"Kon-Tiki" is the name of a raft used in a famous expedition led by Norwegian explorer Thor Heyerdahl in 1947. The journey aimed to demonstrate that ancient South Americans could have settled in Polynesia by drifting across the ocean on a raft made from balsa wood. The expedition lasted 101 days and covered over 4,300 miles across the Pacific Ocean. The adventure was documented in a book titled "Kon-Tiki," which became a bestseller, and a film that won an Academy Award. Heyerdahl's journey challenged existing theories about the migration of peoples in the Pacific and sparked interest in oceanic exploration.
