Originally, the record attempt was going to involve only the fourth- and fifth-graders who had physical education on record day, Thursday, Nov. 14. But the speed-stacking unit proved to be such a hit that Giribaldi opened the experience up to every South student in fourth and fifth grade.
Last Thursday, South’s 184 speed-stackers joined, at last count, 500,781 stackers at 2,828 schools in 33 countries in shattering the previous one-day world stacking record of 483,658 stackers, which had been set the previous year.
Giribaldi credited the Andover Fund for Education for providing a grant to buy the speed-stacking cups last year and the South PTO with purchasing the mats and timers. He said other schools in town, including Shawsheen Elementary and Andover High, have used the cups as educational tools and to be part of previous world-record attempts.
“They are a great resource for the teachers and students of Andover,” he said.
