What a cool little place we stumbled upon. After being in Madrid for only about a week, my son spotted this from across the mall (btw, it's inside the ABC Mall on the third floor off Serrano street).
The entire museum is small but filled with cool little items and trinkets. About a quarter of the museum is free to the public but to see the rest of it, which is the tour portion and the hands-on items, you need a ticket (see pictures for price list). Be warned, the entire tour is interesting but it is only in Spanish. The hands-on portion was extremely fun for the kids but the time is limited.
The overall consensus from the family was, and I quote, "really cool." My son would go again and again. However, for parents it's kind of a one and done thing unless you are into robotics. Nevertheless, go and enjoy. read more
