This is one thing that you’ve definitely got to see. In Germany, in the Mercedes-Benz Museum in Stuttgart, they can repurpose the building’s internal ventilation system to create an artificial tornado – indoors!
This twister takes about 7 minutes to form and is powered by 144 jets and 28 tons of air. The system was initially created to funnel away smoke from inside the museum to the ventilation shaft and the outside world.
The whole thing is more than 100′ tall, making it officially the world’s largest artificial tornado, which is not likely to be a very crowded category in the Guinness Book, is it?
