Not much as a tabletop demonstration! I did some searching on the web and found that it was called, "Tickling the dragon's tail." I found lots of references to the 'ootching slugs of metal near each other on a table' experiments that killed two people, the second of which was Louis Slotin. See http://en.wikipedia.org/wiki/Louis_Slotin. I also found one reference to dropping material through holes.
