BIZARRE spinning toys

Hi Dianna, I would like to ask if anyone ever experimented this phenomena by spinning wheel in the ISS because there is no gravity? It would be interesting to see how would act huge space station built as a spinning wheel. Would it keep some orientation fixed or would just tumble randomly making astronauts sick. 
And even weirder is if you have wheel weighing 50kg stack on one side of 1m metal bar spinning really fast, you will be able very easily to lift it up with one hand even though spinning wheel will be further away from your body for the length of a metal bar. Very few well trained people can lift 50kg on a one side of 1m long bar let alone a untrained weak person with one hand.
