Like tear drops water assembles on the leaf
and stays until they almost burst.
Tears trickle down the face in silent grief
after they wet the blinking eyes at first.
The surface of the leaf, however,
repels the water so that it stays dry.
When engineers found this extremely clever
they thought this technically was the latest cry.
Nano particles keep water off the leaves,
so why not use them as a water shield?
But now we know the problem that this leaves,
which is a largely unexplored new field.
These particles are held back by no barrier,
in our body they pass each membrane,
which makes extensive use of them the scarier
the more they are employed. This is insane!
