Cylinder in Motion

I advanced from the console to the center coffee table. A glass marble rested motionless beside a ceramic tray. I placed my right palm against its curved flank. Forward propulsion applied. The spherical mass rolled smoothly across the polished walnut plane. At the edge of the tray, it collided with a stainless steel spoon handle. Resonant chime recorded. The impact redirected the marble in a clean forty-five-degree trajectory toward a stack of square coasters. Friction arrested momentum against the cork border. Velocity zero. Trajectory confirmed.
