SugarBabies, Ellisville

The SugarBabies—a nonprofit girls' baton-twirling team—teaches youngsters the finer points of showmanship during classes that span three levels of expertise. Techniques such as the helicopter and the double-leg roll push the boundaries of physics and require intense coordination, precise execution, and an abiding hatred of Isaac Newton. The artistic nature of this sport gives girls a chance to express themselves creatively, and sharing the experience with other athletes fosters friendships. Once newly minted spinners are up to speed, they can leap into the limelight at any of the SugarBabies events, including appearances at parades, fairs, and theme parks.
