Key standards

Visual physical commonsense (V-PC)

  • An alarm clock is visibly ringing both above and below the water surface, and is lowered with continuous motion into the tank.
  • The clock retains its alarm hammer, bells, and clock face throughout the clip.

Audio physical commonsense (A-PC)

  • The ringing in air is clear and unmuffled.
  • The ringing underwater is noticeably more muffled and hollow than the above-water ringing.

Cross-modal physical commonsense (AV-PC)

  • The shift to muffled ringing coincides temporally with the clock entering the water.
