VIDEO: What happens when a fireworks factory explodes

The explosion at the pyrotechnics factory in Colombia blew the cameraman off his feet.

While it may have just missed New Year's Eve, the explosion that happened in the small town of Granada outside Bogota on Sunday set off a volley of bangs, pops and whistles that would make anyone 'oooh' and 'aaah'.
