Egyptian Pyramids Theory

The huge stones used in the construction of the Egyptian pyramids were transported by being pulled over wet sand on wooden sledges. Each Egyptian pyramid consists of millions of 2.5 to 15 ton blocks. The most common theory for how these blocks were moved is that they were placed on wooden sledges and pulled up sand ramps for elevation. When scientists started to test this theory they realized it was unrealistic because the sand caused too much friction and clumped making it almost impossible for the sledge to be pulled. Although, when a team of Dutch engineers was testing out different methods the Egyptians could have used, they might have found an answer to the problem. They discovered that using water to make the sand wet stopped the sand
