Twirling a penny in a lampshade from "Popular Scientific Recreations" by Gaston Tissandier (ca. 1890).
A lampshade is grasped in the right hand and, with the left hand, a coin is twirled on its edge into the shade. At the same time, the shade is rotated in the right hand in the opposite direction. The coin should roll around without falling due to centrifugal force.
