Some teens who went out clubbing came back with lots of pictures of their night, but one in particular has become very popular. In it, 18-year-old Eleanor Bailey's arm looks super-long because of an optical illusion.
It turns out, her arm is actually behind her, but because your brain sees a strip of black about the same size on the shirts of the people next to her, it makes you think her arm is just that long. However, the arm you are seeing really belongs to the girl near Eleanor.
