Water Droplet Bounces Off a Superhydrophobic Nanotube Array
These drops of water are pretty amazing (and lovely) in slow motion. Perhaps Ludwig will come along and explain what other forces might be at work besides gravity & velocity. Friction maybe?
Hydrophobic materials have all kinds of practical applications, from creating surfaces that never have to be cleaned to making supertankers and container ships glide more efficiently through the water. But practical applications aside, this amazing video — showing the crazy, beautifu; ways water droplets interact with a carbon nanotube array —might be mistaken for art rather than science.
