Why do you use materials from nature such as soil, moss, and water?

Olafur Eliasson: "I don't think the materials have specific qualities themselves. They don't have an intrinsic value. But when I bring moss into a museum or make water run upwards or produce artificial mist, I can get people to reflect on these phenomena. I take the natural materials and displace them into the museum context. I think it's really important to realize that nature isn't just out there, it isn't "natural"—it's always organized by our individual perspective."

Eliasson describes how everyone sees a different rainbow
