Amazing Foucault’s pendulum at Pantheon in Paris, France 🇫🇷

The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. A long and heavy pendulum suspended from the high roof above a circular area was monitored over an extended time period, showing that its plane of oscillation rotated.
In 1851 Foucault made his most famous pendulum when he suspended a 28-kilogram brass-coated lead bob with a 67-metre long wire from the dome of the Panthéon, Paris.
