With the help of 234 students at Eisenhower Elementary School, a new Guinness World Record has been set for most people sport stacking at multiple locations in one day. The new mark is 483,658, besting last year’s record by more than 70,000 stackers. According to the World Sport Stacking Association, the 2012 record was set by 2,375 schools and youth organizations representing 30 countries from around the world. To be counted, each stacker was required to engage in sport stacking and related fitness activities for at least 30 minutes on Guinness World Records Day Nov. 15.
