The Catching Arena is an open box made of black acrylic plastic, enclosed by white plastic curtains suspended from the ceiling and draped inside the arena walls. A wood collar supported a raised floor in the arena. This floor consisted of eight galvanized steel plates, divided into two parallel rows of four each, and the rows were separated by a wood divider. Each plate contained a 4 x 4 array of 4-cm drilled holes. Each hole was fitted with a cup that hung snugly from the cup’s rim. A plastic dish in the center of the divider acted as a feeder during cache sessions.
