This awesome video of books collapsing has set a world record for longest domino chain - and it's all for the good cause of encouraging kids to read.

Concept designers Luke Greenway and Laura D'Asaro assembled lines of books that traverse stacks, climb stairs, and even spell out the word "read."
Not only that, the tumbling works encircle a number of library patrons in action! Take a look at the awesome, literary domino chain collapse below:
