While studying with my friend Patrick Desjardins, we came across this photo.
Patrick pointed out that this hyperbolic plane figure looked like a dried apple. Well, that sparked an interest! Why do we get different shapes when we shrink fruit that when they are dried? Are they really hyperbolic? I needed answers. First I sliced "naked" apple slices (apples with no skin). They appeared much curlier, as you can see.
My next question was gravity. I took four slices, two with skin and two without, and hung them from the center to observe how they dried. They both appeared to by hyperbolic.
Even cutting from different parts of the apple (top to bottom not core to core), the result was hyperbolic. I concluded that the cellular drying process creates the hyperbolic in foods such as apples (this is why potato chips have a similar shape).
