Abstract
A sounding toy has a sounding member body that defines a plurality of circumferentially spaced internal cavities (12), each of which is enclosed except for a side opening (10) communicating therewith. A pair of flexible cords (30) extend axially through a center portion of the body (2). The cavities (12) and side openings (10) are configured to produce a whistling sound when the sounding member (2) is caused to rotate by winding and then tightening the cords (30). The geometry of the body (2) is chosen to force air into the cavities (12) when the body (2) is rotating in either direction about its axis.
