Superhydrophobic carbon nanotube water droplet bouncing GIF goodness.
by David Ng
“Superhydrophobic surfaces are those which repel water to such a degree that droplets roll right off. The forces of surface tension actually overtake the friction of the surface the droplet rests on, and this is what keep the droplets from wetting.”
