To kickoff its Summer Reading Program, the Seattle Public Library aligned some 2,131 hardcover books across floors and bookshelves before toppling them over in classic domino fashion.
The stunt took place on the third floor of the Rem Koolhaas-designed Seattle Central Library, where 27 volunteers committed their steady hands to seven hours of setup, resulting in the world's longest book domino chain. The effort was done to promote "Expand Your Horizons," the theme for the Library's Summer Reading Program.
"We had to be packed up and out of the building by midnight," said Amy Twito, the Library's youth program manager. "Everyone was so happy that we were able to break the record."
It took four previous tries before finally getting the smooth and record-breaking topple. The books used in the stunt were either donated or out-of-date. The nonprofit Friends of The Seattle Library plans to sell the books to raise money for library programs.
