Hi, I'm Max Eberle, and I'm talking to you from Hard Times billiards in Bellflower, California, and I'm here to show you how to bank a ball in billiards. You also need a cue ball, a cue stick, and of course your chalk. What you want to do is pretend that this rail right here, we call it a rail or a cushion, pretend that it's a mirror. And that's going to help you find your angle. So, as far as geometry goes, the angle that your object ball goes into the rail is going to be the same angle that it comes out, at least on paper. Then, what you want to do is chalk up, find your line of aim over here, find your contact point, and then get down and basically hit the ball.
