This article is about the incredible journey of 29,000 rubber ducks.

The armada of 29,000 plastic yellow ducks, blue turtles and green frogs broke free from a cargo ship 15 years ago.

Since then they have travelled 17,000 miles, floating over the site where the Titanic sank, landing in Hawaii and even spending years frozen in an Arctic ice pack.

And now they are heading straight for Britain. At some point this summer they are expected to be spotted on beaches in South-West England.

The whole thing has actually really assisted oceanographers to map ocean currents because:

when they are spotted bobbing on the waves they are much more likely to be reported to the authorities than the floats which scientists normally use.

And because the toys are made of durable plastic and are sealed watertight, they have been able to survive years adrift at the mercy of the elements.
