A massive explosion of almost 57,000 firework rockets has been crowned officially as a world record.
The noisy display lit up the sky above Plymouth Sound in Devon in August, but it took experts three months to check.
To get the record, all the bangers had to go off in five seconds so a film of the explosion was made.
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.
Dr Lowry said: "I am really pleased, not least for all those people who helped load the rockets."
The record bid took over a year to create and used 250 kilos of gunpowder, the equivalent of a tonne of fireworks.
He was given the 56,649 rockets and they were loaded into specially made frames by a team of about 50 people.
The previous was 39,210 rockets set off by Terry McDonald in the Channel Island of Jersey in 1997.
