I went to Sapporo science center for the first time in more than 20 years. The planetarium in it re-opened in this April after introducing new equipment. The latest projector is used in the planetarium and the view of sky is so beautiful! I enjoyed it among children. Some of children were so excited that they screamed during the program.
When I was a child, my most favorite display was the cockpit of subway train. It still has been there, but this type of subway train has retired few years ago in fact.
We can conduct many experiments here. When I was a child, I enjoyed it, but I couldn’t understand the mechanisms and logic of these experiments. After I've grown up, it is still complicated for me, a little. Anyway, it is good to enjoy some scientific matters, from time to time.
