Kids gathered at the White House to kick off an attempt to break a Guinness World Record for the most people doing jumping jacks in one 24-hour period.
First Lady Michelle Obama led the White House jump event.
Sponsored by National Geographic Kids, more than 20,000 people around the world are needed to do the jumping jacks.
Jumpers had to jump for one full minute.
The time period ended at 3pm Eastern Time October 12th, and it will take a few weeks for Guinness officials to verify the official record.
