"This is called Nicholas Egg Stander!" Lu Benjie turned to smile at her and whispered to Xi Xi, introducing, "Aren't we just not able to spin the eggs upright? But this Can help us make the eggs stand and spin! "
Xi Xi has not escaped from the embarrassment just now. She accidentally drove and broke the eggs that Aunt Lu cooked for Uncle Lu. She was guilty and quickly escaped Uncle Lu from embarrassment. His eyes fell on the peculiar box.
The Nicholas egg riser that Lu Benjie said is actually just a special name for this world. In Yang Yi ’s previous life, this thing was called Tesla ’s Columbus egg. Of course, Yang Yi did not learn this in his previous life. He is also now Watch with interest.
Do n’t mention Yang Yi, the other parents stretched their necks curiously. If they were not a little reserved, they probably wanted to be around with the children.
At this time, Lan Xin, who was staring at the broken egg, recovered, she asked curiously: "However, the eggs have been broken, how to turn it?"
"This is a good question!" Lu Benjie resembles a trick. I do n’t know where to get an egg-shaped copper block. I smiled and showed it to the little ones. "This machine does not use our ordinary eggs. , But use the eggs made of copper that everyone sees in my hand. "
Of course, Lu Benjie still demonstrates to the children again, on the ordinary countertop, this copper egg still cannot stand upright.
"Next, it is a moment to witness the miracle. The children are optimistic, don't blink!" Lu Benjie said deliberately bluffing.
The atmosphere seemed tense. The eight children were staring closely at the wooden box, the wooden plate, and the copper egg in Uncle Lub ’s hand. The atmosphere did not dare to breathe.
Xi Xi is the same, she heard that she is about to witness a miracle, and her two bright eyes show her excitement.
I saw Uncle Lu put the copper eggs on the wooden plate and set aside the paddle switch below. A humming noise came from the motor below. However, at this time, the wooden plate was motionless and did not spin as fast as the propeller just now.
Next, the children saw that Uncle Lub turned the copper egg casually and it spun up.
But it seems wrong!
Straight-talking Chen Shiyun immediately raised his hand and asked in confusion: "Uncle Lu, right! This egg hasn't stood up yet!"
"Yeah, so I can too!" The little girls around her said lip-sharply.
At this time, Lu Weisha exclaimed softly, and turned the attention of the children back, because just when they were talking, the rotating copper egg turned around by itself, Stand up!
"It's amazing!" Xi Xi's eyes were big enough, and she opened her eyes in surprise. She couldn't help turning her head and looked at her father with surprise, as if she wanted to believe her unbelievable moment. Share the mood with dad.
The principle of this egg stand is not complicated. It uses the rotating magnetic field to rotate the egg, and the rotation effect allows the egg to find the most suitable rotation posture-because the egg is elliptical, only standing up to use The long axis rotates as the center to stabilize.
But after all, it still uses the physical principles that many children have not learned. Lu Benjie demonstrated it again and began to explain to the children endlessly. The little guys listened to the fog and understood some It's not clear, one by one, with small mouths open, watching dimly, even the clever Xi Xi didn't seem to understand.
Yang Yi saw this and smiled and pointed to the wooden box at the back, and said to the children: "Lubber meant that our box is a more complicated machine that imitates a look we ca n’t see. The strength, called magnetic force, helps us hold this copper egg as if we were holding it by hand, so that it can stand upright! "
It turned out to be the case. Although there were a few people who were slow to skewer their heads and looked confused, Xi Xi and young girls such as Yang Luoqi and Yu Xiaowei understood that Xi Xi was still in his place. " "Hee hee" smiled, twisted his little ass, and said: "Then, that's too great to see!"
Lu Xiaoyu rubbed Xixi ’s arm and said naively: "I know, that must be magic!"
At this time, Lu Benjie greeted the children to another lower table, so that everyone can gather around and watch without sitting down, which is convenient for walking.
"It was just a little magic just now. Next, we have to witness a more magical magic, a magical magic that you can't even think of!" Lu Benjie mysteriously.
"There is magic again!" Lan Xin and Chen Shiyun cheered happily. The other little girls laughed excitedly, and Nan Zhaoyu jumped happily.
I saw that Lu Benjie moved to a smooth polished round pad, made of wood, heavy, I do n’t know what was stuffed in it, and he took out a small gyro, a bit like the final rotation in the dream space The one, but it is not made into a unified one, the yellow bracket and the vertebral body painted with bronze color are also exquisite and cute!
Fall into the eyes of the children, as if they are like some magical little toys, which attracted their attention.
"Which kid has played this gyro?" Lu Benjie asked.
Sometimes, including Xixi, several children raised their hands excitedly, but Xixi was a little embarrassed, raised her hand, and then hesitated to put it down.
"A few children have n’t played yet? Which one would like to show you how this gyro turns?" Lu Benjie asked with a smile.
At this moment, Xi Xi shrank her small hand back timidly, and she still remembered the mistake she made just now. It would be bad if it broke again!
Lu Benjie originally wanted to call her, but Xi Xi withdrew her hand. Lu Benjie was embarrassed to show this privilege too obvious, and named Chen Shiyun, who was more active.
There is nothing to say about the spinning top, the trick is almost the same as turning the egg, but next, Lu Benjie asked Chen Shiyun to make a demonstration, which made Xi Xi who had been watching just now envy the bad!
I saw that Lu Benjie asked Chen Shiyun to spin the top on a small lid. Later, Lu Benjie gently lifted the small lid. It was not too high, just a distance of one or two centimeters. .
Xi Xi quickly and surprised to see that Uncle Lu gently lowered his hand and the cover was taken away by him, but the gyro actually floated 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 actually have no support under this!" Lu Benjie also smiled, took a glass, and will rotate horizontally Put the gyroscope on, and then take it away again. The gyroscope seems to be unaffected at all, and it continues to hover in the air with a slight swing!
"It's amazing!" Xi Xi envyed the bad.
The little girl regrets a bit, why do n’t you try it bravely? It would be nice if I could try it together. It ’s not fun to watch alone. If this gyro is held up by itself, how can I participate in this “magic”?
I missed Uncle Lu's magic!
Thinking about this, Xi Xi all groaned her small mouth because of regret. Although she didn't say anything, she took a step back and snuggled up with her father a little, but also hugged his big hand that was empty. The ground broke and counted his father's fingers.
What is the principle of magic? In fact, Xixi didn't care much. She couldn't hear Uncle Lub talking incessantly, just staring at the spinning top.
"Do you want to play too?" Yang Yi asked, smiling, probably guessing her daughter's careful thinking.
Xi Xi squeezed her small mouth and looked back at her father. She nodded slightly embarrassedly. She was afraid that her father would also laugh at her. She smashed the egg, and her small head lowered again. To show their inner cravings.
Yang Yi patted the little girl's head gently and smiled: "Wait, wait for Uncle Lu to finish."
Yang Yi didn't have any words. After Lu Benjie finished speaking, he made a noise and asked him to stop the gyro first, so that every child could take turns to try: "Only by hand can you have a deeper experience."
Xi Xi saw that Uncle Lu agreed, and her small face again showed a pleasant smile. Waiting in line is nothing. After waiting for his turn, Xi Xi took his father's hand happily and said: "Baba, I will play with you, OK?"
The little girl is still worried about her mistakes! Only dad followed her, she was confident.
