Well this is something you certainly don't see every day. It's a tiny droplet of alcohol that's autonomously navigating a maze in an effort to reach a target. The researchers who set up the experiment say it could lead to some interesting new technologies.
There are a lot of great applications for materials being developed that display extreme water repelling properties, inspired by nature and particularly desert life. This video doesn't explain any of them and that's fine—I just like to watch all those crazy water droplets doing crazy stuff.
Scientists at Rensselaer Polytechnic Institute have come up with this freaky adaptive liquid-lens that can capture 250 in-focus images per second. It's essentially droplets of water in a pair, trapped in chamber and driven by a high-frequency sound wave to oscillate.As the drops wiggle back and forth, surface tension…
