Next stop is China as we learn about the incredible Terra Cotta Warriors exhibition hosted by the Field Museum in Chicago. These larger-than-life figures stood guard over the China's first emperor in his tomb for centuries until they were accidentally discovered by a farmer in his field. Next we visit Italy and the collection of machines designed by Leonardo da Vinci. This special exhibition traveling North America featured the drawings and models of many of da Vinci's inventions including, the bicycle, the helicopter, double hulled boats, and winged gliders.
