Why soda cans have a concave base

There’s a new kind of revelation happening in kitchens lately—and it’s not coming from a new gadget, a seven-in-one appliance, or even a celebrity pantry makeover. It’s coming from soda cans. Yes, the aluminum kind you’ve been popping open for years without a second thought. They’ve been sitting in your fridge, stacked neatly like chrome sentinels, their matte pull-tabs waiting patiently. But if you’ve spent any time on TikTok recently, you know that the humble soda can is having a moment—and this one isn’t about branding, flavor wars, or the endless debate between Coke Zero and Diet. It’s about design. More specifically, it’s about the beveled bottom. That subtle indentation. That functional little concavity you’ve probably seen a thousand times and never questioned. Until now.

It turns out that tiny curve has a secret second life—and the internet is gleefully shouting it from the virtual rooftops. According to a now-viral TikTok from creator @Jordan_The_Stallion8, the beveled bottom of a soda can isn’t just for stacking. It’s also the perfect tool for opening the can beneath it. With one slick move, you can wedge the bottom of one can under the tab of the next, apply a little pressure, and pop it open—no nails required, no finger-pinching necessary, and no embarrassing flailing when you realize you’ve just ruined a fresh manicure trying to pry open a reluctant tab.

For those whose lives orbit around small pleasures—perfect fridge organization, satisfying routines, and design details that work as well as they look—this is a revelation. And it’s sparking more than just a round of enthusiastic beverage opening. It’s become a minor cultural moment, wrapped in domestic ritual, TikTok cleverness, and that universal human thrill: discovering you’ve been doing something the hard way all along.

This is where aesthetics and utility meet. This is where soda cans enter the design chat.

Long before TikTok got involved, the beverage can’s beveled edge was a quiet workhorse of modern engineering. It wasn’t added for flair or visual balance. It exists because carbonated drinks are volatile. The pressure inside a typical soda can is nearly six times the regular atmospheric level. That’s roughly 90 pounds per square inch of internal force, pushing outward against a thin aluminum wall. The concave bottom helps distribute that pressure efficiently, making the can less likely to buckle or explode. The beveled rim helps it sit flush on a flat surface, adds stability during production and transport, and—perhaps most importantly for today’s fridge-packers—makes cans stackable without slipping. It’s a design feature that sits at the intersection of physics and visual satisfaction, which is why beverage cans rarely roll off supermarket shelves unless provoked.

But what makes this revelation feel so zeitgeisty is that it doesn’t stop at function. The hack—the act of using one can’s bottom to open the next—is deeply satisfying. It’s the kind of clever workaround that doesn’t just feel efficient; it feels like a shared secret. Like something you weren’t meant to know, but now that you do, you’ll never un-know. It’s deceptively simple, oddly elegant, and suddenly, you’re seeing soda cans not as packaging but as tools, interconnected and intelligently designed.

This is the part where lifestyle shifts and digital behavior start to blend. Because what TikTok has done—again—is take something deeply ordinary and reframe it through the lens of platform culture. Just like we learned that the hole in a pasta spoon is actually a serving size, or that the little drawer under your oven isn’t for storage but for keeping food warm, the beveled soda can moment follows that exact trajectory. It starts as a visual demonstration. Then it becomes a meme. Then it becomes a small part of how we organize, move, and interact with our domestic spaces. The hack isn’t just about making life easier. It’s about turning the everyday into something performative, clever, and quietly joyful.

What makes it even more viral is its aesthetic universality. It doesn’t require a specific brand, a new gadget, or even a fancy fridge. You don’t have to download an app or buy anything. You just need two cans, and gravity does the rest. In a world saturated with productivity hacks that demand subscriptions or “wellness” tricks that start with “first thing when you wake up, drink lemon water and meditate for thirty minutes,” this is the kind of low-barrier genius that feels both accessible and elegant. It’s also a perfect candidate for TikTok’s video format: fast, visual, repeatable, and vaguely mysterious until the final satisfying pop.

