the best dominos fall world record

I’ve never really understood how to play dominos – so we’d get them to do line them up, push one and watch them fall!

I’m not the greatest at balancing yet alone stand up a row of pieces to knock one over and watch them all fall.  Even my kids get frustrated when they get a line up and one just happens to fall and within seconds the whole thing is over!

Below is a video that won a world record!  It took 7 full minutes to knock them all down!  So….how long did it take them to set this all up???
