The reason Pringles fit so nicely in a cylindrical tube is because they're hyperbolic paraboloids plotted over a circular domainpic.twitter.com/BUzjPw7e17

Isn't it just because it's over a circular domain? They don't NEED to be hyperbolic paraboloids right?
yea i mean you could choose any surface not sure why they chose these ones though i can see why in the sense it's nice on the fingers

Probably easy to manufacture too?

Sorry, just saw what you said. You're right.

After seeing this, I looked up what hyperbolic paraboloids are. Apparently, its "a surface that may be generated by a moving line that is parallel to a fixed plane" - has 2 sets of such "skew lines." So this makes it easy to manufacture as well.

They stack nicely too

I think initially they were made like chips from a disk (slice) of potato. When deep fried, the potato shrinks, thus reducing its area but the circumference/skin can't shrink as much, then the hyperbolic paraboloid appears naturally as an optimal surface with boundary conditions.
