Disclosed embodiments include a bubble generating apparatus (100) operable to generate bubbles from a bubble generating liquid. In an exemplary embodiment, the exemplary bubble generating apparatus includes a symmetric output assembly (11) having a bubble formation surface (11d) and a central opening (11e) defined therethrough. A liquid film may be formed across the central opening of the bubble formation surface, and air flow may be provided through the central opening of the bubble formation surface to generate bubbles from the liquid film. |
