Individual bubbles ca. 2.5 mm in diameter were produced at a capillary in water containing frother, polymer or inorganic salt. Bubble aspect ratio (shape) and rise velocity were measured ca. 1.2 m above the point of generation. Results suggest a unique relationship between bubble shape and rise velocity which is independent of solute type or concentration.
