Foucault pendulum
On  January 3, 1851, Foucault did the following experiment: He mounted a 2 metre long pendulum, and let it swing, in the basement of his house. On the floor, he marked the axis, along which the pendulum was swinging. After some time, he noticed, that the pendulum no longer swung along the axis he had marked on the floor, but on an different axis. When he tried to explain this, he considered, what could have caused the axis to change. He considered gravity. Gravity could not have caused the axis to change, as it only acts vertically. There were no other forces acting on the pendulum. So: according to Newton's laws, the pendulum did not change the axis it was swinging in. So it was the floor (or the earth) that changed this axis, because it rotated.
