We all have that dumb mate who likes to mess around with fireworks. If you haven't got one of those mate, maybe it's because you are that mate.
These folk from Sweden decided one dull frosty morning to liven things up a bit. After all, those short dark winter days in Scandinavia mean you're bound to feel a bit down. So they bought a firework, smashed a hole in an icy lake, light the fuse and..... KABOOM!
We've seen mountain bikers shredding a trail at night with fireworks strapped to their back and this creepy US firework safety video - but this is truly takes firework antics to new levels of idiocy.
Don't try this at home, kids.
