Abstract
A multiple bladed clapper-noisemaker is provided with a stiff central blade and adjacent thinner blades of flexible sheet material whose lower ends are held in closely juxtaposed stacked relationship by the user and whose upper ends are free to flex and bend as the user imparts flapping movement to the device. The flexible outer blades rhythmically swing away from the stiff central 'drum' blade and swing back to strike it briskly with a sharp impact. The multiple impacts of the plurality of flexible blades are employed by the user to create a wide variety of different sounds, ranging from soft brushing or rattling sounds to louder multiple clapping sounds of all varieties. When the handle portions are secured together by a single grommet fastener, the multiple blades may be fanned out angularly to form an air displacing fan or an attractive decoration for horizontal or suspended display.
