Nano-technology is amazing. After watching this video, I think I love the spray on clothing the most!
A) Ultra-ever dry (0:00-4:03)
Sprays on anything to protect it from being damaged by accidental water, oil, mud and even concrete spillage.
B) Spray on material (see minute 4:05).
The material can be washed and worn again, but it can also be dissolved to create a new clothing.
C) Liquipel (5:33)
Protects cellular phones from accidental water damage.
