Seeing Huang Han tinkering with wires and those things that didn't know the purpose, Zhang Fangfen was shocked and said, "Don't mess around, it's terrible if you are electrified." ”

Huang Han said disapprerovingly: "Don't worry, I didn't connect the power supply at all, where is the electricity?"

"No, you are not allowed to play with this thing, I'm afraid! You haven't seen that 'one-armed' in Hedong, his arm was broken by electricity, and he was lucky to only burn his arm, otherwise the whole person would be burned. ”

"Mom, don't be afraid, I don't have the electricity at all, I'm pretending to be a fluorescent lamp for you to see. ”

Huang Han divided the parts by two and assembled the accessories on the wooden board that had been wrapped in white paper, and asked Cheng Wenge to tighten the screws with a screwdriver.

Zhang Fangfen took a look and said, "It's a little like a fluorescent lamp, but it's fundamentally different from others, can this thing be used?"

Obviously, Zhang Fangfen had seen the kind of fluorescent lamp with an enamel lampshade, and saw the difference between Huang Han's assembly of a simple fluorescent lamp.

Let her believe that this fluorescent lamp is basically the same as the finished fluorescent lamp when used, and it can only be convincing if it is connected to the power supply and lit.

But seeing Zhang Fangfen's awe-inspiring attitude towards electricity, it is definitely impossible to allow herself to climb onto the roof beam and start to connect the power supply to the fluorescent lamp, and she must be turned off.

Huang Han said: "Mom, Dad must know better than you, wait for him to come back and see if this thing can be used." ”

"Well, if it works, you can ask the electrician from the briquette factory to come to your house and help put it on. ”

Huang Han knew that there was no way to do it at this time, so he simply pulled Chengwenge to sit down, took out the application problem and asked Chengwenge to start doing it.

Seeing that Zhang Fangfen was still watching, Huang Han was about to play a game to catch the old man, and said with a smile:

"Mom, I did my homework with Cheng Wenge, he ate at my house at noon, you don't need to prepare anything, just eat whatever you have at home. ”

Hearing Huang Han say that Chengwen Pavilion was staying at home for dinner, Zhang Fangfen was very happy and said, "Then how can it be done? ”

Cheng Wenge realized that Zhang Fangfen was going to go out to buy vegetables, and hurriedly said: "I, I, I didn't ......"

Huang Han saw that he could take Zhang Fangfen away with a little trick, he smiled secretly in his heart, pretending to be serious and said: "Chengwen Pavilion, don't speak, you have to do your homework seriously." ”

Chengwenge saw Huang Han making his eyes, and he didn't know why, "You, you ......"

Seeing Zhang Fangfen going out with a vegetable basket, Huang Han said: "Hurry up and start work." ”

"Do what?"

"Install fluorescent lamps!Let's go, follow me to borrow a ladder!"

"Are you really going to install your own fluorescent lamp?"

"Of course it's true!"

"You, will you?"

"Don't be verbose, we'll see the results later, shut up and obey orders now. ”

"Oh!"

Huang Han led the bitter-faced Chengwen Pavilion to the neighbor Gu's house to borrow a bamboo ladder.

Under Huang Han's command, Chengwen Pavilion put a bamboo ladder on the second beam, and Huang Han was about to climb the ladder.

Cheng Wenge suddenly said: "Huang Han, I'm also afraid, don't you touch those wires, okay?

"Don't talk nonsense, the switch is not turned on, there is no electricity there at all, where is the electricity?

Be obedient, and it will be over in ten minutes. You have to help me hold the ladder, and I must hold it steady, or I may break my leg. ”

"Oh, slow down, be careful!" Cheng Wenge was very nervous, his eyes staring at Huang Han for fear that he would fall.

Being small and light is also advantageous, and it is very flexible to climb the bamboo ladder to wiring.

Zhang Fangfen went out for half an hour, and when she came back, she bought a chicken, two large crucian carp, and three or four vegetables, and was shocked as soon as she entered the door.

