I tried the McFlurry cup-stacking hack going viral on TikTok and ended up with a giant mess
- David Dobrik shared a TikTok video of himself trying a viral McDonald's cup hack on January 25.
- He stacked a McFlurry on top of a soda cup and tilted both sideways without spilling anything.
- I tried the same trick and ended up with sticky Oreo crumbs everywhere.
TikTok hacks can be useful and fun, but they don't always work - and some attempts are messier than others.
According to one recent TikTok hack that went viral, you should (in theory) be able to stack a McDonald's McFlurry cup on top of a soda cup and tip the stack of drinks sideways, all without spilling anything.
But I tried it - in the name of science, of course - and ended up with Oreo bits everywhere. I'm still vacuuming the mess two days later.

David Dobrik tried the McFlurry stacking trick in a TikTok video
The so-called hack was popularized by YouTuber David Dobrik, who shared a video of himself trying the trick in his car on January 25. The video has 11 million views on TikTok at the time of writing.
"Alright guys, I saw this on TikTok. Let's see if it's legit," Dobrik can be heard saying from behind the camera.
He goes on to point the camera in the direction of his McFlurry, which appears to be Oreo-flavored, and an orange soda. He places his smaller McFlurry cup on top of the soda cup and gently presses down on the slightly raised circle within the drink lid where the straw typically goes.
You can hear a small click sound followed by Dobrik and his crew's very loud celebrations.
"Bro, it f----- works! Look!" Dobrik says.
Then, and this probably the most stressful part of the video, he tips it to the side - but there's zero spillage. Not a drop of ice cream or orange soda spills out from either cup.
"My anxiety over a clean car was ," one TikTok user wrote.
"Me waiting for it to fall ," another said.
The McDonald's social-media team caught wind of Dobrik's video and left a comment saying, "and y'all thought my only secret was sauce."

Dobrik isn't the only one who has gone viral for sharing this surprising trick. There is at least one other popular video of someone else successfully trying out the hack inside a car, although they don't tip it to the side like him.
McDonald's didn't immediately respond to Insider's request for comment.
I tried the McFlurry stacking trick myself and failed miserably
I measured the diameter of the base of the McFlurry cup and the raised circle in the drink cup and they both came to 5.7 centimeters. So, in theory, the trick should have worked. I got an orange soda and an Oreo McFlurry to match my order to Dobrik's as best I could.
But when I stacked them, I didn't hear the "pop" sound that was audible in Dobrik's video and nothing about my setup felt as secure.
It's possible that my soda cup lid was slightly different than Dobrik's. My lid had raised text that said, "Don't waste the taste," and because of that, it wasn't a perfect circle. As a result, the McFlurry cup didn't lock into place.
When I tipped my cup tower sideways, I ended up with this mess on my table and Oreo crumbs all over the floor:
Even though McDonald's fries are uniformly delicious across states and countries, not all cups might be exactly the same. So, a word of caution: Make sure your cups actually lock into place, and the hack might be successful for you.
This isn't the first viral McDonald's claim that turned out to be a major fail.
Insider's Palmer Haasch previously disproved a separate viral TikTok which claimed that every size McDonald's cup holds the same volume of liquid.
