YouTuber creates 20-foot tornado fire that's as mesmerizing as it is dangerous

Playing with fire is probably not the best idea, but what if you do it in a super cool way? Like make a giant 20-foot tall spiral of flames trapped inside a huge metal cage that spins around continuously?

Well if you had that idea, sorry, it's already been taken by Colin Furze, a "British garage inventor/video maker." The Youtuber has already amazed the internet with a number of mad scientist creations, like a homemade hoverbike, a giant Star Wars AT-ACT garden den, and, of course, fully automated claws inspired by X-Men's Wolverine.

His newest wonder -- that awe-inspiring tornado fire which could be the largest ever built by a human -- was put together using a go-kart and a 20-foot cage. The go-kart spins the cage around while a bunch of fireworks at the top make the whole thing even more spectacular.

You kind of have to see it to believe it.

But Furze might not want to light that flame again ... or at least Smokey Bear probably wouldn't recommend it.
