A short walk from Darling Harbour, this science and design museum whirs away inside the former power station for Sydney’s defunct, original tram network. High-voltage interactive demonstrations wow school groups with the low-down on how lightning strikes, magnets grab and engines growl. It's a huge hit with kids but equally popular with adults, touching on subjects such as fashion and furniture design.
Grab a map of the museum once you're inside. Disabled access is good.
