Hundreds of people took part in a world’s record-breaking event at the Iowa State Fair on Sunday afternoon. The fairgrounds’ grand concourse in Des Moines was filled with just over 1,500 people, all in red t-shirts, taking part in the “Stop, Drop and Roll” fire safety demonstration — the largest ever.

Iowa Hawkeyes’ sportscaster Gary Dolphin emceed as everyone simultaneously performed the maneuver you’re to go through if you’re exposed to fire. It’s expected to take a few weeks before Guinness officals verify the new world’s record. The current record involved about 600 people in Indiana.

The Iowa event had 1,519.
