Hydrophobic Water Droplets

This might be the most beautiful video I've ever watched which is also helped me understand physics a little bit better. This guy's whole site Smarter Every Day is absolutely fantastic. He specializes in using state of the art camera equipment and filming techniques to capture the world as it exists at speeds and resolutions we simply have never had access to before. 

This video also reminds me of another one of my favorites of all time.