Part of the appeal is also aesthetic. Soda cans are already visual darlings of the organized fridge world. They’re symmetrical, glossy, and satisfyingly tactile. They slot into bins with precision and align neatly on shelves, often color-coded or chilled to perfection. TikTok has turned fridge curation into an entire subgenre of content: the restock video. You’ve likely seen one. A pristine fridge door opens to reveal a choreographed ballet of drinks being unpacked and slotted into place. There’s a rhythm to it. A satisfying whoosh of air. The glint of aluminum. A sense of order. This hack folds neatly into that ritual—it’s another layer of efficiency, a hidden feature unlocked in plain sight.

It’s also part of a larger cultural pattern: the fetishization of the everyday. There’s something deeply millennial and Gen Z about finding delight in domestic mastery. This is the generation that grew up in chaos—financial, environmental, digital—and found solace in the small ways they could control their world. A color-coded bookshelf. A drawer where every item has a place. A pantry arranged like a boutique. These are not signs of superficial perfectionism. They are survival aesthetics. Beauty as structure. Calm as control. In this context, discovering a better way to open a soda can isn’t silly. It’s quietly revolutionary.

But of course, this wouldn’t be a proper cultural phenomenon without its backstory—and the beverage can has one. Aluminum cans didn’t become mainstream until the late 1960s, when beverage companies like Coca-Cola and Pepsi began transitioning from glass bottles to more efficient, stackable, and transport-friendly packaging. At the time, it was a decision driven by logistics and cost. But over time, it gave rise to one of the most iconic container forms in modern consumer history. The aluminum can is lightweight, durable, endlessly recyclable, and—crucially—modular. That stackability is not incidental. It’s a core part of how beverage distribution, retail, and domestic storage evolved.

What TikTok has done is retroactively celebrate that evolution. It’s taken a piece of industrial design and reframed it as an object of beauty, intelligence, and small-scale delight. It’s a moment that makes you stop and appreciate the details: the way one shape fits into another, the way leverage and friction can replace brute force, the way good design hides in plain sight until someone points it out.

This shift isn’t just happening with soda cans. It’s happening across domestic life. The microwave vent that doubles as a splash guard. The kitchen sponge holder that actually drains into the sink. The pasta jar with an angled lid for cleaner pouring. We’re witnessing a re-romanticizing of household items—not because we’re becoming more domestic in a 1950s way, but because we’re hungry for a sense of agency in our spaces. A soda can that opens another soda can without fuss? That’s a tiny act of liberation. It’s design justice for acrylic nail wearers. It’s a win for tactile intelligence in a world that often forgets the physical.

There’s also a quiet humility to this kind of viral moment. It doesn’t ask you to change your lifestyle, sign up for anything, or perform some radical overhaul. It doesn’t judge your fridge contents or your drink preferences. It simply says: here’s a better way to do something you already do. No fanfare. No filter. Just the sound of a tab clicking into place—clean, crisp, and oddly satisfying.

And maybe that’s why this moment matters more than it seems. In a culture that often equates transformation with grand gestures, the beveled soda can trick reminds us that transformation can also be minute. It can be one object helping another. It can be a small shift in perception that rewires how we engage with the world. The soda can didn’t change. We did. We started noticing. We started sharing. We started building micro-rituals out of what used to be muscle memory. And in that noticing, we found something to love.

Because ultimately, what the beveled bottom moment really offers is an invitation—to pause, to observe, and to reimagine the tools we already have. To see design not as decoration, but as quiet, persistent function. To experience our homes not as static places, but as systems full of potential. And to remember that even the smallest friction—like a stubborn pull-tab—deserves a little grace, a little hack, and a lot more attention.

So the next time you open your fridge, look at those cans a little differently. Not just as beverages, not just as cold refreshment, but as small, engineered marvels. As participants in a dance you’ve only just learned the steps to. And if you reach for one can to open another, smile. You’re not just opening a soda. You’re participating in a quiet act of design literacy, domestic pleasure, and collective discovery. All thanks to a little bevel. And a lot of curiosity.
