I am buying some potato chips. I want to use dip. But half the time I do my chips in the dip, they break apart.

Do wavy chips, with the wider bends have a greater strength? Or do the rippled chips, with the tiny bends have more strength? I am trying to find the best chip when it comes to dipping without the chip breaking.

Clarification based on the answers: Are rippled chips stronger than wavy chips? I am not asking about standard chips.

    $\begingroup$ The theory and existence of serpentine walls may be of some interest here. And even it not you should take the time so see a nice example somewhere as they are way cool. $\endgroup$ – dmckee Dec 29 '16 at 1:25

    $\begingroup$ i honest to god just spent around 10 minutes looking at serpentine walls $\endgroup$ – mochacat Dec 29 '16 at 1:31

Rippled potato chips are generally stronger. There's a reason why water bottles have grooves in them.

It's like trying to break a popsicle stick by applying a force parallel to its side or perpendicular to it. It is much stronger when you apply the force parallel to its side because there is more cross-sectional area that way.

    $\begingroup$ I basically just said that rippled chips are better for dipping. $\endgroup$ – Sigma Dec 29 '16 at 1:36

Yes they are. The reason is that their cross-section has a greater value of the second moment of area so they bend less easier. To give you a similar example ,try to google 'sheet metal roofing' and notice their formation.
