How were the PYRAMIDS built?

Pyramids are one of the most extraordinary constructions of the ancient world. Since ages we were trying to find out how these pyramids were constructed and how they did manage to pile all those heavy stone. We had many theories too.. But in 2014 Physicists found the answer!

So, the recipe was simple water and sand! The ancient Egyptians who built the pyramids may have been able to move massive stone blocks across the desert by wetting the sand in front of a contraption built to pull the heavy objects.

Physicists at the University of Amsterdam investigated the forces needed to pull weighty objects on a giant sled over desert sand, and discovered that dampening the sand in front of the primitive device reduces friction on the sled, due to which the Egyptians were able to move heavy rock each weighing nearly ton.

But the proportion of water and sand is important. “If you use dry sand, it won’t work as well, but if the sand is too wet, it won’t work either,” Bonn said. “There’s an optimum stiffness.”

The picture below was actually an Egyptian painting explaining the construction of a pyramid, but until nowย it was mistakenly interpreted to some other painting explaining water purification.
