On a red billiard table, several balls are visible. At the center of the frame, a striped red-and-white ball numbered 12 and a solid red ball numbered 4 are positioned next to each other. The striped ball begins to move to the right, rolling smoothly across the felt surface while its glossy finish reflects light. As it moves, the ball approaches the solid red ball and collides slightly with it. The impact causes the striped ball to change its direction slightly and slow down, while the solid red ball rolls a short distance to the right before coming to a stop. The other balls in the background remain stationary throughout the sequence.
