angular momentum transfer?


I joined yesterday. I am searching for some information. I am a fairly new
student of physics, now retired, and I am presently searching for a
reference to a classroom demo that shows two wheels on a short axle, where
one wheel with lead (Pb) rim is spun up- and another wheel close by (on
the same axle) responds to the momentum change of the first wheel with a
small reverse rotation. I wish to replicate this so that I may study the
phenomena. Neither my text books nor Google however give a reference or
shows this demonstration. I'm confident however that a demo of this sort is
out there somewhere since a retired physics professor originally told me
about it. If anyone could please advise or give a science book reference or
to a correct Google search term, I would be most appreciative. Thanks.

Best Regards,
