Step aside, Teflon. Physicists at the University of Rochester have found a way to make metal so resistant to water that any droplets that fall on it simply bounce off like tiny basketballs.
Apart from being freaky to watch in action, the first-of-its kind material may have important applications--from making better devices for collecting rainwater in water-scarce developing countries, to improving the sanitation of toilets, to making airplane wings and solar panels resistant to rusting or icing over.
