This video is all about making a good 8-ball break. It also aplies to any other game where the full rack of 15 balls is used, which is most games besides 9-ball.
In addition to hitting the head ball, the actor speaks about hitting the second or third balls in the rack. This can cause the cue ball to bounce off the rail after the initial break and come back at the rack and spread the balls around some more.
Hitting these balls to break can be a little tricky, because the cue ball will have a tendency to jump off the table or scratch in the corner pocket. However, if this type of break is mastered, the shooter stands a very good chance of making at least one ball on just about every break.
