Comprises five steel balls of equal mass, lined up and in contact with each other. When the first ball is raised and released, it transmits the force of motion through the stationary balls upon striking its neighbour, causing the final ball to arc. This phenomenon does not occur if you place a disk of deforming material between the balls.
