In the atrium of the Manchester Conference Centre is a large Foucault's pendulum, which normally shows the turning of the earth (the pendulum swings back and forth in a straight line but the earth turns beneath it forcing it to describe an elliptical path). However, for reasons not explained, Manchester have placed an electromagnet in the lower brass sphere which keeps the pendulum swinging but FUBARs the effect described by Foucault.
