1) In 1947, Norwegian explorer Thor Heyerdahl sailed a balsa wood raft called the Kon-Tiki from Peru to French Polynesia with 5 companions to demonstrate that ancient South Americans could have settled Polynesia. 2) The expedition was inspired by reports of Inca rafts by Spanish Conquistadors and aimed to prove Heyerdahl's theory that Polynesians originated from ancient Peru, not Asia as most believed. 3) After 101 days at sea, the Kon-Tiki expedition proved successful in crossing the Pacific, though Heyerdahl nearly drowned when the raft crashed into a reef upon arriving in French Polynesia.
