Walls of expo structure to be made of water

July 16, 2007


Walking through walls will be possible and even encouraged.

When next year's world expo opens in Zaragoza, Spain, fairgoers will encounter a building with walls made of thin sprays of water. Inside, there will be normal building stuff: a cafe, an exhibition space and overhead lighting.

The water will come from thousands of little jets that can be switched on and off, rapid-fire, by computer-controlled sensors. As a person approaches, the sensors could shape the water flow to make a door appear anywhere in the wall and then close it.

The Massachusetts Institute of Technology architects who developed the idea say it's a boundary-pushing artistic statement, in the tradition of the Crystal Palace and White City of long-ago world's fairs. Current estimated cost is about $3 million.

The theme of the Zaragoza fair is water and sustainable development.
