The giant pendulum swings in a straight line back and forth and the earth underneath it rotates. As the earth rotates the big panel underneath that show the time spins but the pendulum just keeps going straight. This proves the earth is the one spinning. When we first saw the pendulum it was swinging over the 12.30 part, and when we came back an hour later the earth had certainly moved as it was swinging over the 1.30 part.
Because we were in Paris it was spinning clockwise, but in NZ it would be spinning anti clockwise.
