I mean, you can just google "pringles super computers" They did use a supercomputer in modeling the thing, most articles are useless cuz they're not going to go into details about how or why.

or here's a CNN article about it. the blurb is just

"Pringles potato chips are designed using [supercomputing] capabilities -- to assess their aerodynamic features so that on the manufacturing line they don't go flying off the line," said Dave Turek, vice president of deep computing at IBM. Personally, though, you're missing out on this gem

Keep in mind, pringles were around since 1968, apparently. modeling and simulating dynamic airflow was probably barely in it's infancy. (and even to day, computational fluid dynamics is some exceedingly hard math to rock)
