Conceptual artist Martin John Callanan has a thing for puzzles. He spent one whole day working on a five-pound misprinted note that was destroyed by the Bank of England. The objective? Put it back together.

His incredible 11-minute time-lapse video demonstrates his remarkable patience and determination as he slowly worked on the shredded currency note. First, though, he had to get in touch with the Bank of England to get hold of out-of-circulation shredded cash.

He used tweezers to work slowly, reassembling the pieces painstakingly. The final result, of course, only loosely resembles the original note, but it’s worth noting that he did succeed in getting all the bits and pieces in the right places.

An impressed viewer commented, “This is a beautiful piece of art. Thank you for contributing this to the world.”
