Damn near everything is water-resistant, but water-repellant is quickly replacing it as top dog in the crusade to avoid water at all costs. A new structure featured in Nature, a scientific journal, keeps whatever it conceals dry by bouncing water off its surface and cutting it before it goes. It basically punishes water for even thinking of finding purchase on your valuables.
The structure works by using ridges that are .1mm, known by Americans as 1/250th, of an inch high. Water hits the ridges and splits before bouncing away. According to Kripa Varanasi, an MIT scientist, this method reduces the overall amount of time water touches the surface by 37% compared to the water-repellant material that’s in use now.
The video taught me quite a bit about water-repellence in nature and its potential uses. It’s pretty interesting and worth a look – the video is only two minutes long.
Although, while the scientists think of all the super scientific ways water-repellence can be put to use, just think about how amazing that material would be if it were used to create a waterproof case for your phone! You’d never have to worry about getting caught in the rain or being shoved into a pool again! (Yes, it happens…)
