Incredible slow motion footage shows drops of water spinning at 7,300 rpm

Daily Mail - Science & tech 

A mesmerising video shows the moment a water droplet bounces off a surface and is made to spin at more than 7,300 revolutions per minute (RPM). The properties of a droplet change depending on what it hits and scientists have manipulated this process to make them gyrate. Scientists say the findings could allow for future developments for hydro-energy collection, self-cleaning and anti-icing. Researchers from the Institute of Chemistry, part of the Chinese Academy of Sciences, say the observed process opens up a promising avenue for the delicate control of liquid motion. Huizeng Li and colleagues published the research in the journal Nature Communications and write in the abstract: 'Droplet impacting and bouncing off solid surface plays a vital role in various biological/ physiological processes and engineering applications.
