> 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.[1] 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.[2] The result is a white powder that looks very similar to table salt. It is also more commonly known among researchers as empty water. ~ https://www.wikiwand.com/en/Dry_water
