I made a bowling ball one for the auditorium. It works ok. The smaller
one I have uses billiard balls and works great, certainly large enough
for a display case. But this is on the small side for the auditorium.

Hello all:

Say, does anyone know how large the
pendulum waves apparatus can be made as a practical matter? Any idea Dick(Berg)? 
I remember hearing somewhere fairly recently about a bowling ball sized
attempt which flopped, possibly due to undesired coupling. I'm thinking
of making a good sized one for a large display case. Thanks for any comments.
