Videos are for watching, or for watching and listening to. Not these ones. These ones are primarily for scrubbing or soaking up, for cleaning.

Scenes from real life that would really get the benefit from a change, by passing a cloth over them and giving them a bit of a gloss. To do so, the user uses the scourer or cloth, scrubbing the image or soaking it up. And with this enjoyable cleaning action (like when you pass a cloth over a thick pile of dust, for example), the second image appears underneath; an image of change, of benefit.
