Why do chips and similar things curl up when frying?

670 views

Chips come in all kinds of shapes and I was just wondering what the physics behind that is (if this even has to do with physics), bc the oil alone shouldn’t have such an effect.
I know it’s kind of a random question but I just couldn’t explain it to myself.

during the process of being fried in an open vat the slice of potato expands and contracts unevenly.

Pringles uses a mold to make the shape they come in while frying.
