1150 Magical Magnetic Levitation, Xixi's Envy (2/3)
Chapter 1150 Magical Magnetic Levitation, Xixi's Envy (23)
"This is called the Nicholas Egg Cracker!" Hearing Xixi's whisper, Lu Benjie turned to look at her with a smile, and introduced, "Didn't we not be able to spin the eggs upright just now? But this can help us Let the eggs stand up and spin!"
Before Xixi got out of the embarrassment just now, she accidentally flew and broke the egg that Aunt Lu cooked for Uncle Lu. She felt guilty and embarrassed, and quickly avoided Uncle Lu's eyes. It landed on that peculiar box.
The Nicholas egg holder that Lu Benjie mentioned is actually just a special name in this world. In Yang Yi’s previous life, this thing was called Tesla’s Columbus Egg. Of course, Yang Yi did not learn these things in his previous life, and he is still very interested in it now. looking at.
Not to mention Yang Yi, the other parents also stretched their necks curiously. If they were not a little reserved, they probably wanted to hang out with the children and watch.
At this time, Lan Xin, who looked at the broken egg with bone-bone eyes, came back to her senses, and she asked curiously: "But, the egg is already broken, how can it turn?"
"That's a good question!" Lu Benjie conjured up an egg-shaped copper lump out of nowhere as if conjuring, and showed it to the little ones with a smile, "This machine is not using our ordinary eggs, but Use this copper egg that you see me holding in my hand."
Of course, Lu Benjie demonstrated it to the children again. On an ordinary countertop, the copper egg still cannot be rotated and stood up.
"Next, it's time to witness the miracle, children are optimistic, don't blink!" Lu Benjie said deliberately bluffing.
The atmosphere seemed tense, and the eight children were all staring at the wooden box, the wooden plate, and the copper egg in Uncle Lu's hand, not daring to breathe.
The same is true for Xixi, when she heard that she was about to witness a miracle, her two bright eyes showed excitement.
I saw Uncle Lu put the copper egg on the wooden plate casually, and flipped the paddle switch below, and there was a buzzing sound from the motor below. However, at this time, the wooden plate was motionless, unlike the propeller spinning as fast as the propeller just now.
Next, the children saw that Uncle Lu turned the copper egg casually, and it started to spin.
But it seems wrong!
The outspoken Chen Shiyun immediately raised his hand and asked in confusion: "Uncle Lu, that's wrong! The egg didn't stand up!"
"That's right, I can do that too!" The little girls around her all said in one go.
But at this time, Lu Weisha let out a soft exclamation, and diverted the attention of the children, because when they were talking, the spinning copper egg turned around by itself and stood up. up!
"It's amazing!" Xixi's eyes, which were already big enough, opened wider in surprise. She couldn't help but turned her head and looked at her father in surprise, as if she wanted to share her unbelievable feelings with her father. dad.
The principle of this egg stander is not complicated, it is to use the rotating magnetic field to make the eggs rotate, and rely on the rotation effect to make the eggs find the most suitable rotation posture - because the eggs are elliptical, only standing up, using the long axis as the Center rotation is stable.
But after all, this still uses the physical principles that many children have not learned. Lu Benjie demonstrated it again, and then began to explain it to the children. , with their small mouths open, staring in a daze, even the smart Xixi didn't seem to understand.
Seeing this, Yang Yi smiled and pointed to the wooden box behind, and said to the children, "What Uncle Lu means is that our box uses a more complicated machine to imitate a force that we can't see. , called magnetic force, help us hold this copper egg, as if we are holding it with our hands, so that it can stand upright and spin!"
It turned out to be like this, although there were still a few who reacted slowly and tilted their heads in confusion, but Xixi, Yang Luoqi, Yu Xiaowei and other little girls understood, Xixi was still in her position, "hee hee" With a smile, he twisted his little buttocks and said, "Well, that's too powerful, I can't even see it!"
Lu Xiaoyu rubbed Xixi's arm and said innocently: "I know, it must be magic!"
