BBC News published this video item, entitled “Giant concrete dominoes fall to start UK festival – BBC News” – below is their description.
More than 7,000 concrete dominoes have fallen to start the 250th Norfolk and Norwich Festival.
The dominoes stretched between Anglia Square and The Forum in Norwich, with some even going through homes and buildings.
Artist Julian Maynard Smith said the artwork, which has been replicated across cities of the world since 2009, grew out of an initial idea to connect boroughs of London.
Each concrete domino weighed about 17lbs (8kg). The 1.6-mile (2.5km) toppling lasted about 30 minutes.BBC News YouTube Channel
