Sans prévenir, il déverse une poudre de pigment de couleur rouge depuis un des nombreux ponts de la ville. Une eau verte envahi alors la ville.
Olafur Eliasson:
" At the time I was working on a smaller project, but very quickly the idea of colouring downtown Stockholm became something I just had to do. I bought the pigment in Germany and came back through customs with a real feeling ofsuspense and excitement; after all, I had enough colorant with me to dye the whole centre of the city. This wasn't an official project; I had to work really fast, so I'd gotthe planning down pat together with the current and the turbulence in the river, and one Friday at half past one there I was on the bridge with Emile and a bag full of red powder and people starting to stare at us. I hesitated for a moment then emptied the bag out over the parapet and the wind whipped up this enormous red cloud. I couldliterally feel people in cars slowing down, the cars went all quiet. And there was this cloud, floating over the river like a layer of gas. When it came in contact with thewater, all of a sudden the river turned green, it was like a shock wave. There was a crowded bus ten metres a way and everybody was staring at the water. I told Emile weshould maybe move on, as if everything was perfectly normal, then I carefully put the bag in a trashcan, as if colouring the centre of Stockholm was the kind of thing I didevery day. I went down to IASPIS and when I came out again my heart started jumping up and down like mad: the whole length of the river was completely greenand all these people had stopped to look at it. Next day it was all over the front page of the papers: "The river turned green". The colorant was absolutely harmless and therewas no pollution whatsoever. "
