This is what fireworks do when you fire them inside your living room

Dumt & Farligt (Stupid & Dangerous) is a Danish TV program that really lives up to its name: They do lots of dumb and hazardous things while filming using a Phantom camera in slow motion. Like firing big fireworks in a living room, burning all the furniture in the process.

You can go to the two minute mark, when the firework action starts, but I recommend against it because the entire compilation is worth watching.
