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.
Watch the video from Thoisoi2 – Chemical Experiments! where he experiments with dry water. The result is a white powder that looks very similar to table salt. It is also more commonly known among researchers as empty water.
It has also been theorized that dry water could have potential uses in the construction of fuel cells for automobiles due to its ability to store and stabilize very large amounts of volatile gases and materials without permanently binding them.Due to its nature, dry water is classified as an adsorbent material. It has many potential uses in fields where emulsions are required or used.//via/read more: Wikipedia
