The Powerhouse Museum is Sydney's Design and Science museum. Fun for kids that like exploring, costructing (and trains). There are always children's activities, and this time the interactive workshop Oikodome, Building architects, constructing geometric shapes with cardboard rolls. Students in architecture were there to guide children above 5 on how. Locomotive No. 1, first train in NSW. In the museum coffee shop, The babychino finished! Inspired by the exhibitions we buy a little airplane. It's another brand than Lego and the pieces do not stay together... and causes much frustration. And how does jet engines work?
