He supposedly claimed he discovered the secret of the Pyramids of Egypt. He could move massive blocks of limestone without help or even block and tackle..............
I know the story and found it very interesting that this guy who weighed in at about 90 pounds did what he did, but once he discovered their secret, he did a fabulous job. There are pictures of the box on a tripod covered up. The FEDS have had it for a long time now.
I saw a video on a guy who moved a barn all on his own. He demonstrated the technique with large boulders as well. The way he did it was by placing a stone under the object he intended to move, and having a lever in which to sway and rotate the boulder/barn in a back and forth manner. Video should still be findable on YouTube if interested.
