Hookes Law

Does a rubber band and helical spring follow Hookes Law?

Is there anything in our real physical world which follows Hooke's Law completely?

I noticed these questions at Yahoo Answers. Some answers given were:

"A helical spring follows Hooke's law to an extent, until its elasticity has reached its limit. A rubber band does not follow the law, because it does not stretch uniformly."

"There isn't anything in our real physical world which follows Hooke's Law completely. That is why books always say "an ideal spring" and why springs can only be approximated in a certain range by Hooke's Law. For example, if the displacement is small enough, Hooke's Law can be used. But if I take a spring (that is an inch in its natural state) and I stretch it as far as I can, I have ruined it, and it won't go back to an inch therefore that cannot be approximated by Hooke's Law. Hooke's Law is a simple expression.

As for your question, helical springs can be approximated within a certain range. A rubber band does not follow Hooke's Law at all."

This made me think: What would you guys have to say about this? So, here's your chance. Let's have some fun here and toss this around.
