In July 2015 we set up a new book domino world record with 6,631 books. We organized this project and realized it together with students of the University of Bozen. The setup took 3 days in total and the falldown was over 5 minutes long.
The books were spread over 4 floors in the library of the University and were mostly built on a carpeted floor. Only books that were not needed anymore were used for the record. 6,620 of 6,631 books toppled in total: A new World Record!
