With 2,433 participants of all ages the event topped the leader board, beating China, who held a similar experiment in June but reached only 2,175 erupting Mentos and soda geysers.
The experiment involves dropping a packet of Mentos sweets into a 2-litre bottle of fizzy drink, causing the liquid to shoot up to two meters into the air.
A Guinness World Records adjudicator was present Saturday to confirm a new mark being set.
"It was great, everyone was excited and they could tell they were here and they wanted to be a part of history and once all those fountains erupted it was just incredible to see," Mike Janela said.
Despite the difficulties of organizing a crowd of nearly 2,500 people to all drop the Mentos simultaneously into the bottle, event organisers managed to get enough people to beat the record. Most participants were left drenched.
