Our local art museum just held its Seventh Annual Domino Toppling Extravaganza (to offer up its official name) with (mostly) children and parents crowding in to witness 29,440 dominoes going kerplunk. Not counting the time to design the whole thing, it took something like four "domino whiz kid" teens forty hours to set everything up. And I'd say maybe five minutes for it to collapse after a ball was dropped down a mini-tower setting off the chain reaction.
To insure against the disaster of a premature topple, several dominoes throughout the entire set up were put aside until just before the signal was given for the toppling to begin. As you view these pictures, then, you'll notice that some of the lines are broken. But, be assured, at Topple Time, everything was back in place.

|Everything is going fast.|
We were told that this may have been a record number of dominoes toppled in the U.S. though some countries, especially the Netherlands, go in for ten times that number.
