Air

That's why I choose Pringles. They're stacked on top of each other and packaged in cylinders. That way, they store the most chips with the least air.

I never thought about that before. Thanks for telling me

I understand the logic but pringles aren’t actually potato chips

Really? Why not?

Pringles are made from a dough of dehydrated potato flakes, corn flour, rice flour, and wheat starch while potato chips are made from potatoes

There's also Lay's Stax. They come in cylinders.
