'Just Add Water' Instant Shelters

Emergency shelterAn emergency shelter which can be set up in 40 minutes as a solid concrete structure will be made in south Wales after winning worldwide interest.

The shelter is delivered in a bag, which is ripped open and water added.

The material soaks up the moisture, activating the concrete. But the cloth remains flexible and is inflated by a battery-operated pump.

After 12 hours, the shelter becomes completely solid, and can even withstand being shot at with handguns.

Will Crawford and Peter Brewin's design will go into production at their new plant near Pontypridd next summer.
