The needles rest, like a layer of grass, on a surface of Teflon. When water hits the material, it encounters air trapped in the spaces between the needles. And this makes the fabric extraordinarily slippery — 99 % much less sticky than a traditional Teflon floor without the nano-sized needles [supply: BBC Information].
