We created an optical illusion, a visual image that can be perceived differently depending on how you look at it. Scientists are still studying and testing why we see things the way we do. There have been a few theories about how they work. One theory states an optical illusion occurs because our brain is trying to understand and make sense of what we see. Sometimes the brain will use past images and experiences to try and understand what the eyes are seeing. In this experiment, the paper is moving so quickly that the brain is receiving information about the second picture as it is still processing the first picture. So cool!
