Orinda's Del Rey Elementary School received official word that they earned a Guinness World Record after 402 students completed a five-minute choreographed school-wide hula hoop workout March 25. The hula hoops were donated to Community Education Project which provides equipment to underprivileged schools throughout the Bay Area. As the Guinness website says, that's "Officially Amazing!"
