•Bubbles ca. 2.5 mm in diameter were produced at a capillary.•Frother, polymer or inorganic salt solutions tested.•Bubble aspect ratio (shape) and velocity were measured.•Unique bubble shape–velocity relationship was found.•Relationship independent of solute type and concentration.
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.
