This couch was burned in a safe area out in the country. Do not try this in town or where there is a burn ban. It was burned without any accelerants. It was very old and dry and didn't take long to fully ignite. In fact it got so hot that other debris around it started to ignite. The video was sped up and shows the entire 60 minute video in about 8 minutes. The sounds you hear are olanes flying overhead as we live near a private airport.
