Engineers have simulated an Easter Island Moai and demonstrated that the easiest way to transport a Moai, the many-ton stone statues, is by WALKING THEM.
Using computer modeling and recognizing that the base of the Moai is “d-shaped” and that the statue tends to lean forward, they figure out that using ropes and multiple teams, they could ‘rock’ the statue and ‘walk’ it to its final location from the quarry. View the link and the video of the walking.
Another ancient puzzle solved.
