A Chilean artist has been jailed after dyeing a famous hot spring in Iceland pink with food colouring. Marco
Evaristti, the South American artist who is based in Copenhagen, poured
red fruit dye into the Strokkur Geysir, found around 70 miles to the
north east of Reykjavik, at dawn.When
they boiled, vibrant pink steam blew up from the ground as a result.
Professing that ‘nature belongs to no one’, he did not seek permission
from local authorities before the stunt. He has since been jailed for two weeks after landowners lambasted his efforts as ‘vandalism’
