Fireworks

They really like fireworks here in Brasilia!
I have been here two weeks now and can't even count how many fireworks I have heard. I haven't seen any though. As my apartment doesn't really have any windows and now view at all, I don't see anything but I hear.
Here they also seem to like having fireworks accompanying their demonstrations. That means you hear fireworks also at daytime, which seems like a waste as you will hardly see anything of it.
