'Bubbleologist' Samsam Bubbleman created the giant ball of air using a top-secret mixture he has developed over 20 years.
And the professional bubble-maker, described as ‘the Willy Wonka of Bubbles’ by DJ Chris Evans, is certain his latest attempt will beat the current Guinness World Record holder, which was set in October 2005 in Minnesota, USA, with a volume of 105.4ft.

Resembling something out of 90's hit movie The Abyss, Samsam's incredible creation floated above Finsbury Park, London.
The 37-year-old, who has made bubbles for celebrities across the world, is now waiting for the amazing achievement to be officiated.
"I'm confident it has obliterated the former record," he said. "This one dwarfs the American effort."
To make this enormous orb he used just a piece of rope attached between two sticks.

"It's all about having the right bubble solution," said Samsam. "If you have the right mixture then your tools don't matter.
"Being a bubbleologist is almost as much about being a wind catcher as it is a bubble maker. You become quite sensitive to changes in direction and you have to move at the right time to keep the bubble together."
Once confirmed the new record will add to Samson’s tally of two standing world firsts.
In November 2007 he managed to place 50 people inside one of his bubbles. A year later he earned the award for putting the most bubbles inside a bubble - 66.

Samsam - real name Sam Heath- first started his love affair with bubbles in 1989 and now earns a living doing what he loves best.
"It all started with just a single bubble," he said. "I was sitting in a field and a bubble just floated past.
"I took the word away from the object and just looked at it for what it was. I captured my imagination and I just thought what an amazing thing that was.
"It's like one of those anomalies of nature that just shouldn't exist. Like a bumblebee being too big for it's wings."
He eventually formed company Bubbleinc and now sells mixtures, equipment and performs shows for big name audiences.
Over the years he and his team of 10 bubbleologists have performed bubble shows for the Dubai Royal family.
Stars like Paul McCartney and Peter Gabriel have also brought him in for private shows.
And it's not just shows that people are getting in touch for. Tory leader David Cameron, DJ Norman Cook and singer Michael Stipe have all used his website to buy bubble-making equipment and mixtures
