More than ten minutes had passed by the time Lin Yan's mouth went dry and he finished talking about all the things about paper and pen that he had extracted from the science and technology museum.
As soon as they finished speaking, they started asking questions, all kinds of questions.
Before the experiment, they should try their best to consider various possibilities and strive for success in a short time.
Mao Mu and Lin Yun still have problems when it comes to firing charcoal, involving the temperature of the kiln and the degree of sealing.
Finally, Lin Yan spread his hands and said: "The process and principle are roughly like this. As for the specific operations, we will wait until you encounter problems after you start. Although paper and pen are important, other things cannot be left behind, such as the transformation of textile machinery. And you After learning so much, I usually think about how to innovate and improve my daily life.”
In fact, Lin Yan also knew that they all had ideas, but the cold season had many restrictions and they could not conduct experiments.
When the hot season arrives and conditions permit, they will definitely bring many surprises.
She was still looking forward to it.
By the end of December, the temperature had risen significantly, the biting cold wind was gone, and the wind blowing in the face was warm and welcoming.
The ice and snow are gradually melting away, the tenacious grass and trees are sprouting buds, and the time has come for all things to revive.
People have been sleeping for three months, put on light clothes, get out of the house, and start the new year.
The beginning of the third year of the Solar Era was also the fourth year of Lin Yan's birth.
Since the house was built and people moved from the caves into the house, two cold seasons have passed and no one has died due to the cold.
Under Lin Yan's advocacy, people's living habits gradually changed, the feeding of babies became much more refined, and the child's survival rate improved a lot.
Although no detailed statistics have been made, every household knows that no one has died during the cold season in the past, especially the weak children who have the hardest time surviving.
More people are aware of the benefits brought by changing their living habits, realize that what Lin Yan said is true, and subconsciously follow her family's teachings.
As long as there is any movement in Lin Yan's family, it will quickly cause a stir. Needless to say, people will take it upon themselves to do it.
Unknowingly, Lin Yan has become a fashion leader in Sun City.
Therefore, when the cold season just passed, she took Shui Sheng and others to collect weeds and dead branches for experiments. People followed her before they knew what she wanted to do.
When Lin Yan saw more and more people carrying baskets, cutting grass and taking it home, she finally realized something was wrong. Not sure why, he asked: "Why are everyone here to cut the grass? Is it because the cold season has used up all the haystacks accumulated at home?"
"Probably not. I still have a lot at home. It's enough to feed the pikas and rabbits." Shui Sheng was also a little confused.
"Just ask someone. Just wait, I'll go." After Huang Ying finished speaking, she walked towards the woman closest to them.
She came back after a while, but the woman mowing the grass looked hesitant, wondering whether she should continue.
Hua Min hurriedly asked: "Have you made it clear?"
Huang Ying nodded, dumbfounded and said: "They are imitating us. In the past two days, everyone has been collecting weeds everywhere. Others imitated the same and thought it would be of great use, so they all came. I have just told her , we are preparing materials for testing, they have no other use, so she is still half-convinced."
"Can it still be like this?" Hua Min's eyes widened and he looked at the woman over there, "She doesn't seem to want to give up."
Maomu looked at it and said, "I'll go over and tell her to stop mowing the grass."
Lin Yan couldn't laugh or cry when she heard this answer. If there was any benefit, she would have encouraged everyone to do it together, so how could she act alone.
After Maomu's persuasion, the woman hesitated for a while and turned away.
Next, when they meet other people on the road, they will also persuade them not to follow them in vain.
The test materials haven't been prepared yet, and no one knows what the results will look like, so we can't use these many weeds for the time being. I don’t know which one works better. It’s too late to let others mow the grass together after the test results come out.
Five days later, everything was ready, and a group of people gathered together in Lin Yan's yard to prepare for the experiment.
They collected more than ten kinds of wild grasses, prepared many clay pots, assigned tasks to each person, and began to experiment with papermaking.
Lin Yan and Ye Cong were physically limited, so they did not take action.
The remaining nine people are each responsible for one or two kinds of weeds. Soak the chopped weeds in a clay pot, either with water or with plant ash, soil, charcoal powder, etc. added to the water.
They used everything they found that might be useful. Since they studied chemistry, they knew the secrets. Mixing various things together may cause various chemical reactions.
The papermaking experiment happened to be a testing process, and they were unwilling to let go of any possibility.
Everyone is serious and persistent, observing the changes in the clay pot every day.
After only one day, some clay pots smelled bad, while others had no change.
The smell was mixed, and the yard was filled with all kinds of strange smells from time to time.
Although Huahong knew they were going to do an experiment, he didn't expect it to be like this.
On the third day, the smell from a clay pot was so unbearable that she couldn't help but ask: "What are you doing? Why is it so smelly? Can you still eat later?"
Lin Yan also felt uncomfortable because she underestimated the consequences of the experiment. It would be a mistake to put it in her yard.
"Auntie, please bear with me for a while. We'll do it somewhere else in a few days."
Hua Hong: "This smell is really strong. Is it okay to smell it?"
"It should be fine." Lin Yan was not sure. She forgot to do the test protection, and she did not expect that such a situation would occur during the test.
"Everyone, stop for a moment and listen to me."
The people who were immersed in observing and recording all looked at Lin Yan. They all came to observe and record during class breaks.
"Lin Yan, tell me, we are listening." Mao Mu said loudly.
Others nodded.
Naturally, they could smell the smoky smell, but thinking about what they learned in chemistry class about the various changes caused by chemical changes, this should be normal, so they just endured it and passed it.
In order to make paper, they could still endure this little suffering.
Lin Yan asked everyone to go back to the house first. They couldn't stay in the yard anymore.
Shuisheng and the others did not leave immediately, but carefully made the records in their hands and sealed the clay pots before entering the house.
Seeing everyone looking at him, Lin Yan coughed and said sheepishly: "I forgot something. Chemical experiments are harmful, so we need to protect ourselves. Hong Ling, weave the finest linen thread into cloth and give it to Let’s make masks for everyone.”
"What does the mask look like?" Hong Ling asked.
Lin Yan drew a mask on the slate with a charcoal pencil and explained how to do it.
Hong Ling nodded after looking at it, "It doesn't look difficult to do. I'll do it when I get back in the evening."
"I'll help you." Huang Ying said to Hong Ling.
Others also said they would help make masks. This is something they all need to use, and everyone should do it together.
