Today I had to be at school at eight, because we went to Tartu. Tartu is three hours driving away. First when we arrived at Tartu observatoorium. There we first had a tour and we got to see what the observatory look like. There is also a little museum. The museum has a miniature model of the mars surface and old computers. When we watched the observatorium, we went to the main building. There was little rocks made the 

Milky way. After the observatorium we went to Ahhaa center, it was like Finnis heureka. When we got there, we got food. After food someone, ahhaa worker, does science theater for our group. Before there we were divided into three groups. One group at a time goes to explore Ahhaa, this time other groups have free time and they have explained to the science center for free. About twenty over six we have to go back to Tallinn. During my travels I play uno with a few Estonian and Finnish people. It was a nice day.
