Slow water I was presented with the question 'how to slow water down between the sky and the sea?'  My approach was to make the effect of water visible. Our homes are modern marvels of hydrophobic materials. Steel pipes and ceramic basins bring water to us and carry it away without leaving a mark. What if out kitchens and bathrooms were eroding as well? I have made a sink entirely out of soap. the more you use it, the more it dissolves and washes away. Materials: soap, steel, wood
