Basic standards

Key standards

Visual physical commonsense (V-PC)

• The metal screw turns under a screwdriver or drill and visibly advances into the wood with continuous rotational motion, at a depth consistent with the screw's physical length.
• The screw remains a metal screw throughout the clip and does not morph into a different material.

Audio physical commonsense (A-PC)

• The sound is a rhythm of sharp metallic threading clicks consistent with metal threads engaging wood.

Cross-modal physical commonsense (AV-PC)

• The clicking sounds coincide temporally with the visible turning of the screw.
