Agricultural wonder can expand to 500 times it's original size and store water for up to a year.

Solid Rain is a Mexican-made product that looks like salt and sells for $25 a pound. It's makers claim that the product is capable of solving the world's drought problems.

The product's creator is a chemical engineer by the name of Sergio Jésus Rico Velasco, a man who's spent decades trying to mitigate the drought problems that Mexico suffers from.

Inspired by baby diapers – Solid Rain is actually a highly absorbent polymer called potassium polyacrylate, which soaks in water up to 500 times its original size. 10 grams is all it takes to soak up a litre of water, transforming it into a thick, translucent gel.
