Why Egyptians Watered the Desert #historyshorts

300 of the strongest men in Egypt vs. a tired team and a water boy… who keeps pouring water on the sand. 💧🏜️

It sounds crazy, but it works. Sand with just the right amount of water (about 2–5%) gets roughly twice as stiff, so a heavy sledge slides on top instead of ploughing a hill of sand in front of it. Physicists measured it in 2014: up to half the pulling force. Too much water, though, and it's mud.

And it's on a real wall: an Egyptian tomb painting from about 1900 BC (Djehutihotep) shows a colossal statue on a sledge, rows of men pulling, and one man at the front pouring water.

The story and characters are original; the science and the painting are real.
