The world's oldest known message in a bottle was discovered over a century after it was thrown into the sea. In 2018, a beachcomber named Tonya Illman found a bottle on a beach in Western Australia. Inside the bottle was a rolled-up piece of paper from 1886, making it the oldest-known message in a bottle. The message was thrown into the Indian Ocean by the German ship Paula as part of a scientific experiment to study ocean currents.
