Abstract: A fishing lure comprises an elongate body of flexible plastics material having an internal sound producing device comprising at least one chamber of small dimensions containing a single ball. The relative dimensions of the ball and cavity are such that the ball is constrained against rattling against the walls of the cavity with movement of the lure and instead is guided to follow a rolling movement around the walls of the cavity, producing a sound frequency attractive to fish. The chamber is provided in a suitable lightweight plastics material capsule embedded in the lure body, and may be of circular dome or annular shape.
