A substantial Foucault's pendulum displayed at the Príncipe Felipe Science Museum of the City of Arts and Sciences in Valencia, Spain. In this configuration, a small ball-and-stick model is gradually tilted approximately every 30 minutes due to the Earth's rotation beneath the pendulum's fixed plane of motion.
1851: Foucault’s Pendulum – Demonstrating Earth’s Rotation

Jean Bernard Léon Foucault's 1851 experiment, using a simple pendulum, provided clear, observable proof of Earth's rotation. This groundbreaking demonstration, utilizing basic principles of physics, transformed our understanding of Earth's dynamics
