Short video at the link here demoing an new coating that can be put on just about anything. You’ve maybe seen hydrophobic coatings that make water bead up on something and not be absorbed? This does that with water and oil, which are basically the two main solvents that get onto things and make them dirty. I could see this being put just about anywhere. Neat stuff! (More reasons I went into engineering, to be part of stuff like this at some point.)
Hydrophobic, dirt-shedding spray is indistinguishable from magic – Boing Boing.
