Superhydrophobic Liquid Repellant Demonstration

Trancecoach says...

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?

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.

WTF? Mind-blowing Condiment Picker Upper

charliem says...

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!!

residue says...

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
