Have you seen water bounce?



The first few secs shows wat a normal water droplet does when it strikes a normal surface, until the part where it bounces up. It normally breaks up to even smaller droplets and stick to the surface.

The whole video shows how the water droplet reacts when it drops on a super hydrophobic(Freaking afraid of water, water repelling) surface, created by GE's Global Research Nanotechnology lab. Boy, these guys super free.

Cool hur? Heres what those research guys say.

Hello everyone, I have some exciting videos that I want to share with you! Using a high-speed camera setup in the lab, we can finally capture the details of the water dancing on these amazing superhydrophobic surfaces. We discovered that even when the surfaces had the same contact angle for stationary water droplets, their ability to resist the wetting of impacting droplets could be totally different. In the following three videos, the contact angles of a stationary droplet on all three surfaces are ~150 degree. When an impacting droplet (with the same impact speed) hits on the surfaces, the droplet can either stay on the surface.

Look at the way the water droplet spreads, recoils, breaks into satellite droplets, and completely lifts off... that's what we really want for an impacting-droplet resistant surface! You might wonder what we can do with a cool thing like this? Imagine applications that involve high speed water droplets, such as wind turbine blade, airplane wing, or even just your car in motion. These are just a couple of the exciting possibilities that we are looking at.

Can they coat this on motorcycle helmet's visor? Rain always give me problems.

Caught this on Gizmodo, hahaha should see the comments section. How diff people commented water already bounces when raining or showering. Interesting to see ppl dont really think much before posting comments.
