The kid in this video is possibly a secret disguised ninja as she captures the "cup stacking" world record in 7.43 seconds. Who knew there was a cup stacking record anyway. In any event, first she stacks up a large stack in the middle and two small stacks. After breaking those down she stacks two large stacks and breaks them down again. Finally she stacks one extra large stack in the middle. These are plastic drinking cups like you would buy in the store. Super crazy secret ninja or little kid? You decide.
