Pendulum of hypnosis:

“My findings about the Foucault pendulum may very well astonish you…The surprising truth is that all Foucault pendulums are fakes. Most of them are fakes because they are forced to do what they do, rather than doing what comes naturally, and all the rest of them are fakes insofar as they are used as proof of the earth’s [supposed] rotation."

Er. Richard G Elmendorf,
After 20-year investigation of the Foucault pendulum in 1994.
