eli5: how do noodles retain their shape in liquid for so long?

I just opened an oldish can of soup and the noodles have been submerged in liquid for months yet the flour and stuff in the noodles doesnt disintegrate into mush, yet when you try to chew it there's zero resistance and it feels like you're chewing nothing, why?

Noodle starts as solid piece, very thin (Usually wheat).

Noodle becomes full size when it absorbs water content.

Noodle (in soup) is mostly water. Water does not have much resistance in this context therefore noodle also has little resistance.
