HzO has invented a nanotechnology that coats the inside of electronics, making them impervious to water. I have pulled useless electronics out of toilets, the garden after a rainstorm, a bathtub, and the rinse cycle in the washing machine. There are cases that will do this but they never seem to be on the phone when it takes a spill. So I’m adding this to my feature checklist next time I buy a cell phone.
