About 450 Mountain View Elementary students were doing jumping jacks simultaneously on Tuesday. Their effort was part of an attempt to break the Guinness World Record of Most People Doing Jumping Jacks In a 24-hour Time Period. The current record is 20,425.
"We do jumping jacks as part of our physical routine all the time," Mountain View gym teacher Rob Dimick said. "It's nice to be take what we do in class and compete and try to break the world record too."
