This physics professor risked his life to show that physics really works. First, he held a pendulum to a glass and gave it a slight push. It swung all the way to the other side and came back with enough force to smash the glass. But then, he stood close to the wall, held the pendulum close to his face, and let it go. Since he didn’t push it, it should come back and stop just short of hitting him. And guess what? Physics works!
