Actually what VCTMike is proposing is what I was going to do! Last show of our season is NTN. you can
pick up a packet of rare earth magnets at Harbor freight for $4 or something. just drill divots and
epoxy then into the seams. Rather than "weak magnets" you want something that will hold up to handling. We did a similar thing for "3 sisters" last year, one of the daughters throws a small china clock and it's supposed to break every night, that one we molded out of PLasticene then embedded the magnets.
