“The twister takes around seven minutes to materialize,” Autoblog explains, “and is generated by 144 jets and 28 tons of air. The low pressure area at the center of the tornado works to create a jet stream that draws smoke out of the building’s corridors and funnels it upwards and out an exhaust vent on the roof.” It is also more than 100 feet tall—making it the official world-record holder for the World’s Largest Artificial Tornado.
