Superhydrophobic Liquid Repellant Demonstration
Saw this on Junkee:
"“I am so sick of my T-shirt getting wet whenever I pour a lot of liquid on it!”
“I wish my iPhone 4 or 5 would not get so damaged every time I carefully place it at the bottom of a jug filled with water!”
“My new white shoes have been stained by the chocolate sauce and mustard I squeezed on them earlier! What gives?!”
“This cardboard box I chose to hold all of the water is just not doing a great job of it! ”
These are all things you’re used to saying, but you will be saying them no longer! After a two year wait, Rust-Oleum’s NeverWet – an invention of Ross Nanotechnology (great business name, Ross) – has just hit shelves in the States.
It is “a family of super hydrophobic coating that completely repels water and heavy oils,” and you can buy it online here for $20 a can."

"Couple questions left unanswered:
A) What does it taste like?
B) What does it feel like?
C) How much cancer will it give me, and how quickly?
D) What happens if you get it on your hands and then you want to wash it off your hands? Will you be NeverWet forever?
5) If you spray the inside walls of a glass tumbler with NeverWet but not the inside base of that tumbler, and then you fill up the tumbler with water or with another liquid of your choice, like mustard, will it form a mustard tower inside the tumbler? Can you take a photo of the mustard tower and send it to us very soon?"
18 Things That Actually Exist
The non-wetting plunger (assume a nano molecular hydrophobic surface is the trick) actually makes a lot of sense---no drips when you lift over the edge of the bowl after using...More hygenic?

when it's poured into the water... it looked like red poop. eeeeeeeeeewwwwwwwwwww
No kidding. I was eating my late lunch!!

Spray on Superhydrophobic Coatings
Some things need hydration to maintain their structural form over the long term, so don't go to crazy with hydrophobic applications...can lead to cracking and embrittlement of certain materials.

MIT Team Create Ketchup Bottle That Pours Like Water
I'd bet it's been coated with the new "hydrophobic" surface coating. Expect it to be on everything soon.

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

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.

NeverWet Spray Makes Any Fabric 100% Water Proof
"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?
NeverWet Spray Makes Any Fabric 100% Water Proof
Probably quicker, more fuel-efficient and very bad for the environment. >> ^Drachen_Jager:

WTF? Mind-blowing Condiment Picker Upper
I call bullshit on something here. Its either not a real condiment, and some substitute that is hydrophobic to the material its both sitting on, and that the machine has.....or its...ITS BLACK MAGIC, BURN THEM!!
Water Droplet Bouncing on a Superhydrophobic Nanotube Array
I didn't realize things could be SUPERhydrophobic, I thought they were just hydrophobic. Hurry up nanotubes, make me a damn space elevator already
I also would like to see these tests at regular speed
