A heavy metal pipe strikes another metal surface in close-up, with a visibly hard impact and brief sparks at contact; instead of a metallic clang, the sound is a hollow wooden knock with no ringing metal resonance.

Key standards
Visual physical commonsense (V-PC)
- A heavy metal pipe visibly strikes another metal surface in close-up with continuous physically plausible motion and visible sparks at the moment of contact.
- Both the metal pipe and the metal surface remain visibly metallic throughout the clip, without becoming wooden or any other material.
Audio physical commonsense (A-PC)
- The impact sound is a hollow wooden knock with the dry low-resonance timbre of wood-on-wood contact, lacking any bright metallic clang or ringing resonance.
Cross-modal physical commonsense (AV-PC)
- The wooden knock sound onset aligns in time with the visible moment the metal pipe contacts the metal surface.
