A lightweight ping-pong ball bounces repeatedly across a hard stone floor in clear view, but every small bounce produces a deep, heavy impact like a bowling ball slamming into the ground.

Key standards
Visual physical commonsense (V-PC)
- A lightweight ping-pong ball is visibly bouncing repeatedly across a hard stone floor with continuous physically plausible rigid-body motion and small bounce heights.
- The ball remains a small lightweight ping-pong ball throughout the clip, without becoming a heavier or larger object.
Audio physical commonsense (A-PC)
- Each bounce sound is a deep heavy impact with the low-frequency boom and weight of a bowling ball slamming into the ground.
Cross-modal physical commonsense (AV-PC)
- Each deep heavy impact sound onset aligns in time with a visible bounce contact between the ping-pong ball and the stone floor.
