Question

Quizplus · Accepted Answer

Scott is attempting to re-create the Ponzo illusion, which is created when two parallel lines are placed across converging lines. The converging lines create a depth cue that tricks the brain into perceiving the longer line as being farther away and therefore larger. In this case, the straws act as the converging lines and the coins as the parallel lines.