At this time, Lu Benjie called the children to another table that was lower, so that everyone could gather together and observe without sitting down, making it easier to move around.
"The one just now was just a small magic. Next, we will witness an even more magical magic together, which you can't even imagine!" Lu Benjie said mysteriously.
"Look at the magic again!" Lan Xin and Chen Shiyun cheered happily. The other little girls also laughed excitedly, and Nan Zhaoyu also jumped happily.
I saw Lu Benjie bring over a well-polished round cushion, made of wood, heavy, and I don’t know what is stuffed in it, and he took out a small spinning top, a bit like the last spinning one in Inception. But it's not integrated, the yellow bracket and the bronze-colored vertebral body are exquisite and cute!
Falling into the eyes of the children, it seems like some magical little toy has attracted their attention.
"Which kid has played with this spinning top?" Lu Benjie asked.
Immediately, including Xixi, several children raised their hands excitedly, but Xixi was a little embarrassed, raised her hand, and then hesitated whether to put it down.
"Are there any children who haven't played before? Is there any child who is willing to come up and show you how the top works?" Lu Benjie asked with a smile.
At this moment, Xixi retracted her little hand timidly, she was still thinking about the mistake just now, it would be bad if she messed up again!
Lu Benjie originally wanted to call her, but Xixi withdrew her hand. Lu Benjie was embarrassed to show this privilege too clearly, so he called Chen Shiyun, who was more active.
There is nothing to say about turning the top, the technique is similar to turning an egg, but then, Lu Benjie asked Chen Shiyun to do a demonstration by the way, which made Xixi, who had been watching just now, envious!
I saw Lu Benjie let Chen Shiyun spin the top on a small cover, and then, Lu Benjie gently lifted the small cover, not too high, just a distance of one or two centimeters. At this time, the top was still spinning on the cover.
Xixi quickly saw in surprise that Uncle Lu gently retracted his hand, and the cover was taken away by him, but the spinning top was suspended in the air and kept spinning.
"Magic!" Lu Xiaoyu exclaimed.
"That's right, this is the magnetic magic created by us using the same magnetic force. You see, there is actually no support under us!" Lu Benjie still smiled, took a glass, and turned the spinning top horizontally Put it on, and then take it off again, the top seems not to be affected at all, it continues to float in the air and spin slightly!
"It's amazing!" Xixi was so envious.
The little girl felt a little regretful, why didn't she try bravely? It would be great if I could try it myself, just looking at it is not fun, if this spinning top is held up by myself, and I can also participate in this "magic", how great would it be?
I missed Uncle Lu casting magic!
Thinking of this, Xixi pursed her small mouth depressedly because of regret. Although she didn't make a sound, she took a step back, snuggled up to her father sadly, and hugged his father's free big hand, tearing it sullenly. I counted my father's fingers.
What is the principle of magic? Actually, Xixi didn't care too much, she couldn't even listen to Uncle Lu's eloquent explanation, but just stared at the spinning top with longing eyes.
"Do you want to play too?" Yang Yi asked with a smile as he could probably guess what his daughter was thinking when he saw this.
Xixi pursed her lips, looked back at her father, and nodded embarrassingly. She was afraid that her father would laugh at her for breaking the egg, so she lowered her little head again, and used her little buttocks to show off own inner desire.
Yang Yi patted the little girl's head tenderly, and said with a smile, "Wait a minute, wait until Uncle Lu finishes."
Yang Yi did not break his promise, and when Lu Benjie finished speaking, he asked him to stop the spinning top first, and asked each child to try it in turn: "Only by trying it with your own hands can you have a deeper understanding."
Seeing that Uncle Lu agreed, Xixi once again showed a surprised smile on her little face. Queuing is nothing, but when it was her turn, Xixi happily took her father's hand, and said very reliantly, "Papa, I'll play with you, okay?"
The little girl is still worried about her mistakes! Only when her father follows her, can she have confidence.
The plot of the visit is finished, the next chapter is more exciting~
