Scientists have announced that they have finally figured out how the ancient Egyptians moved those 2.5 ton blocks from the quarry to the areas where they built the pyramids. The answer had been staring them in the face the whole time.
For years, teams of scientists have tried to recreate the feat of the ancient Egyptians using only technology that was used at the time. Everyone who tried failed miserably. It was always assumed that some type of sled must have been used, but what has baffled scientists throughout the years is how did they move them through the sand? Sleds that are transported over the sand tend to have the sand compress in front of the sled and bunch up. Basically, this would stop the sled dead in its tracks and cause it to get stuck.
A team of mechanical engineers from the University of Amsterdam figured out that the ancient Egyptians used buckets of water ahead of the sand to wet it and make it denser, therefore allowing it to support the sled. Where did they discover the idea that the ancient Egyptians did that? It is right in the hieroglyphic shown above by the statue's foot. The ancient Egyptians had teams of people dumping buckets of water. How this escaped scientists and Egyptologists for so many years is as big a mystery as the sleds themselves.
The teams own press release said as following:
"The physicists placed a laboratory version of the Egyptian sledge in a tray of sand. They determined both the required pulling force and the stiffness of the sand as a function of the quantity of water in the sand. To determine the stiffness they used a rheometer, which shows how much force is needed to deform a certain volume of sand. Experiments revealed that the required pulling force decreased proportional to the stiffness of the sand…A sledge glides far more easily over firm desert sand simply because the sand does not pile up in front of the sledge as it does in the case of dry sand."The question that will plague scientists now is how they got such significant amounts of water from the Nile river to the quarries?
