Artificial fire tornado filmed at super-slow speed

LONDON, Nov. 23 (UPI) -- A pair of British YouTubers specializing in slow-motion stunts shared video of an artificially-created fire tornado slowed to 2,500 frames per second.

Gavin Free and Daniel Gruchy, aka The Slow Mo Guys, posted a video to YouTube featuring a simulated version of "the most interesting natural disaster," a fire tornado.

The duo used a fire pit filled with a half an inch of kerosene to start their fire and surrounded the flames with 12 box fans to simulate the wind conditions.

The result was a miniature fire tornado, which they filmed using a 2,500 fps camera and a 1,000 fps camera to showcase the spirals in slow motion.

A natural "firenado" was caught on camera at Idaho's Soda Fire in August, and footage of a famous fire tornado resulting from a bourbon spill at a Jim Beam warehouse in Kentucky was released earlier this year.
