Last time I was there (10 years ago?), there was indeed a glass
harmonica on display, and it was playable.  It was in a huge children's
"hands-on" public educational area, and anyone could go right up to
it, push the button to start the electric motor, and play it.
Perhaps someone in the area could stop by or call and inquire if
it's still on display and useable.
