We started out at the Museum for Criminology at the police headquarter in Frankfurt. The museum is normally not open to the public (though you can arrange for guided tours), so it was something you don't see normally. There was a demonstration of the the K-9 unit every hour in front of the building. Though I didn't understand a word of whatever the guy who guided the demonstation, it was still quite interesting.
The musuem always has been one of my favorites in Frankfurt and I've been there a couple of times before, but it was new to M.
Inside they had a Mad Scientist Quizshow and a couple of interesting demonstrations.
Next stop was the Experiminta, a Science musuem, with tons of interesting stuff going on.
Our feet hurt and it was very cold.
Still, I quite enjoyed the whole event.
