One example I use when discussing consumer benefits of nano-technology, are that of nano-materials. I've explained to my partner about clothes made
from nano-materials, how they will never get wet, or dirty, because the fibres are too small for the dirt and water particles to stick to.
I found this video, which is an amazing example. The suit that they use has only been nano-treated though, so the effect is not 100% as effective as
nano-spun fibre. Enjoy
