Some 600 people on spacehoppers have taken part in the world's largest simultaneous hop.
The record attempt took place on the Millennium Bridge
They took part in a Guinness World Record attempt to hop together for a minute on London's Millennium Bridge - famous for its initial wobbles.
They beat the previous record, set by 551 spacehoppers in Bath in 2003, Guinness World Records has confirmed.
"The bridge was pretty bouncy under all those people," said an event spokesman. "I think we thoroughly tested it."
An adjudicator from Guinness World Records was at hand to certify the new world record.
The previous record had been held by pupils and parents at St Stephen's School in Bath.
UKTV Gold staged the bid to mark the new look of the channel.
