I heard a very good story from a guy at work I would like to test. He said his father was in Egypt after the war with the army. And some locals told him you could rest a coin on one/ any of the blocks in the pyramid and it would move very slowly. Said he had to mark it, it moved so slow..... it may need to be a silver or pure copper coin, he didn't know the details.

He said his dad didn't bullshit, and I have known this guy for many years he doesn't bullshit either.

Check it out next time you are their please.
