speed stacking

Thomas Mann practices stacking upside down plastic cups upward in a pyramid shape. Then he unstacks them. Quickness in each direction and improving his times are the goals. The 11-year-old has only been cup stacking since early 2017, learning most of his technique from watching on YouTube. At the Mann home in south Lubbock, the hollow, rapid kerplunking sound coming from Thomas’ bedroom is a regular happening.
