Basically title.
My basic physics knowledge says that the larger chips - near the top of a bag of chips - are not “stable”, they are kinda precariously balanced only at one or two points. But once the brittle chips break down, they tend to settle at the bottom because the crumbles are more “stable” there, and are at a lower state of potential energy.
Just my own theory, but would like to know what others think here.
Edit : Does this question not belong to this community ? I couldn’t explain the downvotes…
Kinda. Gravity is acting equally on all the chips but the smaller the chip the more gaps they are small enough to pass through, so the smallest chips end up at the bottom, collectively holding up the bigger chips.
