Have you heard of the seven-meter boat of 160,000 wine corks? The vessel weighing 1600 kg was built by John Pollack, known among other things for the fact that 30 years he was picking up corks and was a speechwriter with US President Bill Clinton . Having swam on their wonder-boat 265 kilometers on the Portuguese Douro River, Pollack got the nickname “Captain cork”.

John, said to the reporters that he understood the “senselessness of the event he started”, but some of his nature “wants to continue playing kid’s games.”

In principle, such a boat is not an ordinary eccentricity: a cork has long been used in seaworthy business, because on the water it holds weight many times higher than its own, and almost does not absorb moisture. For the produce of life-saving craft it is generally indispensable.
