What's the furthest a message in a bottle has travelled?
If you’re stranded on a desert island, sending a bottled message may reach people far away, just not very quickly.

The longest known single journey was that of a Doctor Who postcard in a bottle, thrown into the sea at Tyne and Wear in 2011. This turned up 17 months later in Perth, Western Australia – over 14,500km away. But in 1929, German marine scientists dropped a bottle into the Indian Ocean with instructions for the finder to report where it washed up and then throw it back. This floated for six years and covered 25,600km!
