Abstract: Apparatus for producing from a bubble solution a beard of long, interconnected bubble chains comprises a hollow elongate tube having opposite ends and a sidewall connecting the opposite ends. The tube has at one end a first portion adapted to receive a gas and at the opposite end a second portion defining at least one aperture extending through the sidewall and in gaseous communication with the first portion. A porous cloth is disposed over and about each of the apertures, the cloth defining a multiplicity of substantially minute interstices for holding thin films of bubble solution. Gas introduced at the one tube end passes through the first tube portion, into the second tube portion, and emerges from the apertures through the bubble solution held in the cloth to form a beard of bubbles extending about and along substantially the entire length of the second portion sidewall.
