Watch a giant domino tower fall after 7 hours of building with 3,242 dominoes

Epic fail.

What is described as “America’s largest domino tower” collapses on camera, after 7 straight hours of building.

The builders stacked 3,242 dominoes in 241 layers on a 19-foot-tall freestanding tower, some 10 layers away from being the second tallest tower in the world when it randomly collapsed.
