How fast could your Christmas tree go up in flames?

Dublin Fire Brigade have tweeted a special fire safety video for the festive season.
The video is from the NFPA which is self-described as "the leading information and knowledge resource on fire, electrical and related hazards."
The video shows the difference between how a dry tree and a well-watered tree burns.
The dry Christmas tree burns significantly faster than the well-watered tree and after just 18 seconds it is almost completely engulfed in flames.
