Dry water
Dry water, an unusual form of "powdered liquid", is a water-air emulsion in which tiny water droplets, each the size of a grain of sand, are surrounded by a sandy silica coating. Dry water actually consists of 95% liquid water, but the silica coating prevents the water droplets from combining and turning back into a bulk liquid. The result is a white powder that looks very similar to table salt. It is also more commonly known among researchers as "empty water". == Discovery == Dry water was first patented in 1968 and was immediately snatched up by cosmetic companies as it appeared to have potential applications in the cosmetics field.〔 It was rediscovered in 2006 by the University of Hull, UK, and has since been evaluated and studied for its potential use in other fields.〔 The dry water itself is easy enough to manufacture. The hydrophobic silica nanoparticles and water are blended together using a motor with a stirring rod and impeller that spins at 19,000 rpm for 90 seconds, which coats the water droplets completely.
