A container filled with millions of Lego pieces fell into the sea off Cornwall, UK, in 1997. They are still washing up on Cornish beaches today offering an insight into the mysterious world of oceans and tides.

On 13 February 1997, the container ship Tokio Express was hit by a wave described by its captain as a "once in a 100year phenomenon”.

As a result, 62 containers were lost overboard about 20 miles off Land's End and one of them was filled with nearly 4.8m pieces of Lego, bound for New York. Shortly after that some of those Lego pieces began washing up in both the north and south coasts of Cornwall. They're still coming in today.
