Though they sound like something straight out of an action movie, a fire tornado is actually a real thing that can be found in nature. This one, though, was created by the Slow Mo Guys -- but that doesn't mean it looks any less epic.
The controlled, manmade twister was created by setting up 12 box fans in a circle and lighting a kerosene fire in the middle. The fire tornado looks badass as is, but when they slow the camera down, this insane column of heat really comes to life. See the footage -- both in slow mo and in real time -- below.
Watch how the Slow Mo guys turned a ball into a spiral galaxy.
