Chapter 958 This mirror is good
The principle of crystallization is that a supersaturated solution of sodium acetate releases heat when it crystallizes.
This crystal is called sodium acetate trihydrate, also known as "hot ice".
Because the crystallization process is reversible, once the heat used to form the crystals dissipates, the crystals can be heated again and can be reused.
Last night, Shen Qingqian improved the common bye-bye heat so that it could heat up quickly again after the heat dissipation was completed, thereby forming crystals again and continuing to dissipate heat.
It sounds complicated, but it is not difficult for Shen Qingqian. As long as there are enough materials, it doesn't matter how much she makes.
Sheng Ze, Yuan Lai and Jun Yichen did not come for breakfast today. When they came, the women of the Shen family were all in the house.
After greeting everyone, Sheng Ze and the others looked at them curiously.
"What are you doing?" Yuan Lai came forward and saw the women of the Shen family sewing something.
Shen Qingqian smiled at Sheng Ze, then lowered her head to stuff something into each of the bags, and casually replied to Yuan Lai's question, "For the winter."
Liang picked up the finished product and handed it over. "Here, take a look at it too. With this stuff this winter, our hands and feet will definitely not get cold."
She even thought, if she could sew a larger leather bag out of animal skin, could she tie it over her inner clothes and then put on her coat? Wouldn't that keep her from getting cold?
Yuan Lai fiddled with it curiously, and after a moment his eyes lit up, "Wow, this thing is pretty good!"
"Mr. Yuan, being able to generate heat is nothing. The key is that it can still generate heat after it has cooled down!" Lin added with a smile.
Shen Qingqian used the excuse of moving materials from the sugar factory's cellar, and the Shen family didn't suspect anything. They just did whatever she said. Until now, no one knows what they put in the skin bag.
Yuan Lai became interested, "It's so magical, I must take a good look at it."
He took the things into the house, intending to study them carefully.
Sheng Ze was thinking about what he remembered last night, so he went to Shen Qingqian and whispered, "Sixth sister, I have something to tell you."
Shen Qingqian looked up when she heard that, and saw a hint of distress in his eyes. Her original refusal turned into, "Okay, go to the next room and wait for me."
After she finished speaking, she turned her head and said to Shen Qingman, "Second sister, these two things are very important. Don't forget to put them in these leather bags."
What she is doing is stuffing condensation nuclei and the things she has improved into the skin bag. Without the condensation nuclei, it will not be able to heat up. Isn't it very important?
"Okay, just rest assured that I will do my job. Go quickly." Shen Qingman covered his mouth and smiled, then glanced towards Sheng Ze.
Sixth sister certainly doesn’t know that her behavior towards Sheng Ze is different from that towards other opposite sexes.
She didn't know why before, but now she completely understands. Being young is just the best!
Shen Qingman may have forgotten that she is only a few years older than Shen Qingqian.
Shen Qingqian finished explaining things, but found that Sheng Ze and Jun Yichen were both there.
She was a little surprised, "Do you two have something important to tell me?"
"Sixth Miss." Jun Yichen stood up and greeted her.
Shen Qingqian quickly returned the greeting, "Mr. Jun, there's no need to be so kind. It's better to be more relaxed."
This Jun Yichen is really something. He used to be cold, but now he is gradually changing. I wonder what kind of person he is.
"Qianqian, I want to ask you to help me look at something. I wonder if you have seen this thing before." Sheng Ze took out a mirror from his arms and handed it to her with expectation in his eyes.
Shen Qingqian took it and looked at it, "This mirror looks pretty good!"
"What's wrong?" Sheng Ze was attracted by her exclamation and immediately leaned over, his head almost touching Shen Qingqian's.
