Some 55,000 firework rockets lit up the night skies above Plymouth on Wednesday night in a noisy world record attempt.
The explosion above Plymouth Sound in Devon was watched by 50,000 people.
The monster bang was set up by Dr Roy Lowry from the University of Plymouth to mark the 10th anniversary of the British Firework Championships.
To get the record, all the bangers had to go off in five seconds. Experts are now checking film of the event to decide if the record has been broken.
The current record is 39,210 rockets set off by Terry McDonald in the Channel Island of Jersey in 1997.
The Fireworks Championship also saw eight people going for the title of British Firework Champion of Champions.
The winner was a display by Jubilee Fireworks.
