Su He, who succeeded in the experiment, did not choose to continue.
There is no need, and there are relatively few drugs in the laboratory.
There are very few experiments in chemistry classes in this era.
In many places, experiments are not even done.
Bishui City No. 4 Middle School has good student performance and a good enrollment rate every year.
No. 4 Middle School still pays more attention to it, but even so, the number of experiments per semester is only a handful.
Su He saw the pain in the chemistry teacher's body and immediately said to the chemistry teacher: "I don't know how much these things cost. I'll give the teacher three yuan and buy them back through the school's channels."
There are many things that are difficult to buy personally, but the school’s channels are much easier to use.
The most difficult part of a small electric fan is the battery. In fact, Su He has already made all other parts, including the motor.
He assembled all these things, made something similar to a bracket, and installed the fan blades on it.
Su He found another place to charge the lead-acid battery.
Whether it works well or not depends on the situation at night.
He turned around and tried again, adding a piece of plastic to the front of the chef's hat, and then planned to sew it up with needle and thread.
But obviously, Su He overestimated his sewing level.
Looking at the crooked and unbalanced stitches, I suddenly blushed.
"Let me do it."
Su He looked up, and at some point, Ye Qianqian came here.
He just came to this small forest to try it out during his self-study class.
Unexpectedly, Ye Qianqian would see her sewing a hat, and it was a failed attempt.
His old face turned red, but Su He still handed it over: "Just sew this thing on the front of the hat."
Ye Qianqian took it and removed the stitches that Su He had sewn before with just a few clicks.
Then start sewing.
Otherwise, how can we say that professional things should be left to professionals?
Look at Ye Qianqian, her craftsmanship is much smoother.
In just a few moments, Ye Qianqian had the thing sewn up.
"Let's see how it goes. If it doesn't work, I'll change it again. But why do you want to install this thing?"
Ye Qianqian was really curious: "Why didn't you let us do it before?"
Su He said: "It's too hot in the summer when I'm wearing a hat. I'm thinking of making a few small electric fans that can be placed on the hat. The wind blows and people stay cool. In addition, the wind blows, The sweat will be easily evaporated and will not fall off. One is that it will not wet the clothes, and the other is that if the sweat falls into the ingredients, it will be even more embarrassing."
People this year probably don't have this awareness.
But Su He had to take this into consideration if he planned to start a catering business.
Always think before the guests, this is also a quality that the catering industry, or the service industry, must possess.
After finishing, the two were ready to go back to the classroom.
After one more class, it's time to get out of school.
But at this moment, the voices of several people came.
"Look, it's these two people."
"You dare to talk about a partner in school, isn't it too bold?"
"I don't know what I'm doing in the woods. I won't do anything shameful, right?"
Su He frowned, and Ye Qianqian's face turned red.
His eyes were already red.
Su He thought she would run away. Ye Qianqian, whom he had met before, was a relatively shy person.
But surprisingly, Ye Qianqian did not leave. Instead, she went over and started arguing with those people.
Su He was helpless. No matter how much you reasoned about this kind of thing, people just didn't believe it.
No, there was already a quarrel.
Su He stepped forward and said to Ye Qianqian: "Forget it, what are you going to explain to a few people who are full and have nothing to do? Those who are pure will become clear themselves, and those who are turbid will become turbid."
After saying that, Su He still said to the women: "It's better not to believe or spread some unfounded rumors. If I hear some rumors that I shouldn't have, don't appear in the same place with boys. Otherwise, you should not appear in the same place with boys." Rumors about you will soon spread to all the schools in Bishui City."
Spreading rumors is actually very simple and the cost is very small.
If you are willing to spend a little money, it will spread very quickly.
With that said, Su He asked Ye Qianqian to leave.
Ye Qianqian originally had the energy to argue with those girls, but when she turned around, her eyes were red and she shed tears.
Su He was helpless: "You didn't shed tears before, why are you crying now?"
Ye Qianqian wiped away her tears and said, "Those people before were all enemies. Naturally, I can't shed tears in front of my enemies. Aren't there no enemies now?"
Well, Su He didn't know what to say.
But he had also seen this saying in his previous life about not shedding tears in front of others.
Just because you have no one to rely on, you have to swallow all the pain yourself.
They went back to school separately. Su He didn't take this matter to heart.
After school in the afternoon, I went back and made dinner.
Su He saw that the time was almost up and waited at home for He Bureau to pick him up.
Where Chief Gongyang lives, Su He, an ordinary person, shouldn't even think about going in directly.
No matter which country you are in, the protection of leaders is very strict.
Ye Chengbo was cleaning tools over there, and he was very obedient in this regard.
Su He nodded at this, took out the chef's hat he made during the day, and said to Ye Chengbo: "Try it and see if this hat works well."
Ye Chengbo was a little strange, seeing that there was an extra protruding part on the brim of the hat.
There is a shelf above, and a fan blade is placed on the shelf.
There is a wire connected to the back, which is always connected to a dark thing below.
Su He didn't pay much attention to the color, and didn't dare to make it too conspicuous.
It's better to keep this thing low-key.
Although in terms of practicality, it is already very low-key.
Ye Chengbo asked: "Is this an electric fan? Is this what you made?"
Su He glanced at Ye Chengbo angrily: "Isn't it because I see you getting so hot under the big sun every day? This hat brim can protect you from the sun, and this small fan can give you some air to cool you down. I I put down the big electric fan used at home and did it for you first."
With that said, Su He demonstrated how to put it on and asked Ye Chengbo to put it on.
"This thing is actually very simple. After you put it on, the battery here is a little heavy. You can tie it around your waist and walk around at will, but it may be tiring. There is no way, lead-acid batteries are not good at all. Okay, there's no way to control the weight. If you think it's too heavy, you can put it aside. Anyway, the length of the wire is a little longer, so you can extend it a little. Anyway, you don't have to run around when making egg pancakes, just put it aside. That’s it. Well, it’s that switch, you try it.”
