Here's how fast a Christmas tree can go up in flames and torch a home

The Sacramento Fire Department conducted a demonstration on how fast a dry Christmas tree can turn into a torch inside home. The video illustrates how important it is to keep a tree watered and away from heat sources such as a space heater. Firefighters ignited the tree Wednesday, Dec. 7, 2016, in a simulated living room. Also, fire officials said, make sure smoke detectors are working.
