Tom Tits Experiment, Science museum in Södertälje, Sweden

Tom Tits Experiment is a science centre on Storgatan in Södertälje, housed in four floors of the former Svenska Centrifug industrial building, a red brick structure with a tall peaked grey metal roof. Its roughly 500 experiments cover technology, physics, mathematics, biology, the human body and illusions, with about 6,000 m² indoors and a 9,000 m² seasonal experiment park outside.

The facility first appeared as a temporary exhibition in 1985 before finding a permanent home in spaces of a former industrial company. This transformation of factory space into a learning center shows how old buildings can serve new purposes.

The place reflects the region's industrial past and shows how scientific curiosity brings people of all ages together. Visitors experience how science works in everyday life and are encouraged to experiment for themselves.

Indoor experiments fill about 6,000 square metres over four floors, while the 9,000-square-metre experiment park opens only in summer. The spiral tube slide about 40 metres long runs down the outside of the building. Allow time for hands-on stations on each level.

The outdoor park holds an industrial robot fitted with a two-seat sofa, programmed for five different rides and rated for 500 kg. Nearby, the "Självfallet" attraction lets visitors fall freely from a height of 15 metres. The park is open in summer.
