The ‘Fast Food Cup Illusion’ Is Blowing People’s Minds–And We Have Some Questions

Although anyone who watched the video was stumped initially, another Twitter user recreated the experiment and closed the case on this optical illusion– The final large-sized cup is not full.

But THEN people pointed out that she was using different cups, and also not using soda, which sparked a whole debate on whether the difference in liquid could’ve changed the outcome.

So, while maybe debatable, it seems the video is nothing more than a trick. And here I was thinking we really had a class action lawsuit against Jack in the Box on our hands.
