A two-component liquid drop is generated over a hole on a superhydrophobic substrate. When a 6 V electrolysis voltage was applied to the overhanging component of the liquid drop, bubbles of oxygen and hydrogen at rates of 0.0025 and 0.045 mm3/s respectively were produced. Positioning the electrode beneath the hole allowed the gas bubbles to travel upwards by buoyancy into the overhead liquid component for aeration. The bubbles broke-up into smaller sizes, which would facilitate gas diffusion to the liquid phase, and populated the apex of the overhead component.
