As I mentioned a long time ago, a lot of fireworks happen at various occasions in Berlin. Yesterday, when I arrived at east downtown, another one was starting right away. Obviously unexpected by the other Berliners too because hardly anybody was there to watch it. People were apparently surprised to watch such a gigantic fireworks with a lot of never-seen-before effects. The sollution: At the moment the International Symposium on Fireworks is happening in Berlin and this fireworks behind the Brandenburg Gate was presented by Weco, one of the big companies in that field. Seems to me that they wanted to present their new innovations. Anyways, a nice surprise to us, the people who were able to watch it.
