It is interesting how spring-shaped object have this bouncy characteristic quality about them. Even if its hair or just an ordinary spring, they snap back to their original shape. Why is it that corkscrew shapes are so elastic?

Springs as well as hair and rope all act as springs. Seriously all materials have this property.
However, there is a thing called the elastic limit. The elastic limit is the point where the material permanently distorts.
So with springs, you pull and they don’t snap back, hair breaks although there is a moment before that happens where it would have sprung back.
Try it with a paperclip.
Springiness is a property of matter.
Try looking up Hooke’s law.

And the Modulus of Elasticity.
