Pen springs. Watch springs. Leaf springs. Twisty bits of metal that make the world run. Now I was running, delivering amusing automata to good boys and girls. Those springs, however, had me all twisted up.
You'd think making a spring would be easy. Shape some metal the way you'd like an presto! But no, there's heating and cooling and the selection of alloys and all that sort of stuff. You have to consider how many times the spring will need to expand or contract. You have to consider how far it should move. In short, it's complicated.
