Here is a cool shot of someone doing some billiard trick shooting with a bunch of dominoes on the pool table. I'll tell you he's got infinitely more patience than I.
It starts with a combo shot or a split hit, which sends two balls in to two pockets, and triggers the dominoes. The cool thing is that the setup actually uses five Brunswick pool tables. My favorite is the execution of the very last table. 7 object balls going in to the same pocket, one immediately after another.
