High-speed Video of Water Droplets

Thanks to Chris K.:

Hydrophobic materials have very interesting and sometimes beautiful effects on water. Water bounces off, and depending on the impact velocity will break into smaller pieces, still in ball forms of course. The water droplet balls bounce and even roll down curved or angles surfaces as would be expected. Most interestingly the balls can combine with each other seemingly well if they hit each other going opposite directions.

This video was made using a high-speed camera, using various frame rates. The super hydrophobic material was made with a carbon nanotube array and microliter sized droplets.
