From milk cartons to seafaring vessels, are there no limits to the wonders of Tetrapak? In August 2007, German artist Frank Bölter used origami paper-folding techniques to build a nine-metre-long boat made of Tetrapak - the heavyweight paper usually used to package milk or juice.
Bölter's original plan was to sail the unpowered, sail-less boat along the River Elbe from Lauenburg (50 kilometres north of Hamburg) until he reached the North Sea. Unfortunately, he'd forgotten to apply for a permit from the shipping office. The boat's sole mission was consequently limited to a short cruise around Lauenburg harbour.
