  • Bubble blowing apparatus
    Patent number: 5542869
    Abstract: A bubble blowing apparatus for the automatic, self-generation of bubbles in moving air such as a wind or breeze. Such movement of ambient air causes a fan assembly to rotate which, in turn, imparts rotational movement to a bubble-wand assembly. The relationship between the fan assembly and bubble-wand assembly is such that the energy taken out of the moving air by the fan assembly improves the bubble formation characteristics of the bubble-wand assembly.
