YouTuber Master Milo turns an old Ford Ka into a rolling, spinning, amusement park ride-like “diwheel” he calls “the RollKa.” Master Milo took an otherwise lackluster economy car, chopped it in half, and mated it to two large, parallel wheels. The wheels on the Ford Ka spin and make traction within the tracks of the larger fabricated ring wheels to move the ungainly body around.

I love watching these kinds of videos. I have zero mechanical ability or imagination but I’m always fascinated by those who do.
