There are a lot of domino toppling efforts out there that are always amazing to watch. This one is up there with the best. Domino toppling done on four pool tables! The guy shoots a pool ball and then the dominoes begin to fall one by one and thus pushing the other balls into the various holes of the table. And after the dominoes on one table have all fallen, a ball will then travel on a cue to another table to start a similar chain reaction.
