You start by setting up the balls as diagrammed (any three colored balls will do) and placing one ball at rest, atop the other two in the middle of the short rail on either end of the table.
The next photo will show the setup more clearly. Announce to your adoring audience that you are able in one try to strike the cue ball in such a manner that you can hit the 8-ball cleanly without the white ball touching the other two!
