As for the second record for the largest number of people inside the bubble, there were some problems. And, mostly, they related to the rules set by the Guinness Book of Records.
They include a lot of technical conditions that must be met. Otherwise, the record is simply not ruled valid. The list of Guinness includes requirements for the premises, the methodology for participants account, the restrictions on the participants' height, the backdrop for the bubble, the procedure of shooting photos and videos, the availability of competent witnesses and a special fenced area, the presence of media… And a lot of other small things that must be provided in advance.
Of course, to meet all the requirements and do everything at the highest level, it took a whole team of people who were not indifferent to my bubble activities.
