The Floating Perimeter

I followed the sidewalk expansion lines all the way to the circular stone fountain basin in the park. Resting right near the mossy rim was an intact, dried oak leaf, curved like a shallow hull. Instead of just noting its angle, I decided to test its seaworthiness. I stepped carefully onto the wet concrete ledge, gripped the dry petiole with both hands, and eased the leaf onto the still water. It floated—without taking on ballast. To map the water’s subtle surface drift, I dropped a tiny, rounded white quartz pebble right into the leaf’s center. The leaf settled two millimeters lower, drifting in a slow, elegant circle across the mirrored surface.
