Explosion for celebration?

Hello!

I heard a loud noise, looked out of the windows, saw these fireworks. I don't know what was the occasion. So naturally I grabbed my camera and took few photos.
These fireworks look nice but sound terrible.
Who thought (for the first time) it's a good idea to use explosives for celebrating something?
