Dozens of colored cups, forming a 3-foot-tall tower, stood in front of the slightly taller Cameron Lowe. The Redcliffe Elementary fifth-grader waits for the signal from student teacher Christina Haupt until he can begin tearing it down – six cups at a time.

At a table to the right, fifth-graders Jessica Matlock and Isiah Coleman try to stack and unstack a set of cups as quickly as possible. Three, then six, then three go up as fast as they go down.

It's all part of an attempt to take down a world record.

All Thursday long, as a part of Guinness World Records Day, schools from across the globe took part in the “World's Largest Sport Stacking Event.”

At Redcliffe Elementary, where they have been stacking cups for two years, students from all grade levels competed to help and try to break the record for “Most People Sport Stacking at Multiple Locations in One Day.” The goal on Thursday was to beat the previous record of 412,259.

“They stack them up and close them down,” Redcliffe physical education teacher Don Osborne said. “The students love it. It's something they can do at home, too.”

Osborne and fellow P.E. teacher Char Dodson introduced their students to cup stacking two years ago.

Sport stacking, according to the World Sport Stacking Association, “is an exciting sport where students up stack and down stack 12 specially designed cups called Speed Stacks in predetermined sequences as fast as they can. Stackers race against the clock, compete in relays and often combine sport stacking with fitness challenges at part of physical education classes.”

“It's real good for large groups in a small area,” Osborne said. He added that it's a great way for kids to work on hand-eye coordination.

According to a WSSA press release, speed stacking is in more than 35,000 schools around the world. Along with the U.S., schools in Hungary, Germany, Isreal, South Africa, New Zealand, Columbia and Taiwan were also working to break the record.

“They're fun,” Coleman said as he finished his hand at the sport. “I like seeing how fast you can go.”

The WSSA website kept track of the numbers being reported from across the world Thursday, but the final numbers were not known by press time.
