Dressed as a fake daughter, she just wants to farm

Chapter 176 Mars

It takes time to focus with the magnification environment, this thing is slow, Suning can only let Xia Niangzi lead everyone to endorse, and then stand in the shadows to endorse.

Everyone looked at Su Ning speechlessly, this is the devil, and extracurricular activities need to be endorsed?
Suning said who hasn't experienced the days of endorsement before running.

This is a simple little activity to memorize and endorse, which means nothing.

In the third grade, every student looked at Master Su under the sun in a daze, and went to endorse the book honestly.

There are several other masters waiting here, staring at them to endorse.

Yun Niang didn't have class today, so she didn't have to look at the students, so she walked up to Suning curiously and asked, "Ah Ning, what is this?"

Convex lenses have only been seen by third graders, and Yunniang really doesn't know.

Su Ning took out another one from his bosom, handed it to Yunniang, and said, "I call this a convex lens. It's thick in the middle and thin on both sides, and it has the effect of concentrating light."

"Focus on?" Miss Xia also came over. The third grade is still easy to manage, and the students are honest, so she is naturally relaxed.

Su Ning nodded: "Juguang, have you seen this bright spot? The temperature will gradually rise. After reaching a certain level, this piece of paper will be able to burn."

"Burn it?!" The two looked at Suning in shock.

how come?How to burn without fire?
Suning smiled mysteriously: "You will know later, but it's been a while."

Suning was slowly experimenting. The people next to him seemed to understand, and looked at Suning with half-belief.

The voice of the endorsement gradually became smaller and smaller.

Everyone's eyes gradually widened.

Because they saw a wisp of... smoke?

"Is that smoke?" Yun Niang rushed over, looking at the things under Suning in shock, "Can it really be burned?"

Everyone looked at Suning one after another, looking at the thing under Suning's hand, the smoke became more and more, and slowly changed, sporadic sparks appeared!

Mars!

"It's really burning?" Xia Zhixi stretched out her hand unconsciously, wanting to touch it, wanting to make sure it was real.

Xia Niangzi pulled Xia Zhixi over: "You are crazy, what should you do if you burn?"

Xia Zhixi came back to her senses abruptly, with an impressive expression on her face: "I'm stunned, but this sporadic thing can't burn me."

Suning took the convex lens away, revealing the sparks below, and said, "Let the students come over and take a look, don't let them touch it, don't get hurt."

Paper is flammable, otherwise it wouldn't be so easy to spark.

Sporadic sparks, slightly put on some flammable paper, the sparks are slowly spreading.

Not much, but enough to see.

This thing is literally on fire!
"It's amazing, Master, how did you do this?" The first grade children asked Su Master curiously.

Normally, Suning often takes them with them, and when talking with Suning, it doesn't seem like an adult is afraid of Suning's identity like an adult.

Suning rubbed the little girl's head, took out the mirror, and said, "Well, this convex lens is thicker in the middle, it can gather light, and it can gather the sun's rays together. It is also transparent, and the light gathers together. , Just like when you go out to bask in the sun, does it get hot when there is too much sun? Does your skin start to turn red?"

"Yeah, yeah, when the sun is hot, it's really uncomfortable, it's red, and it hurts." The little girl with that kind of skin is playing outside, and she is particularly prone to sunburn.

Su Ning said softly: "Yes, there are too many suns, and the skin will feel hot. This gathers all the light together, and it will be even hotter. Once it is hot, the paper will feel painful. Slowly the temperature Elevate it, and it will burn."

The children seemed to understand but nodded.

The adults are thoughtful, since this thing can do this, I don't know...

"If you're traveling, can you use this to light a fire?" Xia Niangzi asked.

She has a caravan, and the caravan usually carries fire pockets, but it is always better to have more.

If this thing can really be burned anytime and anywhere, it is a sharp weapon, and there should be many people who want it.

pity……

Su Ning shook his head: "Whether this thing can be burned depends on the thing, just like the one in my hand, it can only burn a small piece of paper, but if it is said to burn a fire, it will take much longer. It’s not as easy to use as Huozhezi.”

Xia Niangzi was a little disappointed, but thinking about it, this thing is not big after all, "If you change it, don't know if it's okay?"

Su Ning nodded: "Theoretically, it is possible. The more convex the convex lens is, that is, the thicker the middle part is, the smaller the focal length of the convex lens will be. The stronger its light-gathering effect will be, and the easier it will be."

It is not easy to make this thickness, mainly because the glass is too brittle and difficult to grind.

"Oh." Lady Xia understood.

What a little spark made the students' curiosity skyrocket.

They surrounded Little Martian one by one, wanting to move forward, but they dared not move forward. Their small bodies were stretched out, their small hands were stretched out, but their feet were far away.

"Master is so powerful, you made a fire out of thin air." A little girl said.

Su Ning was speechless when he heard the words: "It's not that I'm good, but it's far away. It's like making fire by drilling wood. This thing can also be practiced."

She didn't want to just solve one problem and then another.

The little girls don't care about Suning's explanation, today's scene directly brought the little girls' admiration for Suning to the peak.

Not only the little girls, but also the masters looked at Suning with admiration and respect!
As expected of a Xiangjun who was born with whimsical ideas, he is really amazing!

Suning rubbed his head, explained the principle over and over again, and finally gave up.

Anyway, it's a big deal for her to experiment a few times, and let others do it a few times, whether they believe it or not!
A lively extracurricular activity is over, but things are not over yet.

The little girls returned home, and as soon as the news spread, everyone knew that Suning was able to borrow fire out of thin air!
Light the fire with the power of the sun!
After finally convincing people that their houses won't shine, and now there's another one, it just makes people want to collapse!
"Why don't they believe it?" Suning couldn't help complaining to Su Mingzhi.

Su Mingzhi rubbed Suning's little head: "That's because my Ning'er is smart! There are so many wonderful ideas, they want to believe but they can't believe it!"

Even if he had seen and tried making fire out of thin air, he still couldn't believe it!

Suning is helpless, the nine-year compulsory education has a long way to go!
No one knows the simple physics knowledge?

Oh, it's not that no one knows, but few people can tell the principle, and many people have seen some examples of application.

Like, some little tricks...
