An ambitious art installation ended up creating a chaotic spectacle when it relentlessly drenched a worker in rainbow-coloured foam.
Island of Foam: Version XVIII by German artist Stephanie Luening had been installed to 'mesmerise' onlookers and ' transform' the Greenwich Peninsula surrounding the O2 Arena in London by sending mountains of coloured liquid through the streets.
But a gust of wind turned the entire display into a foam frenzy after it suddenly began blowing the other way, causing one woman working the machine to face an onslaught thought to have lasted at least 20 minutes.
Footage showed her resolutely standing still in the same spot despite being walloped by the rainbow-coloured foam, drawing shock and admiration from those who watched on
.
The woman, who has not been named, came to take a bow at the end along with the artist.
Tom Davis, a student living in London, saw the incident unfold while shopping and said: "It wasn't really windy when it started.
"The foam was going down these stairs, and then all of a sudden, after like, five seconds it all started going backwards.
"It lasted about twenty minutes, maybe a bit more, and this woman was stuck under the foam the whole time."
Tom said the woman appeared to be in charge for changing the colours of the foam, meaning that she couldn't move at all.
"When she arrived she was dressed really smart, like she was going out for the afternoon, smart casual, and when she left she was just completely drenched."
He added that she quickly became the "main character" of the attraction in the eyes of onlookers, despite the fact she "obviously didn't know what she was in for".
The installation took place by the O2 arena on August 3 as part of the Greenwich & Docklands International Festival.
