In 1851 the French physicist Jean Bernard Léon Foucault, showed that the plane of oscillation of a pendulum tends to swing rotated clockwise regardless of the motion of the pivot; it was the first demonstration of the Earths rotation. The path of each round always crosses the center and keeps rotating smoothly, just like an art work by the nature. It created a "pendulum mania" at that time. Today, Foucault pendulums are also popular displays in science museums and universities.
In real Foucault pendulum, the swing is observed to rotate 360 degrees clockwise in about 32 hours. In this app the rate is greatly exaggerated so we neednt wait that long to observe and draw.
