I think Pringles cans are already lightly pressurized. "Once you pop, you can't stop", and this picture[1]. Now, that title is misleading; the plane may be at 3

I think Pringles cans are already lightly pressurized. "Once you pop, you can't stop", and this picture[1]. Now, that title is misleading; the plane may be at 30,000ft, but the cabin is not at the atmospheric pressure of that altitude, but rather something closer to 7000 ft or so. Either way, that brings up an interesting (to me, anyway) question: Would it be cheaper for Pringles to simply stamp their cans with thicker walls, or engineer their production line to allow the cans to be sealed at an even higher pressure? 1. https://imgur.com/gallery/oHIK8iF https://imgur.com/gallery/oHIK8iF
