Using a strobe light in a pitch-black room, I photographed the act of "potting" in the game of tiddlywinks. When a downward vertical force is applied on the "wink" by the "squidger," the mat is compressed to form a "ramp." The mat acts as a spring with a restoring force proportional to the displacement. The spring force propels the wink forward and upward, and also initiates rotation, which is apparent in the photo. Finally, the force of gravity pulls the wink into the pot along a parabolic path.
