Take a look at the bottom of your soda can. You'll notice that the bottom is indented and concave, with a little ridge that encircles the indentation.
This concave bottom design has one essential use. It makes it possible for the thin aluminum can to hold the pressure created by the carbonated soda. That's 90 pounds of pressure, or about six times greater than ground-level atmospheric pressure.
But that's not all. The bevel is encircled by an inset ridge. This allows you to neatly stack the cans, one on top of another.
And finally, a little known superpower: The ridge actually lets you open another can. Demonstrated by TikToker Jordan the Stallion, you can put one can on top of another, then use the ridge to catch and lift the pull tab. It opens neatly and your manicure stays intact.
