ME2.7 Rotating Stool

A student volunteer sits on the stool. Give him a horizontal spinning bicycle tire and to conserve momentum he spins in the opposite direction. Variations are many: spin him and watch the tire react, spin the tire while already sitting, etc. To demonstrate L's dependence on r and p, have a sitting volunteer sit on the stool with sufficiently heavy weights in his hand-approximately 2 kg. As he spins, have him bring his hands in towards his body and out away from it. His rotational speed increases and decreases respectively.
