Hundreds of Palo Alto elementary students Wednesday sprang into action in support of first lady Michelle Obama's bid to set a Guinness World Record for jumping jacks.
Led by third-grade teacher Penelope Sanders-Jones, who stood on the roof of the school, students at Fairmeadow Elementary School formed lines on the playground and did jumping jacks for a full minute during their morning recess.
The goal was to break the Guinness World Record for the most people doing jumping jacks in a 24-hour period.
Jumper-in-chief Obama led the charge Tuesday, assembling 400 Washington D.C.-area schoolchildren to join her in a minute of jumping jacks on the south lawn of the White House.
More than 20,000 people were needed to break the record, according to National Geographic Kids magazine, which promoted the event. In the end, Fairmeadow contributed 271 to the count, which was officially documented by more than a dozen independent volunteer "witnesses" who have no connection to Fairmeadow.
The event was part of Obama's Let's Move campaign, aimed at solving childhood obesity within a generation.
"The physical and emotional health of an entire generation and the economic health and security of our nation is at stake," Obama said at the time the campaign was launched in February 2010.
