Hi:

   Is A perhaps a first law demonstrator? Balance a ball on an index card on
the brass stem and
   use the springy thing to flick the card out from under the ball?

   Is K perhaps a vacuum demonstrator? Perhaps it fits into a similar piece,
you pump the air out
   and show they can't be pulled apart. The handle suggests this to be,
although the classic demo
   is usually done with hemispheres.
