Have you ever wondered how to directly prove the Earth's rotation in a room? Our classic scientific installation, the Foucault pendulum, will visually demonstrate this cosmic wonder through a seemingly simple yet profoundly physics-based oscillation. The exhibit consists of a meticulously calibrated model of the Foucault pendulum, a precise graduated disc, and a transparent railing. Once the pendulum begins to swing, it will continue to oscillate regularly under the influence of gravity. The most amazing phenomenon will then slowly unfold: due to the inertial effect of the Earth's rotation, the plane of the oscillation will slowly and steadily deflect over time. Visitors can clearly observe the rotational changes in the oscillation trajectory through the markings on the disc, personally verifying this classic experiment proving the Earth's rotation. Visitors at different latitudes will also learn how geographical location affects the direction and speed of the deflection.
