While standing with arms extended and rotating on a rotating platform, have the volunteer bring the weight to there chest to help illustrate conservation of angular momentum. If necessary, one can sit on a stool that is placed on the rotating platform as well. The person now rotates faster. To slow down have them just re-extend there arms. Note that only the speed of rotation changes not the direction of rotation like with the bicycle wheel.
