I like that idea. I'm thinking a little drop through an oversized Pachinko machine. Prizes for anyone betting on the hole it ends up in.
OTOH, the thing was used in the 20th century, and not by the French, but the Nazis. Very efficient. Not the best advertisement, though.
I think the French used it or could use it up through the 1960’s
Perhaps it's time to hide the entire thing behind some hippie-dippy new-age ceremony, similar to "Carousel" in Logan's Run.
