A new study shows that the ancient Egyptians who built the pyramids, may have moved the massive stone blocks through the sand desert watering, leaving the soil consistently to pull heavy objects. Some physicists at the University of Amsterdam investigated the necessary strength to pull heavy objects on a giant sleigh on the desert sand, and found that moistening the sand in front reduces friction on the sled, making it easier to carry. The results help to answer one of the most enduring mysteries of history, as the Egyptians were able to accomplish the seemingly impossible task of building the famous pyramids? To make their discovery, the researchers took painted murals in the ancient tomb of Djehutihotep, which in 1900 BC describes 172 men carrying a huge statue using ropes attached to a sled. In the drawing, a person can be seen standing in front of the sled, pouring water on the sand, said lead study author Daniel Bonn, a physics professor at the University of Amsterdam.
Each pyramid block weighs about 2.5 tons.

About where to get water ? Many believe that the nearest source for this would be the Nile Bonn and his colleagues built miniature sleds and tried to pull heavy objects through sand trays. When the researchers drag sleds on the dry sand, they noted that they would need ever more power to pull them . Addition of water in the sand, however, the sledges were able to slide easily over the surface. This is because the water creates a firm, hard ground.
