"Kon-Tiki" was the name of a wooden raft used by six Scandinavian scientists, led by Thor Heyerdahl, to make a 101-day journey from South America to the Polynesian Islands. The purpose of the expedition was to prove Heyerdal's theory that the Polynesian Islands were populated from the east- specifically Peru- rather than from the west (Asia) as had been the theory for hundreds of years. Heyerdahl made a study of the winds and tides in the Pacific, and by simulating conditions as closely as possible to those he theorized the Peruvians encountered, set out on the voyage.
