This video of a homemade fire tornado is totally mesmerising

Daniel Gruchy and Gavin Free, or “The Slow Mo Guys,” are known on YouTube for filming crazy stunts.

And their latest stunt  — making a giant, swirling vortex of flames out of household objects — is no exception. 

Using 12 electric fans, the pair created a fire tornado. In case you’re not familiar, fire tornadoes are a rare but naturally occurring phenomenon. They are shaped like a typical tornado, with just one noticeable difference: they’re made of giant flames. 

Here’s a look at a real fire tornado that swept through Brazil in 2010.

And here’s how Gruchy and Free made theirs. They started by lighting a fire using kerosene. 

The pair let the fire grow before turning on the fans. 

And finally, here’s a slow-motion look at their creation, which reached over ten feet height. 

“It’s very hypnotic,” commented one Redditor about the mesmerising video. “I can’t stop watching.”
