Video Description: A thin man who appears to be white sits on the opposite side of a windowed enclosure from a young orangutan. The man holds a styrofoam cup. He tilts it, to show the orangutan that there's a sweetgum seedpod inside of it. The orangutan watches him intently as he puts the lid on the cup, then shakes it up, then lowers it, so that it's just out of the orangutan's field of vision, where he quickly empties it. He brings the cup back near the window, shakes it again, then removes the lid and reveals that the seedpod is gone. The orangutan looks at it curiously, then breaks up into laughter and falls over. The man and a woman holding the camera laugh.
