Level Balance Test

I stepped down from the fabric onto the flat wooden desk. The surface was rigid and stable. I located a metal hexagon nut near an open sketchbook. I tested its mass with my right foot, then braced my frame. Using both hands, I rolled it precisely three centimeters until it aligned flush against a wooden pencil. A small glass marble rested nearby. I nudged it toward the gap. It rolled along the pencil's edge and settled firmly against the nut. The three components formed a locked triangular contact point. My center of gravity remained aligned.
