Urban Water Needs: Can we keep up? (Matthew Laws and Hal Watts)
Combining their engineer’s precision with creativity honed at the London Royal College of Art, Matt and Hal first designed a world map entirely out of cheap kitchen sponges. They then poured water onto each country in amounts proportional to that its expected urban water consumption in 2030. Elegantly literal, the sponges grow in height according to how thirsty the country will be, generating a stark topography of future needs for urban domestic water.
