There's a reason they never showed the whole cup while pouring

How do we know there wasn’t already soda in there that we couldn’t see ? ?

Last cup already had liquid in it

My hypothesis is someone with a straw drinking it down while the pouring

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.
Different cups, also its not soda.

This is indeed how the scientific method works

Soda loses arbonation when you pour it, and that gas takes up space, so you’re losing volume when you allow a lot of carbonation to escape. Open a coke, fill the cup and leave it out for a long time and the volume will probably go down

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.
