Abstract: A javelin for practice throwing indoors having drag inducing members adjacent its ends which react with the air-stream to limit the javelin''s travel. The drag inducing members are preferably of conical shape, apertured to provide the drag desired without causing unstability of the javelin in flight. The javelin additionally includes a blunt resilient impact member at the javelin''s forward end to prevent damage to floor or wall surfaces.
