If your fog smells like rotten eggs, that might not be fog!

One evening, a strange fog began rolling over this South Korean neighborhood. While few were around to see it, those who did noticed that there was something off about it. Since when does fog roll out like that? And why does it feel explode-y?

As it turns out, that’s because it was about to explode!

According to the New York Post, the blaze lasted about three hours before the Gangwon Fire Department managed to stop it. In total, the blast damaged 14 buildings, caused 25 people to evacuate and resulted in five being injured, though thankfully no one died, somehow.
