This student in Bristol, southwest England, managed to complete a 4,000 piece puzzle and recorded the whole 48 hours and five-minute build.
The student, known as Puzzlesbynathan on social media, reveals the best way to do a puzzle is by separating each section into their own pots and going one pot at a time.

"This took a whopping 48 hours and 5 minutes to complete, but we get to relive it all at over 800 times the speed in order to get a very oddly satisfying effect," the filmer told Newsflare.
