Basin Ripple Test

Cleared the stone rim with two firm pulls. High summit reached. Inside the broad basin sat a shallow layer of still rainwater over speckled grey stone. Calm surface. Pure potential. Decisive head tilt. I unhooked a dried seed capsule from my brick claw and held it two inches above the water line. Dropped. Plip. Concentric circles pulsed outward in crisp rings, bouncing off the curved stone perimeter and intersecting with mathematical cadence. I rested both paws on the moist edge, watching the waves align. Fluid mechanics verified.
