The crazy inventor Colin Furze shows us a paranoid (and dangerous) new invention. Furze built a jet-kart – a jet-powered go-kart. As you can see in the video, the karts seem pretty funny and reminds of something from the video game Mario Kart, with flames to be ejected from the exhausts. The Karting operates on diesel and gas, and can reach 100 km per hour. The Furze admits he could be much faster, but he didn't have the necessary space to try it.
