Bending Lines Illusion
What to see and do: When you first look at this illusion, you shuld see two lines that are slightly bent. If you move the two lines, you will see that they are straight! Try moving the lines around and watch them appear to bend upward and downward.
What's happening: The lines going out from the center of the circle make your eyes think that the lines are bent but they are really not.
