'Dry water' set to make big splash

IT sounds like a contradiction in terms, but scientists have created "dry water".

The substance resembles powdered sugar and is expected to make a big commercial splash. Each particle of dry water contains a water droplet surrounded by a sandy silica coating. In fact, 95pc of dry water is "wet" water.

One of its key properties is a powerful ability to absorb gases. Scientists believe dry water could be used to combat global warming by soaking up and trapping the greenhouse gas carbon dioxide. Tests show it is more than three times better at absorbing carbon dioxide than ordinary water.

The technology could be adapted to create "dry" powder emulsions that could make it safer to store and transport potentially harmful liquids, the 240th National Meeting of the American Chemical Society in Boston heard.
