What are your browser screens incapable of scrolling ?
The fact that you scroll and you see it at the bottom is not remarkable. There's always a trailing edge of content on my screen that requires scrolling, including the country selector and the corporate info (eg: copyright info) - the nature of laptops. Telling them to scroll doesn't demonstrate what's going on. It's the resizing and re-arranging that occurs on a larger screen to manoeuvre their non-preferred content off the screen that's noteworthy, and not demonstratable on a smaller screen.
