The skin of a gecko isn't just creepy to touch, it's also weird to watch.In this slow-motion video produced by New Scientist, a gecko's skin rivals the water-resistance of an expensive North Face jacket. As the clip explains, the skin is comprised of a sheet of "spinules," a porous surface that helps them shed water.So when a lot of water amass on the skin, the spinules react by launching the water off like its the inside of a lottery ball machine. Sometimes the droplets repel completely off the body, and other times the droplets fall back on the skin which causes other droplets to launch off."The phenomenon has been seen previously on some insects and artificial surfaces, but never on geckos," notes New Scientist.Australian researchers call it "geckovescence" and are mulling a few theories of why it occurs on geckos. The video explains that it might be a self-cleaning mechanism to remove bacteria from those hard-to-reach places, or that this activity has evolved so microbes don't form on the skin.
