Scientists use lasers to make metals super water-repellent Video Description

The unique properties of superhydrophobic surfaces could have all sorts of real-world benefits, making surfaces easier to clean (water droplets just pick up dust and roll away) and less corrosive. Guo says that one application would be in developing countries where water is scarce. "In these regions, collecting rainwater is vital and using super-hydrophobic materials could increase the efficiency," he says. "A second application could be creating latrines that are cleaner and healthier to use."
