London, July 31, 2009--In London's Findbury Park "bubbleologist" Sam Heath—that's Samsam Bubbleman to you—creates what may be the largest free-floating soap bubble in history. The previous largest known bubble, according to Guinness World Records, measured 105.4 cubic feet (3 cubic meters).

Heath is sure he's burst that record, set in Minnesota, though Guinness has yet to formally recognized his feat. "This one," he told Britain's Telegraph newspaper, "dwarfs the American effort."
