What happens when you pour red food coloring into a geyser? Last spring, Chilean-born Danish artist Marco Evaristti (MAR-koh EH-fah-ree-stee) found out. The artist poured more than a gallon of red fruit-based dye into an active geyser in Iceland. The hot spring erupted bright-pink water and steam. This was the fifth time the artist has dyed a natural landscape pink as part of a series of works called Pink State.
