Visual physical commonsense (V-PC)

- The gym floor remains visibly dry throughout the clip, with no water, puddle, or moisture present at any bounce point.
Audio physical commonsense (A-PC)
- Each bounce sound is a clear water splash with the wet liquid character of shallow water disturbance.
Cross-modal physical commonsense (AV-PC)
- Each splash sound onset aligns in time with a visible contact between the basketball and the floor.
