On a brisk January day, Racine, Wisconsin, became the stage for an exhilarating competition that brought together some of the nation's most agile cup stackers. The event, known as the Wisconsin Winter Stack Up, took place at Olympia Brown Elementary School, drawing over 100 participants from various age groups. These competitors, including members of Team Wisconsin and Team USA, raced against time to stack and unstack specially designed cups in predetermined patterns. The tournament aimed to qualify participants for the junior Olympics while providing an opportunity to set state and even world records. This year marked the second edition of the event, which is sanctioned by the World Sport Stacking Association.

Sport stacking, a discipline where speed and precision are paramount, involves stacking cups in specific sequences. According to Lisa Berman, director of USA Sport Stacking, this activity not only challenges participants' dexterity but also enhances their hand-eye coordination and reaction times. Participants like Tom Johnston, who enjoys running, find stacking appealing because it mirrors his passion for improving personal bests. "It's all about getting faster," he remarked, highlighting the addictive nature of the sport.

The roots of sport stacking trace back to the early 1980s, gaining widespread recognition after a feature on "The Tonight Show Starring Johnny Carson" in 1990. Since then, the activity has expanded globally, with competitions held in thousands of schools and clubs across 54 countries. A study by Dr. Brian Udermann from the University of Wisconsin-La Crosse revealed that sport stacking can improve bilateral proficiency, enhancing awareness, focus, creativity, and rhythm. Additionally, the sequencing and patterning elements of the sport contribute to better reading and math skills.

Beyond the physical benefits, sport stacking fosters camaraderie among participants. Johnston noted how the sport has allowed him to form lasting friendships, even connecting with individuals from around the world. As the event concluded, it was clear that the Wisconsin Winter Stack Up not only showcased remarkable athletic talent but also underscored the broader impact of sport stacking on personal development and community building.
