After writing the couplet, Liu Quan quickly served fragrant tea so that her husband could take a break.
However!
Qi Yu had just taken the teacup when a strong pungent smell wafted over his nose.
Well……
Is there something wrong with the tea?
Liu Quan rolled her eyes at him, seemingly saying: You are Qi Dalang, not Wu Dalang, why are you so suspicious?
Well, since it's not the tea that's the problem, there must be another 'source of the odor'.
Where did this pungent smell come from?
Qi Yu put down the tea cup and murmured: "This smell is very unique, it feels like deja vu..."
Deja vu?
real or fake?
Liu Quan sniffed it carefully, but shook his head and said: "This is the first time I smell this strange smell. I have never smelled it before."
Yin Tao also touched her Qiong nose and said the same: "I haven't either."
From this point of view, only Qi Yu can distinguish this smell, but the two girls cannot.
So, the two of them cast inquiring glances at him.
Qi Yu squinted his eyes and tasted it for a while, then suddenly smiled and said: "Hahaha, I know what that is."
The two women were startled and asked in unison: "Oh? What is it?"
However, Qi Yu gave it up and said with a smile: "The thing that stinks like this is very precious, almost as valuable as gold. As for what it is, you will know later when you take a look."
However, not everyone is equally curious.
Compared with Yin Tao who was eager to find out what happened, Liu Quan seemed a little less interested.
She felt that it was more practical to stay at home and help her mother-in-law wash vegetables than to watch those indifferent weird things.
Oh well!
In this way, Qi Yu walked out of the house with only Yin Tao, and then followed the pungent smell and leaned closer.
It turned out that the smell was actually coming from a courtyard not far away.
Yin Tao looked surprised and said: "It's really strange. Why is there such a strange smell in my home?"
Not only her, Qi Yu was also very surprised by this.
He smacked his lips and guessed: "Could it be that one of your students came to your house and started an experiment?"
"How is that possible? The entire college is on holiday, so where are the students to make up the classes?"
"That's right..."
There is no point in guessing. Just go and see what it is like.
good!
Soon, they arrived at the door of Yin Meiren's house.
When he looked up, he saw that the door was ajar.
"It's really strange. I locked it when I went out. How come it's unlocked now?"
"If you can open the lock, it proves that the person entering the door holds the key. From this, it can be seen that the person must not be an outsider."
Qi Yu really guessed this.
The one doing the experiment was indeed none other than his precious son Qi Xiao.
No wonder I didn't see anyone else after lunch.
In front of me, I saw that the little guy was sweating profusely and was very busy pulling the bellows to add firewood to the pot.
However, what was cooked in the pot was not edible food, but some dark goo.
Those pungent odors are emanating from these black things.
Suddenly, Qi Xiao stopped the bellows in his hand and hurriedly poured the half dustpan of sulfur he had prepared in advance into the pot. After that, stir quickly without stopping to mix the contents of the pot evenly.
This is……
Yin Tao just thought about it briefly and suddenly realized: He was doing an experiment on rubber vulcanization!
Yeah?
Yes! This is truly a rubber experiment!
It turned out that after Qi Yu promulgated the decree on rubber collection, Qi Xiao, who was more powerful than Newton, couldn't help but feel itchy.
Is the sap produced by those trees really as magical as Dad described?
In fact, there was something wrong with what he said since then. Newton studied physics, when had he ever participated in advanced chemistry?
He felt that Gui Lao, whom even his father admired so much, was definitely not an ordinary person. It was really appropriate to compare him to him.
Let’s go back to rubber.
In order to prove the correctness of this theory, Xiao Qixiao secretly collected a bucket of rubber juice for exploratory experiments.
Practice is the only criterion for testing truth!
Yes, daddy did say that.
If you can only talk and talk on paper, what's the difference between that and Ma Su who talks a lot?
So, you have to really do it!
The starting point is good, but the little guy is afraid that the experiment will fail and lose face.
Afterwards, he thought about it and figured out how to cook it secretly while Yin Tao was not at home. Even if it failed, his aunt wouldn't be able to see it~~
But who would have known that the smell of cooking this thing is extremely strong. You can smell it from a distance of two hundred feet, and you can't cover it up even if you want to.
The result now is that this move not only attracted the onlookers of my aunt, but also attracted the intimidating father.
It’s really not as good as God’s calculation~~
Seeing the two adults laughing non-stop, Xiao Qi Xiao was so embarrassed that his face turned red and his neck was thick, and he wished he could find a crack in the ground to crawl in.
After he finished laughing, Qi Yu hurriedly put on a stern tone and pointed him out: "As I know, rubber vulcanization is a cross-linking reaction. There is a very strict proportion of sulfur in it. It doesn't mean how much sulfur you want to add. You can add as much as you like.”
After saying that, he took out the pen he carried with him and started scratching on the paper.
When explaining, he deliberately went from simple to complex, step by step, and tried to make it as easy to understand as possible. If something is obscure, explain it again and again to ensure full understanding.
Suddenly!
Qi Yu was surprised to find that his son's understanding speed exceeded that of Yin Tao, who was extremely intelligent. It can also be seen that this little guy does have a talent for science that is beyond ordinary people.
This phenomenon also strengthened Qi Yu's idea of teaching his son in accordance with his aptitude.
Originally, he had thought of asking Qi Xiao to take the imperial examination to show off his identity as a boy student later in the year, but now it seems that it is completely unnecessary.
Since he is really good at science, there is really no need to take the civil examination route.
Let’s talk about the present first.
The three of them struck while the iron was hot and began to correct various errors in the experiment just now.
The hard work paid off, and the sky turned dark, so they figured out the basic principles of rubber vulcanization.
With this smooth start, things will be much easier to handle later on.
As the old saying goes, everything is difficult at the beginning?
It's true if you think about it.
After a while, Qi Yu picked up a tofu-shaped rubber product and said with a smile: "If some appropriate amount of graphite is added to it, its physical properties will be even better."
Yin Tao smiled and said: "It is very smooth to be able to achieve this step in a hurry. As for the subsequent improvement, a lot of experiments are needed to support it, so there is no rush."
Well, that’s true!
Qi Yu laughed, turned around and touched his son's head and said, "The research on rubber is over for now. Next, let's go home and have dinner!"
Rome wasn't built in a day, it takes a long time.
However, Qi Xiao's excitement has not completely faded away, and he still wants to keep up his efforts.
However, his father spoke and he had to put it down temporarily.
Qi Yu was very happy and kept mumbling: Today's dinner must include a glass of wine to celebrate the first shot of rubber development.
Haha, this year has been so meaningful that I can’t even think about being happy.
However, some people are happy and some are worried.
Take Huang Fei for example, he feels a little nervous now.
As for the method of tooth removal, we will analyze it next time.
