This has to be the nightmare scenario for anyone working in the fireworks industry. What happens if your factory catches on fire?

Well, that's exactly what happened in Granada, Columbia on Jan. 4. No word yet on why it exploded -- an investigation is underway.  One person sustained minor injuries. But luckily for us, another guy caught the whole thing on camera.

It's exactly what you would expect, too -- the plant explodes and then just keeps on exploding. Fireworks shoot everywhere, and the cameraman, Nicholas Salcedo Porras, was even knocked right off his feet.
