The Firecrackers - King County School District, Ohio

From Website:

The Firecrackers are a team of elementary and junior high school girls from Ohio. This demonstration was at halftime of an Army/ Navy basketball game. Both sides gave the girls a standing ovation, and then some.

The girls practice for 2 hours a day, 5 days a week, and they have to keep their grades up too. And each girl must pass an etiquette class before joining the team. Enjoy.
