"Rubber Ducky, You're the One"
"The ducks fell overboard from a container ship off the Alaskan coast during a storm in 1992. Then the ducks - along with lots of other plastic frogs and turtles - set off on a long journey through three oceans.
It's thought they were trapped by slow moving ice for several years - it took them until 2000 to reach Iceland. A year later, they reached the area of the north Atlantic where the Titanic sank.
During their voyage, some of the ducks broke away - and headed for Europe. Others have surfaced in Hawaii. Scientists have tracked them throughout their long journey, and they say it's taught them valuable lessons about the way that ocean waters move around.
