The Slow Mo Guys captured this footage of the superhydrophobic surfaces scientists are working on at GE Global Research. These materials are being developed to keep ice off aviation equipment and wind turbines, and for self-cleaning applications.
This needs a soundtrack. The only one I have going in my head is “gluuuuurrp blooorrrrp sploosh”

The Leidenfrost Maze
If you’ve ever fried an egg, you’ve probably seen the Leidenfrost effect in action. When a liquid droplet is placed on a surface that is significantly above its boiling point, a layer of vapor is formed beneath the droplet, allowing it to skip and slide around like a deformed air hockey puck.
What I did not know is that grooved surfaces can guide those Leidenfloating droplets to go in a certain direction! So much so that University of bath researchers were able to guide the droplets through a maze using specially-arranged grooved hotplates.
Prepare to be wowed. This is one of the coolest science vids I’ve seen in a while.
Coincidentally, I think this is how the kitchen rats were able to skate on pats of butter in The Muppets Take Manhattan.
