In a study led by Prof. Daniel Bonn of the University of Amsterdam, the ancient Egyptians use of simple tricks to move the giant statues and stone pyramid with wet sand on a sled track.
The findings are published in the journal Physical Review Letters, in terms of construction of the pyramids, ancient Egyptians had to transport large blocks of stone and sculpture across the desert. They put a heavy stone pieces on a sled while other workers to pour water on the surface of the sand.
Until now scientists are still questioning how the ancient Egyptians move the pieces of stone pyramids of Egypt and large-sized sculptures. Logically, each piece of stone weighing up to tens of tons pyramid and could not be moved by human power. Moreover, a built up area is located in the desert, of course, very difficult where the impetus to use without wheel feels much heavier than a hard surface.
However, scientists from University of Amsterdam tries unmasked the secret of ancient Egyptians, where this method has previously unthinkable and was written in the text of the wall. This ancient instructions are then tested in a laboratory to solve the mystery of the pyramids of stone removal.
The ancient Egyptians probably aware of this trick is very useful, It is found on the tomb wall paintings Djehutihotep which clearly shows the person standing in front of the sled that is pulled and put water in front of him.
To test this hypothesis, the researchers tested the theory in a laboratory version involving sled and sand. Sled pull force required and stiffness turned into wet sand in the desert. In determining the stiffness of the surface of the sand, scientists using a rheometer which shows how much power is needed to destroy a certain volume of sand.
Sled pulling force decreases proportional to the stiffness of sand. This trick uses a small water droplets that bind sand grains together with the correct amount of water droplets, the desert approximately twice as stiff as dry sand. The sled is much easier to control where the sand does not accumulate in front of the sled wheels as in the case of dry sand.
