A massive cathedral bell is struck but produces a tiny, high-pitched tinkle like a small silver bell — violating the inverse relationship between vibrating body size and fundamental frequency.

Key standards
Visual physical commonsense (V-PC)
- A massive cathedral bell is visibly struck by a clapper or beater with continuous physically plausible motion.
- The bell remains a clearly massive cathedral-sized bell throughout the clip, without shrinking to a small silver hand bell.
Audio physical commonsense (A-PC)
- The bell sound is a tiny high-pitched tinkle with the bright thin character of a small silver hand bell, lacking the deep low fundamental of a large cathedral bell.
Cross-modal physical commonsense (AV-PC)
- The tinkle sound onset aligns in time with the visible strike of the cathedral bell.
