When I worked at the Science Museum in the mid 1960s, one of my duties
was to start the Foucault Pendulum at 2 pm on a Sunday afternoon. Its
purpose was to demonstrate and measure the effect of the earth's
rotation on the direction of swing of the pendulum.

Another much loved exhibit that is no longer on show!

Do you mean Walt or the pendulum? ;-)
