UnWettable: Water on a Bed of Nails

As I have confessed freely on these pages over the (13) blog-years, I am easily delighted and amused, and also perplexed for that matter.

So in the details of bejeweled beading water drops on the local plant life I have previously expounded and gushed effusive. See More reading below.

Add to that delight a little science. Watch water drops bounce and either splatter into a shower of tiny round beads or coalesce into larger super-drops on an “unwettable” leaf surface. Why is that?

It is because the leaf is designed so that the water does not actually touch the leaf but rides on a “bed of nails” created by the leaf cuticle micro-structure.

Watch the three short videos at the following link. Then sit out in the rain and take in the dance of raindrops. The finest of details your eyes cannot see create diamond unwetness around you.
