Paper Boat...is it art?

An "artist" in Germany named Frank Boelter has built a boat of the that 'Tetrapack' stuff that they use to make milk cartons.
He "came up with the idea one breakfast time, while he was sitting at his kitchen table fiddling with an empty milk carton, which he cut up and made into a scaled-down model."

The boat is 30 feet long, weighs 55 pounds, uses a 170-square-metre piece of Tetrapack paper, and took only two hours to construct. The "artist" said it will survive forty days before it disintegrates into a wet, sinking mass.

It is part of his exhibition named 'Bis ans Ende der Welt' (Until the end of the world).
