SCIENCE lovers are invited to go along to ‘swinging sessions’ at a church on the outskirts of Chester.

A 52ft-long re-creation of Foucault’s Pendulum is in action at St Peter’s Church, Waverton, on Mondays, Tuesdays and Wednesdays for school groups and any interested parties to view.

The experiment is the work of churchgoer Andrew Bate, the chairman of Chester Astronomical Society and a beef farmer, of Hatton Farm, Waverton.

Like Foucault’s original set-up of 1851 in Paris, the pendulum remains the only way of visually demonstrating the rotation of the Earth.

Andrew, 57, said: “This rotation is shown by the plane in which the pendulum swings slowly rotating or precessing with respect to the floor under it. This rotation is in a clockwise direction for us but what is actually happening is that the Earth is rotating in an anti- clockwise direction carrying the floor with it.”

Foucault had a metal pointer which dragged in sand to leave a track, while the Waverton pendulum supports a laser pointer projecting a spot of light on to a screen.
