Question

Why does water trickle off lotus leaves?

Answer 1

Some plant leaves just can't get wet or dirty! Lotus plants have superhydrophobic surfaces. Water drops that fall onto them bead up and roll off. These leaves not only stay dry, but the droplets pick up small particles of dirt as they roll, so that the lotus leaves are even self-cleaning.

Answer 2

The lotus leaves are known to have a wax-like coating on the surface which acts as a waterproof layer or coating.

• When the water falls on the surface of lotus leaves, it trickles down and falls off the leaves.
• This wax-like surface can also regenerate itself.
• This waterproof surface is known as a superhydrophic surface.
• This not only helps the leaves to stay dry but also keeps the surface clean as the water while falling off, cleans the dirt off of the surface.
