7 April: Through the middle
Foucault's pendulum, named after the French physicist Léon Foucault, is a simple device conceived as an experiment to demonstrate the rotation of the Earth. While it had long been known that the Earth rotated, the introduction of the Foucault pendulum in 1851 was the first simple proof of the rotation in an easy-to-see experiment.
Pendulum swings from one side to the other, always passing through the centrepoint.

Cool to watch, and there's always a cheer when it knocks over one of the wooden pegs!
