@jamiemccarthy An example would be 0:48 in the "electrons do NOT spin" video above, where he describes, but does not fully explain, an experiment involving the basic "an EM field can make a metal thing rotate" behavior.
I have also seen an experiment described where you fire a beam of particles with a specific quantum spin at a macroscopic object and eventually it starts rotating. Because I don't have a cite on this experiment, it is possible that I have misunderstood it.
