Figure 1. Schematic of a spinning levitating drop inside the magnet bore as viewed from i) the side, ii) above (camera view).

Direction of air flow is indicated by white arrows. Solid black arrows show the direction of rotation. Magnetic field lines are drawn in red. iii) Evolution of the droplet shape (schematic) with increasing angular velocity. The three symmetry axes are labelled a, b and c, where a is the longest axis, c coincides with the axis of rotation, and b is perpendicular to a and c.
