I do beekeeping presentations for various groups, including schools, using a
portable 1-frame-wide OB hive tall enought to accomodate 1 deep & 1 medium frame.
When I set it up before a presentation, I always include the queen from the hive I
take the bees from (and return them at the end of the day).
Invariably, the first question is "Where (or Which one) is the queen.  FWIW
