A few years back, an employee at a Jack in the Box (or someone who just snuck into the food prep area of one) tried alarming folks who are suspicious of fast food beverage pricing structures to the "scam" that restaurants are playing on customers who decide to pay more for larger drink sizes. By employing an optical illusion, they literally had people convinced that all of the sizes were the same.

The trick is an easy one: You display the various cup beverage sizes all lined up, with the small one full and the other two presumably empty. Here's the thing though: You don't show the the inside bottom of the cup so it appears like it's empty, and you lead people to believe that they're all the same size, but they clearly, if you can look at them, are not.

That hasn't stopped this TikTok from going viral and shared a bunch of times, because every time a new social media platform debuts, people recycle the same meme trends over and over again. I wonder how long before "the dress" shows up on TikTok, or another variation of it, maybe with sneakers? Kicks manufacturers: Take note that if you want people to buy your product, rehash some old viral trend and apply it to whatever you're shilling.

Of course there are going to be people who claim that indeed, the drink "finesse" is real because, well, that's the hill that they want to die on, and invest all of their time and effort into proving when they're not advocating for Flat Earth Awareness. If you encounter friends of yours who swore that they will "only buy small" and go about their day thirsty after watching the video, I've disproved this little illusion below.

I guess I'm the moron though for leaving my house, going to a McDonald's drive through, and shelling out $3.20 for the drinks just to make a point. When my wife asked me where I was going, I just mumbled to myself, "Someone on the internet is wrong." 

In all honesty, I just really wanted a crisp Diet Coke.
