"
Director Jiang was heartbroken: What should I do if I am worried about money?
Director Jiang said depressedly: "You say."
Explanation of the sweet image: "The popping candy can beat in the mouth because the high-pressure carbon dioxide sealed in the popping candy is released as the syrup melts in the mouth."
Netizens in the live broadcast room pricked up their ears.
【What, hahaha, sealed carbon dioxide?】
[Could it be that carbon dioxide is the supreme being of the demon race, sealed in popping candy, and is just waiting for our mouths to help it break the seal? 】
【Shili Marshmallow is not talking nonsense, right?】
Gantian looked at the barrage and said: "To be more vivid, it can indeed be understood this way. This is due to the special production process of popping candy.
During the production process, popping candy will be sent to a high-pressure chamber that is dozens of times higher than the normal atmospheric pressure. The high-pressure chamber is filled with carbon dioxide. As the syrup is stirred and cooled, the high-pressure carbon dioxide will be trapped in the syrup and wait for cooling.
When the syrup is taken out from the high-pressure chamber, the cooled syrup will be broken by the high-pressure carbon dioxide inside and broken into pieces of irregular-shaped popping 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 candies and put them in our mouths. The carbon dioxide sealed in the popping candies vaporizes when heated and generates thrust, which makes them beat in the mouth. It's that simple.
Moms in the live broadcast room don’t need to worry. The carbon dioxide released by a pack of popping candy is not as much as that released by a bottle of Coke, so there is nothing to worry about.
If you don’t believe it, you can put the popping candy into water and see if it bubbles out in the water. These bubbles are carbon dioxide.”
So that’s how it turned out?
Netizens in the live broadcast room said: Thank you~I understand!
Gantian added: "Speaking of the clever use of carbon dioxide, the fried dough sticks everyone eats in the morning is also an example."
Director Jiang asked: "The deep-fried dough sticks also use carbon dioxide cleverly. How do you say that?"
Gantian 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 lose money. I feel sorry for Director Jiang across the screen. 】
Director Jiang gritted his teeth and said, "Okay, you tell me."
Gantian said: "Alum will undergo a chemical reaction at high temperatures and produce a large amount of carbon dioxide. Alum is added during the production process of fried dough sticks and fried in a pan. The carbon dioxide produced at high temperature will cause the fried dough sticks to expand rapidly in a short time, so
Alum can be used as a leavening agent.
You can observe when buying fried dough sticks. Those fried dough sticks that look a little puffy and have large holes must have added alum. The structure of fried dough sticks without alum is tighter. If you don’t want to eat alum, you can choose fried dough sticks with a tight structure.
, but in terms of taste, it doesn’t taste as good as the fried dough sticks with alum added, so you can’t have your cake and eat it too.”
Director Jiang touched his forehead: "So that's it."
Gantian stretched out her hand: "I have already answered two questions, one thousand yuan. It's troublesome. It's best to answer each question one at a time."
Director Jiang: "Why are you in a hurry? I won't refuse to give you anything."
Gantian: "Who knows?"
Director Jiang: “!!!!”
"How can I, a well-known director in the entertainment industry, still owe you this little money? Do you know how many male and female stars in the entertainment industry are vying to have a good relationship with me and want roles in my movies for no money?"
Gan Tian raised her eyebrows and told the truth: "So, I'm not in the entertainment industry. We are a one-time deal."
In the live broadcast room, netizens were laughing crazy when they saw Director Jiang's deflated appearance: [Hahaha, I'm going to die laughing, I've never seen Director Jiang so deflated, I'm going to repay you now, I'll let you lick a passerby~~~]
Director Jiang searched his pockets but couldn't find a dime. He angrily asked Gantian to add him on WeChat, and he forwarded it to her on WeChat.
Gan Tian took out her cell phone and exchanged WeChat messages with Director Jiang.
When adding WeChat, Director Jiang's eyes were sharp and he saw a familiar profile picture. When he took a closer look, Gantian had already taken back his phone.
Director Jiang rubbed his eyes. Is it an illusion?
How come he saw Gao Shen among Gan Tian’s WeChat friends?
In the live broadcast room, netizens were still asking various questions.
Director Jiang could only suppress the questions in his mind for the time being, watch the live broadcast and continue to select interactive questions.
[@十里marshmallow, when I was a kid, I watched my grandma dye her nails with impatiens, and she also used alum. It looked better than the ones I went to the nail salon to dye her nails. What’s the principle behind that?]
[The same world, the same grandmother, my childhood!]
[My grandma also did this. She pounded the henna, added alum, and then applied it on the nails. Wrap it with mulberry leaves overnight. When I woke up the next day, I opened the leaves and my fingernails were dyed beautifully. 】
[My grandma also did it to me, and she said I shouldn’t fart, otherwise I wouldn’t be popular anymore, which made me hold my fart in all night. Is it true that I can’t fart? 】
Director Jiang took a screenshot and asked Gan Tian this question.
Director Jiang said: "This is the third question. Once you have thought about it, press the answering machine. The time limit is two minutes. The timer starts..."
"Snapped!"
Gantian quickly pressed the answering machine again.
Director Jiang: "..."
Director Jiang pretended to accept his fate and glanced at the number of people online in the live broadcast room. They kept increasing and had already reached 6 million!
Hoho ~ it’s money well spent!
Director Jiang changed his state of mind and laughed heartily.
Gantian glanced at the question in the screenshot and said, "It's very simple. Alum has many uses. In addition to being a swelling agent, it is also a color-fixing agent."
Having said this, Gantian took a pen and paper.
Write the chemical formula for alum on a piece of paper.
"You see, alum, also known as potassium aluminum sulfate dodecahydrate, dissolves in water and ionizes the trivalent aluminum ion AI3. AI3 further undergoes a hydrolysis reaction, that is, AI3++3H2O= AI (OH)3 (colloid) + 3H+,
This forms a positively charged aluminum hydroxide sol.
Plant dyes such as henna generally have negative charges. The positive and negative charges are firmly adsorbed together through Coulomb attraction, thereby reducing the solubility of the plant dye and reducing the effect of water fading, so it plays a role in fixing the color.
The same principle applies to alum water purification. Suspended particles in natural water generally also have negative charges, while aluminum hydroxide colloidal particles dissolved in water by alum have positive charges. Positive and negative charges can also be tightly adsorbed through Coulomb attraction, resulting in aggregation.
"Sink, let the impurities in the water sink together, and make the turbid water clear."
After Gan Tian explained, she shook her phone at Director Jiang: "Same principle, alum can not only be used as a color-fixing agent, but also as a water purifier. One solution gets one free. Is this answer worth five hundred?"
