I saw on the You Tube a fellow made a pyramid shape form out of common soda straws glued together.
Then he secured a string to the top of the four sided pyramid and let it dangle.
The pyramid kept turning in a ""counterclockwise"" fashion until the string could not twist any more.
I don't believe it was a hoax where the string was pre twisted to turn that way.
I wonder if anyone has ever tried that using a small ball chain from a light bulb receptacle?
Noting stopping the turning movement now.
