Abstract
A bubble making apparatus and method for producing an orderly chain of simply connected large bubbles. Bubble forming vents are provided into a bubble forming chamber at one end of a bubble forming tube. Bubbles propagate along the tube and are expelled through a bubble outlet port as a chain of bubbles with the aid of air flow through bubble propulsion vents. The chain of bubbles is supported by air flow from an air outlet port disposed below the bubble outlet port.
