What kind of lab could I do to demonstrate conservation of angular momentum?

>Get small person
>Sit them in an office chair
>Tell them to bring their arms and legs in
>Spin them around
>While spinning tell them to spread their arms and legs out
>Watch as spinning slows down.
>Repeat experiment with arms and legs spread out.
>Begin spinning
>Bring arms and legs in
>Watch as spinning speeds up.

It has to be a measurable experiment, not just a demo. That is fun though.

get a vertical metal rod and attach a weight to the top with a rope.
then spin the weight around the rod. as the rope wraps around the rod the radius of the weights circular motion decreases and it makes more rotations per second.
