There was a small gimmick made in Israel, I believe, held in the hand that works just fine with one very large caveat: you have to be extremely careful of the broken glass.
Glass-breaking brings up all sorts of problems, mainly safety and liability. Most of these things are spring-loaded and there's the problem. You would be amazed at the distance even a small, hand-held device will spread the broken pieces.
When I directed a friend's show I insisted on laying down a cloth cover for the stage. Even with it 10 feet square and him standing on one side, some glass scattered beyond the confines of the tarp.
Of course, common sense dictates that nothing is aimed at the audience, but if you're working with a table device you MUST be concerned about offstage personel who could be injured.
Your own liability insurance may or may not cover you. If it doesn't, be prepared to find out how expensive personal liability can get.
