I made science magic

Chapter 141 Lynn’s Pendulum Experiment (Please subscribe)

"Okay! It's finally time for us to take the stage."

Alok and others, who had been watching below for a long time, were already excited. After getting Lin En's approval, they immediately ran to the high platform holding a large box.

Yolande stepped forward and took a look with some uneasiness. The big box contained some strange things. The most conspicuous thing was a big iron ball with a protruding sharp needle embedded at the bottom.

"Masters, please allow me to use magic to make certain changes here, so that the effect of the experiment can be more intuitive!" Lin En said.

"If you think this can be of any help!" Raphael nodded and agreed.

Lin En immediately used [Fossils to Mud] to turn the large stone bricks under his feet into fine sand. Then he asked Jonny and others to piece together the stone slabs placed in the box, forming a giant outside of the high platform.

of disc.

Precisely three hundred and sixty scales are divided into the corners of the disk, and a wooden stick is placed in front of each scale.

Finally, Linn asked the wizard who had developed flying magic to hang the iron ball on the ceiling of the seminar hall with a wire rope.

Due to the need to demonstrate magic, the hall of the entire magic seminar is not only wide, but also built very high, with the ceiling being sixty meters above the ground.

The iron ball weighing 30 kilograms was tied by a slender wire rope only about ten centimeters away from the sand. The sharp needle protruding from below had sunk into the sand.

"What are you trying to do?" Yolande was completely confused. He couldn't understand the other party's operation at all.

The other wizards on the field also had confused expressions on their faces.

"Do an experiment!" Linn waved to Alok and others to stand aside, and then asked. "Mr. Yolande, what do you think will happen if you push this iron ball hard?"

"The iron ball will be thrown out and then swing back and forth in a straight line. Needless to say?" Yolande responded impatiently.

"I don't think so." Lin En shook his head, "Because you have ignored a very important factor, that is, the continent under our feet is rotating, and the geostrophic deflection force generated will inevitably affect the swing of the iron ball, so this

When the pendulum swings, it will continue to deflect and rotate around this disk."

"Absurd!" Yolande doesn't believe in the so-called geostrophic deflection force, let alone such an outrageous thing as the continent's rotation. That's a complete fallacy!

Thinking like this, Yolande's eyes were fixed on him, for fear that the other party would play some tricks during the experiment.

Linn didn't even use magic. Instead, he pulled the iron ball to the zero mark of the sand table, then let go of his hand, letting the iron ball swing freely with the help of gravity.

The steel wire rope, which was nearly sixty meters long, was stretched straight due to the weight of the iron ball. Under the action of gravity, it caused a gust of wind and hit the wooden bar on the opposite side that belonged to the one hundred and eighty mark.

Just like Yolande said, the path of the iron ball is indeed a straight line.

The eyes of all the wizards in the room were focused on the pendulum. Because the wire rope binding the iron ball was very long, the iron ball swung back and forth not very fast, but it was very regular, and it did not swing as Lin En said.

Deflect away.

Yolande waited for a while but saw no change. He looked at Linn and said mockingly, "Where is the phenomenon of the pendulum rotating around the disk you just mentioned? Why didn't I see it?"

"You were too impatient and didn't observe carefully enough, so you couldn't see it." Linn sighed.

Yolande was very annoyed. He was not blind. Couldn't he still tell whether this thing was spinning or not?

At this moment, a cry of surprise suddenly came over.

"It's off, the trajectory is really off!"

Several great wizards stood up from their seats and stared closely at the sand table under the pendulum.

Where is the deviation? Yolande also looked in the direction of everyone's gaze, and was shocked to realize that the trajectory left by the fine needle at the bottom of the iron ball on the sand table was not a completely straight line, and there would be a slight deviation every time it went back and forth.

.

It's just that this deviation is so small that it can't be seen with the naked eye. It can only be judged by the trajectory left by the pendulum across the sand table!

Boom...

With a slight muffled sound, the wooden bar representing one hundred and eighty-one degrees was knocked down by the iron ball, and then the pendulum knocked the opposite wooden bar representing one hundred and eighty-one degrees to the ground.

Whether it is the traces left on the sand table or the knocked down wooden bars, there is no doubt that the pendulum is really moving slowly, and it is not wandering around, but deviates regularly to the left.

"The wind, the wind must have blown it!" A wizard from the prophecy school shouted loudly.

Yolande also thought of this immediately, but before he could speak, he heard Philip on the side saying mockingly.

"This is indoors, where is the wind coming from?"

"Even if there is no strong wind, the air is still flowing, no matter how subtle the impact is, it will have an impact!" Yolande said with a smile on his neck.

In short, he never believes in something that is not magical at all, such as the rotation of the planet!

"Masters, since Mr. Yolande is suspicious, please turn this area into a vacuum." Lin En suggested with a smile.

This time it was August who took action. He was also very curious about such an interesting pendulum deflection phenomenon, so he followed Linn's request and extracted all the elements in the entire disk without affecting the pendulum as much as possible.

separated, forming a vacuum field...

Yolande held his breath and stared at the disk intently, eager to see new changes in the trajectory of the iron ball.

Ten seconds...thirty seconds...one minute, the pendulum still moved firmly to the left, and even the amplitude of each deflection was exactly the same as before.

Soon the wooden bars corresponding to the two scales and the one hundred and eighty-two scale were also pushed to the ground.

"There must be no wind now!" Philip said in a sinister tone.

Yolande's face turned green and red. He opened his mouth but could not speak. He did not use magic and there was no interference from the wind. Where did the power to deflect the pendulum come from?

Is it possible that there really is a so-called geostrophic deflection force?

As time went by, more and more wooden bars fell down. In the seminar hall, the wizards who were originally sitting in their seats had all gathered around, blocking the high platform with water, just to observe this at close range.

Amazing experiment...

"This is actually true. The continent beneath our feet is moving. It is really moving!" A witch screamed loudly.

"It's incredible. This is simply a miracle in the history of magic. We actually live on a constantly rotating planet!" Raphael also said with emotion.
