The "Bermuda Triangle" looks like a complicated trick shot using additional billiards equipment (rack) and sophisticated pool techniques such as jump shots. But Vincent Facquet displays it as a simple trick shot, so who are we to argue with a world pool trick shots champion?

First, the farther ball from the pocket is hit and fell into the opposite right corner pocket. While that happens the cue ball hits the rack, causes it to flatten on the table, drop down the upper ball, which jumps over the ball closest to the pocket and falls down to this pocket.
