I Made Scientific Magic

  Chapter 141 Lynn's Pendulum Experiment (Subscribe)

   "Alright! It's finally time for us to appear on stage."

   Eloque and the others, who had been watching for a long time, were already full of enthusiasm. After getting Lynn's approval, they immediately ran to the high platform with a big box in their arms.

   Yolande leaned forward with some anxiety and took a look. The big box contained some strange things. The most conspicuous thing was a big iron ball with a protruding needle embedded in it.

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

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

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

   There are precisely 360 scales differentiated on the corners of the disc, and a wooden stick is placed in front of each scale.

  Finally, Lynn asked the previous wizard who had researched the magic of flying to hang the iron ball on the ceiling of the seminar hall with a steel 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 fully sixty meters above the ground.

  The iron ball weighing 30 kilograms was tied by a slender steel wire rope just a few centimeters away from the sand, and the sharp needle protruding from the bottom had already sunk into the sand.

   "What are you going to do?" Yolande was completely confused, he couldn't understand the opponent's operation at all.

  The rest of the wizards on the field also looked confused.

   "Do an experiment!" Lynn waved his hand to let Ai Luoke and the others 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, so needless to say?" Yolande responded impatiently.

"I don't think so." Lynn shook his head, "Because you have overlooked a very important factor, that is, the continent under our feet is rotating, and the resulting geostrophic deflection force will inevitably affect the swing of the iron ball, so this When the pendulum is swinging, it will constantly deflect in the direction and rotate around this disc."

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

  Thinking like this, Yolande stared at him intently, for fear that the other party would play some tricks during the experiment.

  Lin En didn't even use magic. Instead, after pulling the iron ball to the zero mark position on the sand table, he let go of his hand directly, allowing the iron ball to swing freely with the help of gravity.

  The steel wire rope with a length of nearly 60 meters was stretched straight due to the weight of the iron ball. Under the action of gravity, there was a gust of wind, and it hit the opposite wooden bar belonging to the 180 scale.

   Just like Yolande said, the iron ball's traveling route is indeed a straight line.

All the wizards in the audience focused their attention on the pendulum. Due to the very long steel wire rope that binds the iron ball, the iron ball swings back and forth not fast, but it is very regular, and it is not as Lynn said. Deflect away.

   Yolande waited for a long time and saw no change. Dang even looked at Lynn 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 anxious, and your observation skills were not careful enough, so you couldn't see it." Lynn said with a sigh.

   Yolande was very annoyed. He is not blind. Can't he see if this thing is turning?

   Right at this moment, an exclamation suddenly came.

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

   Several great wizards even stood up from their seats, staring closely at the sand table under the pendulum.

  Where is it off? Yolande also looked in the direction of everyone's gaze, only to realize that the trace left by the thin needle at the bottom of the iron ball on the sand table is not a completely straight line, and there will be a slight deviation every time it goes back and forth.

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

  Boom...

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

  Whether it is the marks left on the sand table or the wooden strips that have been pushed down, it undoubtedly proves that the pendulum is really moving slowly, and it is not swaying around, but deviates to the left direction regularly.

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

   Yolande also immediately thought of this, but before he even opened his mouth, Philip on the side said mockingly.

   "This is indoors, where does the wind come from?"

   "Even if there is no strong wind, the air is still flowing, and even the slightest impact is still an impact!" Yolande said, poking his neck.

  In short, he never believed in such non-magic things as planetary rotation!

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

This time it was Ogst who made the shot. 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 disk without affecting the pendulum as much as possible. away, forming a vacuum field...

   Yolande held his breath, staring 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 deflected firmly to the left, and even the magnitude of each deflection was exactly the same as before.

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

   "There must be no wind now!" Philip said eccentrically.

  Yurand's face was bluish, and he opened his mouth but couldn't speak. He didn't use magic, and there was no wind interference. So where did the power to deflect the pendulum come from?

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

With the passage of time, more and more wooden slats fell down. In the hall of the discussion meeting, the wizards who were sitting in their seats had already gathered around and blocked the water around the high platform, just to observe this at close range. Fantastic experiment...

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

   "It's unbelievable, this is simply a miracle in the history of magic, we actually live on a constantly rotating planet!" Raphael also said with emotion.
