What is the world record for biggest balloon?

As of my last update, the world record for the largest balloon was set by a team in Italy in 2016, with a balloon measuring 32.5 meters (106 feet) in diameter. This massive balloon was created for a festival in the town of L'Aquila. However, records may change, so it's advisable to check the latest information from official sources like Guinness World Records for the most current record.
