NeverWet Spray makes nearly any surface superhydrophobic, causing liquids to slide right off.

Ross Nanotechnology has developed a silicon spray, NeverWet, that can make electronics, clothing and nearly any other surface extremely waterproof.

The product is superhydrophobic, which means it repels liquids at a very high ‘contact angle,’ the measured distance between a liquid droplet and a surface. The higher the angle, the rounder the droplet. Surfaces treated with NeverWet have a contact angle of 175 degrees, while Teflon and car wax are between 90-95 degrees.
