One of the biggest museums of Germany. It's focused on science and technology with lots of materials and triable models. Every scientist, every student, every engineer must visit the museum. Don't forget to spare a few days, because it's impossible to take a tour in a day. If you are hungry about knowledge, you must visit every exhibitions in different days. - Mücahit Yılmaz from Bookmarklet

I'm glad to have this chance in the past, we spend about 50 hours with my (geography proffessor) dad at there. - Mücahit Yılmaz

@vadi I've also visited 10 years ago (actually in 1997 and 1999 summers) and I was 12 years old, Also I was fascinated too much :)) My father has 3000 photos from the museum. And I don't forget the water canal system. I've experienced to manage a canal and that was amazing when I was 12.. I want to visit again.. - Mücahit Yılmaz

I reminded me of Rahmi Koç Museum but of course a much much larger scale one :) - ipek aral kişioğlu
