A Foucault Pendulum demonstrates the earth's spin on its axis. It's also very rhythmic and soothing, even in a museum as crowded as the Chicago Museum of Science and Industry. Several people have complained that it's too long, so I did some fast forwarded versions. Hope that helps!

A Foucault Pendulum is a large mass suspended from a long line. with an unconfined swing direction. The first was created at the Pantheon in Paris.

The rotation of the pendulum's swing is formulaic. At the North or South pole, the rate of rotation is 1x for each 24 hours. At different latitudes, the rate (in degrees) ratio (to 360 degrees) is the sine of the latitude.

This last information was obtained from the article on Leon Foucault on the Encyclopaedia Brittanica (Encyclopedia Brittanica).
