It’s been 22 years since the debut of the McDonald’s McFlurry (yep, once again, a reminder that you’re old), and in celebration, the fast-food chain is doing something that has almost nothing to do with blended ice cream treats. They’ve turned cardboard McDonald’s drink holders into iPhone speakers. Why? Why not, I guess. Oh, and here’s the kicker: Despite the fact that McDonald’s is pretty much synonymous with America, you can only get them for a limited time in select locations in Toronto, Canada.
To be fair, the McFlurry was apparently invented in Canada, which makes sense, given that it’s cold, delicious, and arguably one of the least gross things McDonald’s has on its menu. And while they’re definitely random, the speakers are pretty cool too. Part of a partnership between McDonald’s, the University of Waterloo’s Audio Research Group, and the Toronto-based design studio STACKLAB, the McBoombox (yep, that’s what it’s called) is the result of a project that sought to make usable speakers from recyclable materials.
But, like, does flimsy cardboard meant for carrying super-sized beverages actually work to listen to music, you ask? Apparently, thanks to the unique 10-sided cone design and reflective material used for the project (additions which, of course, aren’t native to your typical McDonald’s drink holders), it helps amplify sound up from your iPhone to 101 percent.
“When we changed the shape of the cones of the McBoombox, the difference in sound levels was 50 percent,” Janelle Resch, a PhD candidate at the University of Waterloo told Complex. “When we used the reflective material, you increase the sound level by 43 percent. Inserting your phone increases the sound level by 101 percent.”
Unfortunately, unless you live in Toronto and get your ass to McDonald’s ASAP, you may never know the feeling of blasting your favorite jams through a cardboard cup holder while going ham on a McFlurry.
