    Patent number: 6231414
    Abstract: The invention relates to a toy, for example a Frisbee-type disc, a toy aircraft, a toy gplf club or a toy baton, provided with means for generating a stream of bubbles in use. The toy is constructed with a liquid reservoir which feeds liquid through a narrow gap to holes formed in overlying superimposed planar members. At these holes the liquid, which is a bubble-forming liquid such as a soap solution, forms a thin film until a bubble is formed under the influence of the airstreams generated around the holes as the toy moves in the air.
