"Genghis Khan."

Genghis Khan was no gentle persuader, so needless to say, this exhibition on the ruthless 13th-century conqueror is best suited for older kids. Interactive segments are in short supply, too, although kids will get a kick out of the giant trebuchet (a type of catapult) and crossbow, plus the traditional Mongol yurt. Not for the queasy, a mummy of a Mongolian noble woman resides in a darkened corner of the hall—accompanied by a sign warning of the display's graphic contents.
