 This study examined how quickly droplets can be removed from a rotating surface. It found that the droplets detach much faster than expected, forming a doughnut shape before scattering away. This phenomenon was attributed to the combination of the rotational motion and the droplets own momentum. This discovery could lead to new ways to reduce the amount of time it takes for liquids to dry or clean up after themselves. This article was authored by Rand Tao, Wei Fong, Jun Wu, and others.
