An onion is sliced cleanly in half; the sound is brittle and glass-like, resembling ceramic cracking rather than moist vegetable layers separating.

Key standards

Visual physical commonsense (V-PC)

  • An onion is visibly sliced cleanly in half by a knife with continuous physically plausible cutting motion, and the moist onion layers visibly separate at the cut.
  • The onion remains a recognizable moist onion throughout the clip, without morphing into a ceramic or glass object.

Audio physical commonsense (A-PC)

  • The slicing sound is brittle and glass-like with the sharp cracking timbre of ceramic fracturing rather than the moist crisp character of a vegetable being cut.

Cross-modal physical commonsense (AV-PC)

  • The brittle cracking sound aligns in time with the visible knife passing through the onion.
