I broke out of the grave and was broadcast live by Yearning

Everyone looked at Ye Xuan in disbelief.

Ye Xuan smiled: "I not only know how the pyramids are built."

"And when the ancient Egyptians built the pyramids..."

"I'll be watching from the side!"

…………

I broke out of my grave and was broadcast live by Yearning!

Chapter 89 How the Pyramids Are Built

The voice fell!

Everyone was stunned!

The old man not only knows how the pyramids are built,

And when building,

Still watching? ? ?

That sounds outrageous! !

But this also completely stimulated everyone's curiosity.

"Grandpa, then tell us quickly."

"How are the pyramids built?"

Sister Zifeng and Teacher Huang spoke one after another.

The water friends also had their hearts pounding.

These are the eight unsolved mysteries of the world!

Could it be that the old man wants to solve this puzzle that has plagued mankind for thousands of years?

"How to build it, of course it uses the buoyancy of 'water'!"

Ye Xuan asked: "You all don't know, is the Nile River upstream of the pyramid?"

"When the pyramid was built, a canal was built between the quarry and the pyramid, and the boulders were transported by the buoyancy of the water."

However, Ye Xuangang finished speaking.

He was objected by Teacher Huang: "Master, your argument is untenable!"

"We all know that a stone is heavier than water. If you put a stone in water, the stone must sink to the bottom of the water?"

"How could the stone still float on the water??"

Teacher Huang touched his head and said.

"Yeah, that doesn't make sense!"

"I don't think it was built that way..."

"This statement feels even more unreliable than the principle of leverage!"

The water friends discussed one after another.

"Actually, the ancients were much wiser than you imagined!"

Ye Xuan looked around at everyone, and said slowly:

"The problem you mentioned is not a problem at all, because as long as a heavy object is tied to an object with great buoyancy, the stone can float on the water."

"For example, the sheepskin rafts that are still used in some areas of Huaguo."

"The ancients at that time tied many objects with huge buoyancy like sheepskin airbags to the boulders to make the boulders float."

"Then drag it with livestock on the shore so the boulders can move forward easily."

After listening to Ye Xuan's explanation.

Everyone showed stunned expressions!

"So it is!"

"However, the problem has arisen again. Such heavy stones have to be piled into the shape of a pyramid..."

Everyone still felt that it didn't make sense: "How can such a heavy boulder be transported up?"

It can't be moved up, can it? ?

You must know that any boulder that makes up the pyramid weighs more than ten tons!

"It's very simple!"

Ye Xuan patiently explained: "Everyone knows that water flows from top to bottom, but the ancient Egyptians just went in the opposite direction and let the water "flow" upward."

"Workers built many of the gates, taking advantage of the upward buoyancy effect of water on objects, pushing boulders upward."

"When the first gate is opened, the stone will float to the second gate, then close the first gate and open the second gate, and the stone will float to the third gate..."

"By analogy, the water can send these floating stones to the top of the tower in sections."

"Workers only need to remove the boulder from the raft at the expected construction location!!"

After listening to Ye Xuan's words.

Everyone is shocked!

They all sighed, what a smart way!

"No wonder I saw news that many experts found some creatures that only grow in rivers on the boulders above the top of the pyramids."

"It turns out that water is used to transport boulders here!"

"Using buoyancy to solve the transportation of huge stones and build such a magnificent building, the wisdom of the ancients is much higher than we imagined."

"Awesome, so the pyramids were built like this!"

"Thank you, old man, for solving a problem that I have been unable to figure out!"

at the same time.
