Chapter 128 Protecting the Curiosity of My Brothers

This time, Shen Zhiqiu was very careful in making up this lie. At least Mr. Shen, Old Man Shen, and even Old Lady Hua believed it.

After all, they didn't know anything about time travel or anything like that. They could only sigh that this kid was really smart, just like those child prodigies that everyone talked about.

The main reason was that the lies Shen Zhiqiu made up this time were similar to what Mr. Shen thought in his heart, that this kid was just too smart and loved to tinker with everything he saw.

When he was young, he often went out to do carpentry work. There was a young master from a wealthy family who was particularly curious about being a carpenter. When they were working,

The young master was watching from the side, and he learned it right away, and his work was much better than those of the mediocre ones.

The experienced carpenter he followed at the time also privately sighed that this young master was really talented.

This little great-granddaughter is probably the gifted little prodigy that the old master mentioned. It's a pity that she is a girl, otherwise the Shen family would have really risen.

Thinking of this, Master Shen once again told him seriously:

"You must tell the villagers about this later. You can't tell anyone that Yoyo is so good at making things. You are right. If people find out, we peasants won't be able to protect our child."

When Shen Zhiqiu heard this tone, he knew that the old man believed it. No wonder the old saying goes that old people become wise. If there is something wrong in the future, he really needs to think about how to explain it.

But as for what her daughter will come up with in the future, she is not afraid of anyone thinking too much about it. Children are smart and they just like these things.

This was a good excuse for him to give his granddaughter.

"Okay, Grandpa, I understand. I will definitely tell everyone. Don't tell anyone else."

Here, Shen Zhiqiu was trying to fool Shen Youyou, but Shen Youyou knew nothing about it and continued making her pine-scented soap.

The essential ingredients for making soap are animal or vegetable fats, oil and water.

Although there is no soda ash, wood ash can be used instead. This was made many times when rubber was made before.

This time, the lye water was made without any accidents.

The production method is simple, and the ratio of wood ash to water is about 3:7. This can dissolve the alkaline components in the wood ash into water to form lye.

Put the mixed wood ash and water into a container and heat it on the fire to boil.

This step helps speed up the dissolution of the alkaline components in the wood ash into the water.

After boiling, the mixture is allowed to cool naturally and then filtered to remove insoluble matter, leaving behind a clear lye solution.

All that remains is the making of soap.

Shen Youyou first melted the solidified palm oil in a ceramic pot, then added alkaline water into the pot, stirring constantly while heating to ensure that the reactants were fully mixed.

During the heating process, the oil and alkali undergo saponification reaction to produce sodium higher fatty acids, which is the main ingredient of soap.

This process takes a long time, so she needs to stir constantly to prevent the reactants from sticking or burning.

"Sister, what are you doing?"

Just when Shen Youyou was concentrating, Shen Luming came over quietly and scared Shen Youyou.

Seeing that his sister was scared, Shen Luming quickly smiled at her ingratiatingly. Shen Yuanbao, who was following behind him, also squatted beside the small stove curiously, his big eyes sparkling.

Shen Youyou didn't stop stirring the food in her hands. She whispered to her two brothers, "I'm making some fragrant soap. We're running out of it soon."

The eyes of Shen Luming and Shen Yuanbao, the two little guys, became brighter. They didn't expect that their elder sister could also make soap.

The two said in unison: "Sister, we can also help."

Shen Youyou found it funny, but it was necessary to cultivate her younger brothers' hands-on ability, and she was also very happy that her two younger brothers liked these things. After all, China's strength was inseparable from the exploration and research of generations.

"Okay, my arms are sore, Yuanbao, stir it for me. Don't stop stirring, and don't stir too hard, or it will spill."

Shen Yuanbao was very happy and quickly accepted Shen Youyou's work and started stirring just like her.

Shen Luming was extremely envious, and looked at Shen Youyou with his big, bright black eyes full of anticipation.

Shen Youyou first reminded Shen Yuanbao to be careful not to burn himself, then turned to look at Shen Luming's expectant eyes:

"Lulu, you are too young to stir, but I can let you do an equally important task, okay?"

After hearing his sister talk about the more important task, Shen Luming nodded his little head like a chick pecking at rice.

Shen Youyou took the small bamboo tube filled with rosin and handed it to Shen Luming:

"This contains the rosin that my sister extracted. When Yuanbao is stirring, can you pour half of the rosin in this small bamboo tube into it?"

Shen Luming was stunned, thinking it was an important task. It turned out to be just adding some rosin as his sister mentioned. Such a simple task, Shen Nannan could probably do it too.

Seeing her brother's disappointed look, Shen Youyou quickly said, "Lulu, don't underestimate this task. You should know that the pancreas made in this way will not be fragrant.

Only by adding the rosin in the bamboo tube can it become a fragrant soap. And if you add too much, it will be too fragrant, and if you add too little, it will not be fragrant enough. This requires a lot of technical content. "

Shen Youyou's nonsense obviously aroused Shen Luming's interest. In fact, what's the big deal if he added more or less rosin? He wasn't going to sell it, so he didn't have high requirements for his own use.

But we must never discourage my brother's enthusiasm, and we must promote the work he does to a crucial position.

Children's curiosity about new things should be cultivated from an early age, of course this does not include those things that are reckless.

For example: Yu wants to touch the tiger's butt...

Shen Luming took the bamboo tube from Shen Youyou, opened it and smelled it: "It smells so good, sister. It smells better than soap."

Shen Youyou nodded: "Well, this is the concentrated essence, of course it smells good."

Although the two younger brothers didn't understand what Shen Youyou said, it didn't stop them from being curious. Shen Luming liked the smell very much and kept sniffing it.

Shen Yuanbao was anxious, but he did not stop stirring: "Lulu, let your brother smell it."

Shen Luming took the small bamboo tube and carefully let Shen Yuanbao smell it.

Shen Yuanbao wanted to smell more as if he hadn't smelled enough, so Shen Youyou reminded them:

"You two are almost there, don't let the fragrance overwhelm you. When we make the scented soap, it will all have this scent, and you can use it to wash and smell the same."

Seeing that it was almost done, she reminded Shen Luming to pour in the rosin and asked Shen Yuanbao to continue stirring.

After waiting for a while and mixing everything evenly, pine oil was added. The two little guys were curious: "What is this, sister?"

"This is pine oil, which has the function of disinfection, sterilization, and moisturizing."

I thought my brother might not understand, so I said in plain language:

"Why do we have to wash our hands after eating? Because when we touch other things with our hands, many invisible bugs will stick to them. This thing in my hand is to kill those bugs.

Moisturizing means that our hands are prone to dryness and cracking in winter, and adding this can replenish moisture and oil to our hands, making them less dry. "

Shen Youyou felt that explaining everything to her younger brothers was more tiring than making soap.

As Yuanbao stirred, the saponification reaction in the earthenware jar became more and more obvious.

When the saponification reaction was completed, Shen Youyou added salt into the pot, and Shen Yuanbao continued to stir to fully dissolve the salt.

This step is called salting out, and it helps to cause the soap base to coagulate and form the basic shape of the soap.
