By comparing the hydrophobic surface and nanotextured surface, the group discovered that enhanced
water droplet bouncing was created by the combined impact of the Leidenfrost levitation and the nonwetting Cassie state.
And
the water droplet bouncing was powered by the synergetic combination of the nonwetting surface — often called a «Cassie surface» — and the Leidenfrost effect.»

But because the scales tilt about 30 degrees upwards from the wing surface, they act like springs,
bouncing away
water droplets that land on them.
In a new twist, a group of South Korean researchers from Seoul National University and Dankook University report an anomalous
water droplet -
bouncing phenomenon generated by Leidenfrost levitation on nanotextured surfaces in Applied Physics Letters, from AIP Publishing.
All the materials became waterproof and self - cleaning as
water droplets of different sizes were seen
bouncing instead of wetting the surface, removing the dirt applied by the researchers.
Water droplets will
bounce up, form spheres and scurry across the surface.
Bouncing water droplets can get higher with every hop — weird enough for you?
Water, oil, and lava
droplets fall from â $ œdroppersâ $ and will
bounce around the walls of a puzzle.
Similar principle to how clouds form: if a molecule of
water vapor hits a
water droplet it has an excellent chance of sticking to it instead of
bouncing off it.
