Seattle Public Library just set an unusual world record in its incredible flagship building: the world's longest book domino chain.
Created to launch its summer reading program, 2,131 books were used in the service of this magical video that you can watch above, filmed on May 31st. Our favorite part? The silent summer readers sitting among the books as they quietly fell around them.
Just don't try this at home kids, unless you're prepared to pick them all up afterwards.
