Fundamentals
Sticky and highly viscous liquids
Sticky and highly viscous liquids on evolutionary optimized surfaces (e.g. the sacred lotus) superhydrophobicity reaches as far as not even to allow honey or water-soluble liquid glue to stick to their surface, but to completely roll off the leaf.
Figure 1: Not even water-soluble viscous glue will stick to the surface, but rolls off the leaf of the Lotus flower.
Figure 2: Even highly viscous liquids like honey roll off from the anti adhesive surface of this spoon.
