br A terrifying moment for Canadian firefighters was caught on video last month when a 200-foot-tall fire tornado literally sucked a hose into the sky and then melted it before their eyes. “Fire tornado destroyed our line,” wrote Instagram user M.C. “It threw burning logs across our guard for 45 minutes and pulled our hose 100 plus ft. in the air before melting it. That’s definitely a first.” Fire tornadoes are caused by a dangerous mix of heat and wind, which can then start to rotate like a tornado.
