How to edit the HSTS "max-age" directive in Chrome?

I want to test what happens, when the HSTS "max-age" directive expires and the user visits my web application.

I know that proper behavior would be that, since HSTS has expired, the browser is willing to request HTTP content. However, I would like to see this in action.

How can I manipulate the HSTS "max-age" attribute in Chrome (or some other browser)?
