To celebrate the opening of Legoland Water Park, 1355 guests simultaneously threw beach balls into the air - setting the new world record for the most beach balls in the air simultaneously.
The previous Guinness world record stood at 401, but the 1,355 special guests, who also got to sample the water park before its official opening, smashed the figure.
Guinness World Records also recognized the world record for the most balls released simultaneously: 10,000-at the Mega Pic-Nic 2010 organized by Realizar Eventos Especiais and Modelo in Parque Eduardo VII, Lisbon, Portugal.
This record-setting attempt was held during the media preview of Legoland Water Park at Legoland Florida in Winter Haven.
As the crowd was given the signal, the sky turned into a rainbow of reds, whites, blues, yellows and greens.
Adrian Jones, general manager of Legoland Florida, called it "incredible."
"We announced we were going to do this ridiculous stunt to let people in but we had over 1,300 people turn up," Jones said. "Some of them were here half past 10 last night and camped out and we've just broken a world record.
Guest were allowed to keep the beach balls.
A "park within a park," the attraction includes Build-A-Raft River, where guests can build their own LEGO inner tubes and float down a 1,000-foot lazy river.
For the little ones, the DUPLOŽ Splash Safari is a toddler haven with perfectly sized slides a zero-depth wading pool.
Guests of all ages can play for hours at the Joker Soaker water playground, a riot of brightly colored ladders, levers, pumps and slides of every length and type.
And a 583,000-gallon, crystal-clear wave pool and five slippery-fast water slides will thrill families all day long.
Admission to the water park will be a $12 add-on to the price of a regular ticket. To find out what kind of fun the new water park is offering, go to www.legoland.com.
