"Why did you come back so late at noon today?"

Zhang Fang looked at his son who was sweating profusely as he walked in the door, and asked Bai Qing with a somewhat puzzled tone on his face.

On weekdays, because she is busy selling roasted gluten, she has to come back late even at noon, but today, seeing that she has been back for most of the day, even the accounts have been sorted out, Bai Qing

Cai Cai appeared belatedly at the door, and Zhang Fang couldn't help but feel confused.

During this period of time, this kid was always mysterious and a little restless. This was the most rebellious age, so don’t be a bad example. When she thought of the little ruffians she saw on the road who were not doing their jobs properly, she

I couldn't help but feel a little worried in my heart.

My son was useless before, but now I finally have some hope for him. Don't let him fall down anymore.

Don't expect him to become a talented person, at least he should be an upright person.

"I went out to buy something, so I came back late." Bai Qing waved the thing in his hand toward Zhang Fang, and before Zhang Fang could see what it was, he said to Zhang Fang eagerly: "

Mom, hurry up and eat, I’m starving to death!”

As he spoke, he hurriedly ran to the sink to wash his hands, temporarily escaping from Zhang Fang's sight.

"You just go wild and don't even know how to call me or your dad!"

Hearing that Bai Qing was not fooling around outside, the big stone in Zhang Fang's heart finally fell. After hearing Bai Qing's words, she temporarily put aside those previous thoughts, and then said something as usual

Muttering unreasonably, he walked into the room and sat at the dining table.

Bai Yuejin was already half full, and Zhang Fang hadn't eaten since he hadn't seen his son come back.

Not long after, Bai Qing trotted in, sat down, picked up chopsticks and steamed buns, and started eating like a storm.

This young body was already growing, and after another morning of study, it was already hungry and its back was pressed against its belly. Now he was frantically absorbing energy from food.

"Slow down, don't choke, why are you eating so fast?"

Seeing Bai Qing's appearance, Zhang Fang frowned and continued to chatter. For Bai Qing, this was a common occurrence. Even when he was in his thirties in his previous life, Zhang Fang still looked like this.

Feeling that he was no longer so hungry, Bai Qing gradually slowed down. In just ten minutes, he finished his lunch, wiped his mouth, washed his dishes and chopsticks, and returned to himself.

s room.

After closing the door, he placed the things he had just bought from the market in his schoolbag on the table.

Ten small ball bearings, a few thick screws, and two sticks of all-purpose glue.

That's right, he just wanted to use these things in front of him to make a simple fidget spinner sample.

Bai Qing is not an outstanding craftsman after all. In his previous life, he was just out of interest and had seen several simple methods of making fidget spinners on the Internet. After having an idea of ​​this gadget last night, he

It took almost a whole morning to recall and design, then purchased these parts and started manufacturing and assembling them.

In fact, for a fidget spinner, its most core component is the ball bearing, and the others are just different in appearance.

He first planned to make the simplest and relatively stable one, a three-blade top.

First, I took a bearing, and then compared the points drawn on the paper to determine the locations where the other bearings were bonded, and marked them accordingly. Then I picked up the small paper and marked the appearance of the bearing.

The parts were rubbed vigorously until the originally smooth outer wall was covered with rough scratches.

This is also to increase the adhesion of the universal glue. After all, it has to stick. However, if the adhesion of the all-metal bearing is insufficient, it will directly lead to the failure of the gyro production.

Especially this is for demonstration. If one of them falls off when showing it to Fang Yun, then he will be a Spartan.

After all three marked positions were polished, Bai Qing also selected a position for polishing on the other three bearings.

Bai Qing spent most of noon rubbing and rubbing, and the table was covered with many shiny iron filings.

After it was almost completed, Bai Qing touched the polished areas. After feeling the rough touch on them, he nodded with satisfaction, then took the all-purpose glue, applied glue to the polished areas, and then glued the other areas.

The three bearings fit tightly on top.

Afraid of insufficient adhesion, Bai Qing deliberately applied a thick layer, and then used some heavy objects to firmly resist the sticky areas.

The next thing Bai Qing has to do is wait.

With the universal glue these days, it takes a lot of time to completely bond.

At this time, Bai Qing missed the days of hot melt glue. Unfortunately, in a small city like Tobu in 1998, it was impossible to buy this stuff.

Simply waiting is boring, so Bai Qing put this matter aside and went to bed directly to sleep.

Until noon of the next day, Bai Qing moved away the heavy object and carefully took the semi-finished product in his hand. He gently tried the sticky area and found that the strength was okay, so he took out the early

The prepared colored threads were slowly wrapped around the sticky parts. After wrapping a thick layer, he re-coated the colored threads with all-purpose glue.

It is said that this kind of operation is to increase the adhesive strength of the glue, and Bai Qing has never done it by himself before. After all, it only cost a few dollars to buy a fidget spinner in his previous life. Who would do it by himself? Since he

He vaguely remembered that this was what the tutorial said, so he simply followed it.

However, for the sake of beauty, he used three different colored threads: red, green and yellow.

Now that the glue has been applied, it naturally has to wait for a while to dry, so after Bai Qing carefully checked it, he put it there again.

Another day later, when Bai Qing came over to take a look, the all-purpose glue on the colored thread had dried completely. He still carefully tested the strength. After he thought it was pretty good, he put the thick screw through the middle of the bearing.

hole, then screw on the nut, pinch the upper and lower ends of the nut with your index finger and thumb, pin one of the bearing blades with your middle finger, and then gently push it.

brush

Accompanied by a crisp friction sound, the bearing, with its three blades, began to rotate rapidly, and soon it became a mass of shadows. Only the bursts of brushing sounds could be heard, making people unconsciously addicted to it.
