Summer, sweltering temperatures, sunshine, and …refreshing mist? This unlikely mixture was recently staged by the Effektschmiede on the square in front of the science centre phaeno in Wolfsburg, Germany. In intervals of half an hour, the four beds of reeds surrounded by seating areas that reach out of the minimalistic, grey square are enveloped in manmade, water-based fog – we do not rely on artificial, chemical fog. The environs are thereby turned into climatic microcosms of their own: the temperatures go down and humidity-levels rise.
