Nano technology and Hydrophobic

I was getting ready to write another experiment in the blog when my hubby dear sent me this video to watch.  Its just so cool that I decided to write about this instead.

Nano technology and Nano science are relatively new fields and there is a lot to learn but are also very fascinating subjects.  To get an idea about the scale of Nano-technology, imagine this:  a single human hair is approximately 80,000 - 100,000 nanometers wide!!!  So, we are talking about how things can be manipulated at that minute scale.

A company called UltraTech came up with a new product called Ultra-Ever Dry..A liquid/spray that can be sprayed on almost any surface (or they claim) and it will repel water, oils, atleast limited number of acids!!!.  Imagine a car coated with this would never need a wash again:)

Here's a cool video of how the product works.  Wish I could get more info as to how it works but ofcourse it would be their secret not to share right...The only info I could find is that the nano-coating relies on a barrier of oxygen/air to form the barrier on the surface of the material it is coating.  Meaning the surface does need to be exposed to air (and so cant be used inside a pipe which is under the ground?).

Here's a video that shows how it works....
