A Lego brick is able to survive in the ocean for up to 1,300 years.

Research conducted by the University of Plymouth has revealed that the bricks would still exist in some form despite the constant exposure to saltwater.
The study saw researchers collect 50 Lego bricks that had washed ashore in Southwest England and compare their mass to bricks taken from storage.
Their approximate age was estimated using an X-ray to determine which chemical elements were missing.
A rate of deterioration was made based on their condition relative to the stored bricks.
The study revealed that the Lego bricks could on to a semblance of shape for over 1,000 years, although some pieces had decayed into blobs of plastic.
Andrew Turner, who led the study, suggested that the research shows the importance of dispensing with used items in the right way.
He said: ''It once again emphasises the importance of people disposing of used items properly to ensure they do not pose potential problems for the environment.''
