A competition that involves a lot of plastic cups and some very fast moves took place this weekend as more than 700 kids were in Denver for the World Sport Stacking Championships. Some came from as far away as South Africa for a chance to see how they 'stack' up against the competition.

Cup stacking began at a Boys and Girls Club in California, then gained national attention after an appearance on "The Tonight Show." The competition continued Sunday in Denver.
