For those of you interested in the actual mechanics of the superhydrophobicity, I direct you to this wiki:

http://en.wikipedia.org/wiki/Lotus_effect

Basically, the reason its so repellent isn't due to a hydrophobic coating, but rather the development of a surface nanostructure that has sharp angles and points in such a way that the surface tension of water binding to the surface is less than the attraction of the dipoles of the water molecule to other water molecules. As a result of this, the water forms globules on the surface rather than running off the side.

It's easier to type WITCHCRAFT! Also acceptable: SORCERY!

"Water and heavy oils will just shoot off of it" Guh? Shouldn't this stuff be attracted to oil if it's hydrophobic? Or did he just mean that it repels emulations like the chocolate sauce?

This would make for some hiLARious Kleenex and toilet paper.

Or on the helpful side you just coat your butt with it. Drop n Go, no mess, no paper.
You thought explosive diarrhea was bad? Wait until you experience super-hydrophobic explosive diarrhea

Wonder what this would do for you on a wetsuit...


Not sure, you'd probably be able to swim faster (less drag). Don't know if you'd experience the same level of bouyancy as a non treated wetsuit, although I suspect so. I think bouyancy is related to the weight/density of the object displacing water rather than surface tension holding it aloft ala water spiders.

Don't forget the ever popular "God did it", Jesus probably coated his feet with this shit.

Best not to hope. The a-holes at "Rain X" could cut a fat check to these nerds and shelve this stuff another 10 years.

Currently, commercial availability only. Retail products by mid-2012.

It wouldn't be the first time, but I think the potential upside is much larger than Rain-X could afford.
