There are enough interactive exhibits to engage kids, but it's not a US-style science center that's entirely for kids; there's much more informational displays that adults can learn a lot from.

Who knew I'd be interested in European train coupling or the evolution of domestic cleanliness?
Where at all possible, content is local, so the museum has a strong sense of place. For example, there's some depth around how Austria specifically generates & distributes electricity, and the Vienna Airport growth is a case study in transportation challenges.
To explore everything in the museum could take 4 hours; 2 hours would be a more manageable visit. As you get further from the center core, some of the less-visited exhibits could be skipped, unless you have a particular interest in for example printing presses.
