Reaction wheels - animation or video?

[GoshenSpace]

I will be teaching a course at my local OLLI branch (a membership organization offering extended learning opportunities to older adults as well as social and recreational activities) on design of spacecraft. Since these folks are non-technical, I am sprinkling my course with lots of videos, animations and pictures. I would love to find a video or animation that displays the working of reaction wheels for 3 axis spin stabilized spacecraft. Does anyone know of such videos or animations?

Thank you.
