Man-Made Tornado in a Museum

The Mercedes-Benz museum in Stuttgart has a bit of an unusual attraction.

The building has the world's most powerful man-made tornado, and whilst this does attract visitors, this is not the reason for its existence.

Created from 144 jets spewing 28 tons of smoke in a 112-foot-high column, the idea of a tornado in a showroom containing over 150 luxury vehicles may seem like an odd one, but it is actually a clever fire-safety mechanism.

The building is made from a steel structure based on a double-helix, featuring a massive central atrium viewable from the floors that spiral around it. All rooms are open, all walls are curved and each of the 1800 triangular window panes on the exterior walls is unique. This however means that there are no fire zones within the building so by creating this tornado they are able to expel smoke emissions from within the building. It is said to take about 7 minutes for the jets that line the interior walls to get the smoke to whirl into a tornado and escape through vents in the roof.
