Crazy DIY inventor Colin Furze is back again with another ridiculously insane (and dangerous) new invention.

Having already won the Internet multiple times with his Wolverine claws, Magneto shoes and the world's fastest baby stroller, Furze recently turned his attention to creating a jet-kart — a jet engine strapped to a go kart.

As you can see in the video above, the jet kart looks bananas and looks like something straight out of Mario Kart with flames shooting out of the tailpipes.

The "most mental kart ever" — as Furze calls it — runs on diesel and gas, and is capable of hitting a top speed of 60 miles per hour. Furze admits it could be faster, but he wasn't able to test the claim because he didn't have enough airstrip to race it on. Oh, Furze, you crazy nutter.

This isn't the first time Furze has strapped a jet engine to vehicle with wheels. Back in 2013, he made a jet bike.

One suggestion we have for Furze: Wear a damn helmet. You want to keep making crazy inventions, right?
