Videos #3, #4, and #5 show three capillary droplets in three micro-ratchets with different aspect ratios, corresponding to the micro-ratchets A, B, and in Figures In video #6, capillary droplet successfully climbs tilted micro-ratchet, however the drop falls back again when it reaches the end of the ratchet-patterned area.
