Can you do jumping jacks for a minute? Would you like to be part of a world record?

If you answered “of course” to both those questions, then you might want to be part of an attempt led by National Geographic Kids magazine and first lady Michelle Obama to set the world record for the most people doing jumping jacks in 24 hours.

The event kicks off at 3 p.m. on October 11, when Mrs. Obama will lead a group of Washington area kids in jumping jacks at the White House. But the idea is to get kids everywhere up and jumping for just one minute sometime between 3 p.m. October 11 and 3 p.m. October 12. More than 20,000 people need to participate to set the record. “Grab your parents, teachers, classmates and friends, and help us break the Guinness world record for jumping jacks,” said National Geographic’s Melina Bellows.

There are some rules for participating, so get a grown-up to go to kidsblogs.nationalgeographic.
and get ready to jump!
