House Dad’s Literary Life

"This is called Nicholas Eggs!" Lu Benjie heard a whisper, and then turned his head and looked at her. He said, "Are we not able to rotate the egg up? But this can help us. Let the eggs stand up and rotate!"

I haven’t got rid of the guilty feelings just now. I accidentally flew and broke the eggs that Lu Hao had cooked for Lu Bobo. She was embarrassed and embarrassed and quickly escaped Lu Bobo’s eyes. It fell on the strange scorpion.

Lu Benjie said that this Nicholas egg is actually a special name for the world. In the past life of Yang Lan, this thing was called Tesla's Columbus egg. Of course, Yang Lan had not learned this before. He is also interested now. Look at it.

Not to mention Yang Lan, the other parents are also curious to stretch their necks, if there is still a little restraint, they are expected to mix with the children onlookers.

At this time, Lan Xin, who looked at the broken egg, looked back at God. She curiously asked: "But the eggs are broken, how can I turn it?"

"This question is well asked!" Lu Benjie is like a juggling act. He doesn't know where to change the copper block of an egg. He smiles and shows the little ones. "This machine is not our ordinary eggs, but I saw the egg made of copper in my hand."

Of course, Lu Benjie once again showed the children that the copper egg could not be rotated on the ordinary countertop.

"Next, it is the moment to witness the miracle, the children are optimistic, don't blink!" Lu Benjie deliberately bluffed.

The atmosphere seemed to be tense. The eight children were staring at the wooden rafters and wooden plates, and they were watching the copper eggs in Lu Bobo's hands. The atmosphere didn't dare to breathe.

The same is true, she heard that she would witness a miracle, and two bright big eyes showed excitement.

I saw Lu Bobo put a copper egg on the wooden plate and dialed the pick-up switch below. The sound from the motor came from below. However, at this time, the wooden plate was not moving, not like the propeller just turned fast.

Next, the children saw that Lu Bobo turned the copper egg around and it turned.

But it seems wrong!

Chen Shiyun, who was straightforward, immediately raised his hand and asked in confusion: "Lu Bobo, is not right! This egg is not standing up!"

"Yeah, so I can!" Several little girls around her said it.

But at this time, Lu Weisha exclaimed softly and turned the attention of the children to the past, because when they spoke, the rotating copper egg turned and turned, and stood up. Now!

"It's amazing!" 曦曦I was already big enough, and I was surprised to be bigger. She couldn’t help but turn her head and looked at her father with surprise. father.

The principle of this egg-making device is not complicated. It uses the rotating magnetic field to rotate the egg, and the rotation effect makes the egg find the most suitable rotation posture. Because the egg is oval, only stand up and use the long axis as the center. Only stable.

But after all, it still uses the physical principles that many children have never learned. Lu Benjie once again demonstrated it and began to explain to the children. The little guys heard the clouds and understood some things. One by one, with a small mouth open, stupidly watching, even the clever cockroaches did not show a clear understanding.

When Yang Hao saw it, he smiled and pointed at the wooden raft at the back and said to the children: "Lu Bobo means that our box is a complicated machine that mimics a force we can't see. Called magnetic, help us hold this copper egg, as if we were holding it with our hands, so that it can stand up and turn!"

It turned out to be the case. Although there were still a few slow-moving little heads and confused faces, but there were some young girls like Yang Qiqi and Yu Xiaowei who understood it. He was still in his position, "嘻嘻" Laughing, twisting his little buttocks and saying, "That, that's too great, I can't see it!"

Lu Xiaoyu licked his arm and said innocently: "I know, it must be magic!"

At this time, Lu Benjie greeted the children to come to another short table, so that everyone can be surrounded by a seat, you can watch and walk around without sitting down.

"The one just was just a little magic. Next, we have to come together to witness a more magical magic, a magical magic that you usually can't think of!" Lu Benjie mysteriously.

"There is magic again!" Lan Xin and Chen Shiyun both happily cheered. The other little girls were laughing with excitement, and Nan Zhaoyu jumped with joy.

I saw Lu Benjie moving over a polished mat, made of wood, heavy, not knowing what was inside, and he took out a small gyro, a bit like the last one in the dream space. However, it has not been made into an integrated, yellow bracket, coated with bronze-colored vertebral bodies, but it is also delicate and cute!

Falling into the eyes of the children, it seems like a magical little toy, attracting their attention.

"Which child has played this gyro?" Lu Benjie asked.

Suddenly, including the crickets, several children raised their hands with excitement. However, he was a little embarrassed, raised his hand, and hesitated there and wanted to put it down.

"Is there still a few children who haven't played? Anyone who is willing to come up to show you how this gyro is turned?" Lu Benjie asked with a smile.

At this moment, the little hand was shrunk back, and she still remembered the mistakes she had made. It would be bad if I got rid of it again!

Lu Benjie originally wanted to call her, but huddled back, Lu Benjie was embarrassed to make this privilege too obvious, and he called the more active Chen Shiyun.

There is nothing to say about the gyro, the tactics are similar to the transfer of eggs, but then, Lu Benjie let Chen Shiyun do a demonstration by the way, let the envy that has been waiting to see is broken!

I saw Lu Benjie let Chen Shiyun spin the top on a small lid. Then, Lu Benjie gently lifted the small lid. It was not too tall, only a distance of one or two centimeters. At this time, the top was still rotating on the lid.

Soon, I was surprised to see that Lu Bobo gently put his hand down and the cover was taken away by him, but the top was suspended in the air and kept spinning.

"Magic!" Lu Xiaoyu exclaimed.

"Yes, this is the magnetic magic we created with the same magnetic force. You see, we don't have any support underneath!" Lu Benjie smiled and took a glass and swayed the top. Put it up, then take it away, and the gyro seems to be unaffected at all, and it will continue to float in the air and rotate slightly!

"Great!" Envy is broken.

The little girl regrets some, why not try it bravely? If you can try it together, it will be fun to watch. If the gyro is holding the rotation, you can participate in this "magic". How good?

I missed Lu Bobo's magic!

Thinking of this, I was depressed because of regret, and depressed a small mouth, although there was no buzz, but she stepped back, a little sad to snuggle up with Dad, but also hugged the big hand that Dad vacated, sullenly groaning Counted the fingers of Dad.

What is the principle of magic? He didn't really care. She couldn't listen to Lu Bobo's inexhaustible explanation, just staring at the spinning top.

"Do you want to play too?" Yang Lan saw it, and probably could guess the daughter's careful thoughts and asked with a smile.

I licked my mouth and looked back at my father. I was so embarrassed that I nodded. She was afraid that her father would also laugh at her. She broke the egg and the little head fell down. She showed her shaking little butt. Your own inner thirst.

Yang Lan gently patted the little girl's head and smiled. "Wait a minute, wait for Lu Bobo to finish."

Yang Lan did not say anything. When Lu Benjie finished speaking, he made a sound to let him stop the top, so that every child would take turns to try: "Only by hand, you can have a deeper experience."

I saw Lu Bobo agree, and the little face once again showed a pleasant smile. The queue is nothing, and when it’s my turn, I’m so happy to pull my father’s hand and rely on it: “Hey, I’m playing with you, okay?”

The little girl is still worried about her mistakes! Only when Dad followed, she has confidence.