Huang Han's house is an old house, the windows are small, and the light in the house is poor, Huang Han installed the fluorescent lamp and turned it on directly to prepare to surprise Zhang Fangfen.

In fact, before Zhang Fangfen came back, the lit fluorescent lamp had already surprised Cheng Wenge.

"Huang Han, you are too godly, how can you do this? No, you lied to me, you just said that there was no electricity at all, why is the fluorescent lamp on now?"

"I didn't lie to you, I didn't just ask you to carry a ladder to accompany me to the meter. ”

"What do you mean!"

"Didn't you see me close that white switch?"

"See!"

"Pulling down the power switch means that the power is off, and closing the power switch is the power connection. ”

"Oh! I think I saw my dad do the same. Why do you know how to connect electricity? You can make your own fluorescent lamps, even my dad can't. ”

"Learning, you will only cry when you are born, and after learning, you will master knowledge. But I want to warn you! You are not allowed to touch anything related to electricity until you have mastered the knowledge of electricity. ”

"This still needs you to say, you let me touch me and I don't dare, my father said that someone in the intermodal company has been electrocuted before. Died an ugly death. ”

Following Huang Han's help, seeing Huang Han piecing together a few messy things into a lighted fluorescent lamp, Chengwenge was full of interest, and concentrated on helping Huang Han tighten the screws to assemble the second lamp.

At this moment, Zhang Fangfen, who was carrying a vegetable basket, entered the door, her face was full of disbelief, and she pointed to the fluorescent lamp and asked Huang Handao: "Is this really what you installed it?

Huang Han, who had already taken countermeasures, opened the junior high school physics book and pointed to the text that wrote the principle of electric light:

"Mom, the reason why we go to school is to read and learn knowledge. Why do you want to learn knowledge? To apply it, of course. Look here, how to wire the lights, it's clearly written in the book. ”

Zhang Fangfen is literate, she read the text carefully, and only felt that it was like reading a book from heaven, although she knew that the content was related to electricity, but she didn't know why.

"You can read everything written in the book?"

Of course, why does everyone say that there are thousands of grains in the book, and there is a golden house in the book, and the book is to teach people to learn knowledge. ”

"You can install fluorescent lamps when you read a book?"

"Yes! Installing fluorescent lamps is not to make two bombs and one star, as long as you are not stupid and read the book, you will naturally understand. ”

Zhang Fangfen didn't believe it, but the lit fluorescent lamp was in front of her, and she couldn't believe it, the expression on her face was extremely complicated, and then the fifth aunt walked in.

She just saw the bright hall in the third brother's house in front of her, and deliberately ran to take a look, "Wow, the fluorescent lamp has been installed so quickly! Is this the electrician master? What a young man!"

Of course, the fifth aunt didn't know that Huang Han installed the fluorescent lamp by himself, and when she saw the tall Chengwen Pavilion, she thought he was an electrician.

Cheng Wenge was a little embarrassed, he was an honest man, afraid that others would misunderstand, and said: "Auntie, I am not an electrician master, my name is Cheng Wenge, I am Huang Han's classmate, I just help tighten the screws and escalators today, and the fluorescent lamp is installed by Huang Han."

"Ah? Huang Han installed the fluorescent lamp by himself? obediently bang, no life, Daowu, Daowu, come quickly!"

Huang Daowu's voice came, "What kind of soul are you shouting? When people heard it, they thought something was wrong!"

"See what this is?"

"Nonsense, I don't recognize the fluorescent lamp? Hey, this fluorescent lamp looks a little weird!"

"This is Huang Han's own pretending!"

"What? Huang Han pretended? You're not telling a joke, are you?"

"I just saw him and this classmate carrying a ladder to the main hall, and now I know that they are going to pull the electric switch to install fluorescent lamps. ”

"Impossible, right? Huang Han, you really installed this fluorescent lamp!"
