Is powdered water the cure for drought and famine? Engineers create material capable of storing water in soil for a YEAR

Solid Rain is made of a material called potassium polyacrylate

This polymer can absorb water up to 500 times its size

Water is retained in the polymer for a year and can be added to plant soil



Farmers in arid countries could soon have a cure for the droughts that blight their crops - in the form of powdered water.



The powder, called Solid Rain, looks like sugar and is made of an absorbent material called potassium polyacrylate, capable of soaking in liquids up to 500 times its size.



The water absorbed by the polymer can be stored for up to a year without evaporating - the only time it is extracted is when it is by the roots of plants when the can be added to soils to produce water for plants.

WHAT IS SOLID RAIN?

Solid Rain is an absorbent polymer called potassium polyacrylate.

This polymer is capable of soaking in water up to 500 times its original size. A whole litre of water can be absorbed in just 10 grams of Solid Rain, which then converts into a thick, translucent gel.

The liquid retained by the polymer will stay there for a year without evaporating or seeping out.

It can only be extracted when its added to soil and comes into contact with the roots of plants.

Solid Rain was created by Mexican chemical engineer Sergio Jésus Rico Velasco.

He initially wanted to find an absorbent material that could be used in nappies to absorb lots of liquid in a small space.



Velasco later realised that his potassium-based polymer could be used as a way to cure Mexico's drought problems.
