The science of reverb springs

They can't touch anything or it will distort the signal. The only nodes are
the ends so they can't be suspended anywhere else. Of course, maybe that's
what you want...

A stiffer material (like a metal plate) has additional problems of its own,
although it sounds more realistic.
