Abstract
A bubble-blowing apparatus that may simultaneously produce a plurality of bubble streams from liquid bubble solution is provided with a housing, a rotatable fan associated with the housing, an electric motor operatively coupled to rotatably drive the fan, a battery power source coupled to provide electric power to the motor, an airflow-directing member coupled to the housing that causes air blown by rotation of the fan to be directed predominantly to a peripheral area, and a plurality of bubble-forming tubes operatively coupled to the airflow-directing member at a plurality of points in the peripheral area. Each of the bubble-forming tubes is capable of generating a stream of bubbles and may include a hollow central portion, a base portion, and an end portion that is spaced from the base portion by a distance in a direction parallel to the central diameters of the bubble-forming tubes.
