About Baton twirling
Baton twirling is a sport that combines dance and color guard to create coordinated routines. Instead of such implements as a flag, rifle, sabre, or other props, it requires a "baton" which is a metal rod, typically just slightly larger than one's dominant arm. The sport can be seen in national and international competitions including the USA Junior Olympics.
