According to videos captured by onlookers and shared on social media, the balloons gradually shed their mirror coating until a white core remains.
While many thought the orbs were giant Christmas bottles that somehow got loose during Storm Claudio, which battered France and the UK this week, they were part of a temporary art installation in central London to promote the music duo’s new album.
The installation, called Four Worlds Set and created by American artist Tom Shannon, was installed on Sunday night and will be on display at St Giles, off Tottenham Court Road, until Saturday.
The footage sparked reactions online that ranged from apparent joy to absolute disbelief for some wrote poems and songs to the tired balls.
🎶 Decorate the streets with big bottles
Watch the spheroids bounce and wobble
Shredded Mylar spill waves
Fa-la-la, la-la-la, la-la-la
All London drivers are afraid
Fa-la-la-la-la, la-la-la-la 🎶 https://t.co/uLDqUq9bXO

For some, the balloons were reminiscent of the 1960s British TV series The Prisoner, which featured a large white balloon named Rover with the power to stop people from moving. Others joked that the scene reminded them of Raiders of the Lost Ark, when Harrison Ford, who plays Indiana Jones, is chased through a tunnel by a giant rock.
“Imagine falling into a giant Indiana Jones-style bottle on the way home and no one would believe you until this video,” wrote a Twitter user. “Life is really weird right now,” wrote another.

For those behind the installation, the news hit harder. Musician Kai Campos, one half of electronic music duo Mount Kimby, said he was “heartbroken” after the wind caused at least two orbs to come loose.
He said the team responsible had “prepared for bad weather and strong winds, but were really unlucky”.
