Surprisingly the World’s strongest artificial tornado is in the Mercedes-Benz museum in Stuttgart, Germany. It’s even a official Guinness World Record. However the purpose of the 34.4 meter high (112.86 ft) artificial tornado may surprise you.

The architecture of the Mercedes-Benz Museum (designed by UNStudio) placed particular demands on construction planners, architects and engineers with regard to smoke elimination. In the event of fire, 144 outlets located along the core walls inject air into the interior courtyard of the Mercedes-Benz Museum. This generates an artificial tornado, and the smoke collected is then discharged into the outside air via a smoke elimination ventilator located in the upper part of the building. Pretty Cool!
