People are grossed out after a video shows how long McDonald's paper cups can hold liquid

People are obsessed with McDonalds and time-lapse videos and this one is certainly a fascinatingly disgusting watch.

If you delve into the depths of YouTube, you'll find time-lapse videos of all kinds.

And you shouldn't have to dive too far until you find a few amateur experiments examining how long it takes McDonald's food to develop mold.

However, in 2020, a YouTube channel created a time-lapse to see how long a McDonald's cup could hold a liquid. I mean, this year there was a lockdown for a lot of people, so there really wasn't much to do.

But while the result may surprise you, it might just as disgust you.

YouTube channel Photo Owl Time Lapse insisted that the purpose of the video was not to disparage the company, but rather that the channel praised the company for its years of environmental efforts.

Explaining the experiment, the video caption read: “Have you ever wondered how long your drink can last in a McDonald's paper cup? Me too.

“Watch this time-lapse video of McDonald's paper cups to find out.

“I took more than 124,000 photos for this project. I had to take a very frequent break, otherwise I would have missed the interesting moment when the cup finally broke.

“It was orange juice, Pepsi and water. I removed the water so early because nothing interesting happened to it, it just slowly evaporated, and removing that cup gave me more screen space for the two remaining ones.

“And for the same reason, I also removed the Pepsi so I could get closer to the orange juice cup, which looked the worst. I added water from time to time, otherwise it would have evaporated many times over, and the main goal was to “break” the cup.

Five days pass and the water and Pepsi seem fine, but the orange juice quickly begins to mold.

By day 7, the orange juice cup is black and has black mold, while the Pepsi is starting to develop small spots of mold.

After about 50 days, the orange juice cup begins to break down and leak.

On the 90th day, the experiment only focuses on the cup of orange juice and the mold continues to proliferate and grow.

On the 200th day the cup begins to tip over and loses its shape, and by the 231st day it is completely tipped over and very thin.

People on social media admitted that the whole experiment was pretty gross, but weren't surprised that the orange fruit drink accumulated so much mold and the paper cup ended up weakening.

“Kudos to this guy, rotting sap must have smelled terrible!” one user wrote.

“I took a sip of my orange juice when it started forming in the video, that's always fun,” another added.

“Even though it's totally gross, it was strangely beautiful to watch the juice turn into mold in fast motion,” commented a third.

“Yeah, watching this while eating isn't the best idea I've ever had,” one horrified user added.

“It started out interesting but very quickly took a dark turn when the gray took over. Props for keeping this biohazard in your studio/garage/mad scientist lab/whatever for almost a year,” a fifth person commented.
