• Science Center Spectrum sits across the museum park with more than 150 experiments; backpacks and large bags are not allowed inside, so use the lockers
• Two to three hours covers the main museum; add Spectrum and a picnic in the park and it fills a day
• Three halls closed for renovation: Photography, Film Technology, and Chemistry and Pharmacy are shut until further notice

A large technology museum with a locomotive shed full of historic trains, a shipping hall where kids hoist sails and steer a boat into harbor, and an aviation wing with the "Candy Bomber" plane up on the roof terrace.

The Science Center Spectrum, on the same ticket, has more than 150 hands-on experiments. Outside, the museum park has a playground and picnic areas.
