"Okay! It's finally time for us to make the scene. ”

Elok and the others, who had been watching it for a while, were already enthusiastic, and after getting Lynn's approval, they immediately ran to the high platform with a big box.

Yolande stepped forward to take a look with some uneasiness, and the big box contained some strange things, the most conspicuous of which was a large iron ball, and a protruding needle was embedded at the bottom.

"Masters, please allow me to use magic to modify this place to a certain extent, so that the effect of the experiment can be more intuitive!" Lynn spoke.

"If you think that can help!" Raphael nodded and agreed.

Lynn immediately cast [Fossil to Mud], turning the large stone bricks under his feet into fine sand, and then asked Jonny and the others to put together the stone slabs placed in the box, forming a giant disc on the outside of the high platform.

Precise three hundred and sixty scales were divided into the corners of the disk, and a wooden stick was placed in front of each scale.

Eventually, Lynn asked the wizard who had developed the magic of flying to hang the ball from the ceiling of the seminar hall with a wire rope on it.

Due to the need to demonstrate magic, the entire hall of the magic seminar was not only large, but also very high, with the ceiling reaching a full sixty meters from the ground.

The iron ball weighing 30 kilograms was tied to a slender wire rope only more than ten centimeters away from the sand, and the sharp needles protruding below had fallen into the sand.

"What are you doing here?" Yolande was completely confused, he couldn't understand the other party's operation at all.

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

"Do an experiment!" Lynn waved Elok to the side, then asked. "Mr. Yoland, what do you think will happen if you push this iron ball harder?"

"Needless to say, the ball of iron will be thrown and swing back and forth in a straight line?" Yolande replied impatiently.

"I don't think so." Lynn shook his head, "Because you ignore 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 when this pendulum swings, it will constantly deflect the direction and rotate around this disk." ”

"Ridiculous!" Yolande doesn't believe in any so-called geostrophic deflection force, let alone such an outrageous thing as continental rotation, which is completely fallacious!

Thinking like this, Yoland's eyes were staring at each other, for fear that the other party would do some tricks during the experiment.

Lynn didn't even use magic, but after pulling the iron ball to the zero scale position of the sand table, he directly let go of his hand and let the iron ball swing freely with the help of gravity.

The wire rope with a length of nearly 60 meters was stretched straight because of the weight of the iron ball, and under the action of gravity, a gust of wind was heard, hitting the wooden bar belonging to the 180th scale on the opposite side.

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

The eyes of all the wizards in the audience were focused on this pendulum, because the wire rope that bound the iron ball was very long, the iron ball did not swing back and forth quickly, but it was very regular, and it did not deflect as Lynn said.

Yoland waited for a while without seeing any change, when he looked at Lynn and said mockingly. "What is the phenomenon of the pendulum rotating around the disc that you just mentioned? Why didn't I see it? ”

"You're in too much of a hurry, and you're not observant enough, so you can't see it." Lynn said with a sigh.

Yolande was very annoyed, he wasn't blind, this thing didn't turn, couldn't he still see it?

At this moment, an exclamation suddenly came.

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

Several archwizards even got up from their seats, staring closely at the sand table under the pendulum.

Where's the deviation? Yolande also looked in the direction of everyone's gaze, and then realized that the thin needle at the bottom of the iron ball left a trajectory on the sand table that was not completely straight, and there would be a slight deviation every time he went back and forth.

It's just that this deviation is so small that it can't be seen by the naked eye alone, and 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 the scale was knocked down by the iron ball, and then the pendulum knocked the wooden bar representing the 181th degree on the opposite side to the ground.

Whether it is the marks left on the sand table or the toppled wooden bars, there is no doubt that the pendulum is really moving slowly, and it is not swaying around, but it is regularly deviating in the direction of the left.

"The wind, it must have blown it!" A wizard of the School of Prophecy shouted.

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

"It's indoors, where does the wind come from?"

"Even if there is no strong wind, the air is moving, and even the slightest impact is an impact!" Yolande said with a stiff neck.

In short, he would never believe in the rotation of the planet and such a thing as no magic at all!

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

This time it was Ogst who shot it, and he was also very curious about such an interesting pendulum deflection phenomenon, so he followed Lynn's request to extract all the elements in the entire disc without affecting the pendulum as much as possible, forming a vacuum field......

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

Ten seconds... Thirty seconds... For a minute, the pendulum was still firmly shifted to the left, and even the magnitude 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 scales were also pushed to the ground.

"There's no wind now!" Philip said in a weird way.

Yoland's face turned red, he opened his mouth but couldn't speak, no magic was used, and there was no interference from the wind, so where did the power that deflected the pendulum come from?

Could it be that there really is a so-called geostrophic deflection force?

As time went by, more and more wooden bars fell, and in the hall of the seminar, the wizards who had been sitting in their positions had gathered around them, and the water around the high platform was blocked, just to observe this magical experiment up close......

"This turned out to be true, the continent under our feet is moving, it is really moving!" A witch screamed loudly.

"It's incredible, it's a miracle in the history of magic, we really live on a planet that keeps turning!" Raphael also said with emotion.
