    Look carefully at the center circles
    on both the left and right.
    Which circle is bigger?


    Are you sure they aren't both the
    same size? This relative size
    illusion is called the Ebbinghaus
    illusion. It was discovered by
    Hermann Ebbinghaus, a German
    psychologist, in the early 1900s.

    Take a closer look, it could be a
    grouping of circles.

    Is the blue side in the front or
    back of the cube?

    Are the lines below straight or are
    they curved?


    Try putting a straight edge
    against the lines on your screen
    to test your conclusion.
