Go to the site and then look at the two long lines.
Which one is longer? Try moving the two lines on top of each other. Try swapping the end pieces around.

I love this illusion because most people think that the top (a) is longer but when you switch the arrows around it shows that both a and b are the exact same size which tricks are minds, because its like looking at a class of water in a short class and having a glass thats tall and skinny which hold the same liquid. What I find the most interesting is at what age does our minds understand an illusion because if you were to ask a child which line was bigger or which class could hold more liquid they would choose line a and the tall skinny class cause to them it is bigger, just weird how something can be so similar and so different.
