How to make this soap film like metal material?

Hi,

I'm new to Octane here. Saw a picture of these swim rings render and was attracted by the material on the top swim ring.
What is the correct name describing this kind of soap film metal like material? And how to make it?
Tried to mix soap film and aluminum material but failed.
Hope someone can give me a hint how to make this.

Thanks!

Hi,
use a procedural noise in the Film width pin, to give different widths to the film, and play with the Film IOR value.
