The child liked it very much. I didn't want to leave. Not to say that there are a lot of things, but everything is sticky. The staff is very friendly and helpful.
There are no exhibits here. All objects are rather experimental installations. But here lies the ambiguity. Yes, most have explanatory signs, but the kids are clearly just having fun without delving into the phenomenon that is being demonstrated. Teenagers may be bored, I haven't seen them there.
We bought tickets in advance, but in fact, it seems that it is not a problem to buy at the entrance. At 10 a.m. we were almost alone, when we left at 13 it was already decent, but not a crowd.
