British plumber and inventor Colin Furze is at it again. This time he's made an ice bike. That's a bicycle with wheels made from rounded blocks of ice.
He first tried it out on the street, but the ice didn't last too long. It did a lot better, on a skating rink, and very well on top of a glacier.
If you haven't heard about Furze before, he's known for his inventions that are sometimes ridiculous and insane.
