Londoners have been treated to the world’s first “multi-sensory” fireworks display as people around the world welcomed in the New Year.
More than 250,000 people lined the Thames for the display, which saw peach snow and orange-scented bubbles descend on a section of the crowd.
In Scotland, about 80,000 were in Edinburgh city centre for the famous Hogmanay street party.
There was music from the Pet Shop Boys as well as traditional Scottish sounds at an outdoor dance event.
But those venturing outside to welcome in 2014 were contending with some horrible weather – with the Met Office issuing more than 100 flood alerts.
Spectators in London said the show was the best ever.
Harriet Dudley, from Brighton, said: “This was the best ever show and I’m so glad I came to watch – I feel so emotional. It was, like, four-dimensional.”
Referring to London’s show, Mayor Boris Johnson said: “There is no better way to celebrate the highs of 2013 and the start of an exciting new year than by seeing one of the world’s most dazzling firework displays, now augmented in more ways than one.”
“Watched by millions around the world, and hundreds of thousands of people from the banks of the Thames, it highlights our capital’s fantastic community spirit and its premier position on the global stage.”
Up to 100,000 people in key viewing areas by the Thames were given packs featuring scratch ‘n’ sniff programmes and LED wristbands.
They also had seven kinds of fruit-flavoured sweets that linked to the tastes and smells of the multi-sensory display.
The UK celebrations were among displays from around the world including the largest ever fireworks display in Dubai.
The six-minute extravaganza included 500,000 fireworks from 400 firing locations, all synchronised by 100 computers from stations across the city.
Later, there will be a celebration parade in London which features music from around the globe.
It leaves from the Ritz Hotel at noon before winding through Piccadilly, Pall Mall and Trafalgar Square and ending in Parliament Square.
About half a million people are expected to attend.
