When you haul a 3 ton block of stone on a sled across the Egyptian desert it is best to pour water in front of the sled as you go along. The water halts the pile up of sand in front of the sled. Scientists estimate using the water as you go method cut in half the number of paid or unpaid workers pulling the stones.
The picture painted on the wall of the tomb of Djehuihopep showing the transport of a huge statue solved the mystery.
