Persistence of Vision

PERSISTENCE OF VISION demonstrates how people can perceive a whole scene while only seeing a part of it at one time. The exhibit has a long tube with a slot at the end of it. The tube is held to one eye while the user moves it back and forth rapidly with the slot oriented vertically. Even though the slot restricts the view to only a small part of the scene at any moment, the tendency of the eye to retain images allows the observer to see the whole scene.
