What comes to mind when I say the word "engine"? Do you image a hulking piece of twisted metal with gasoline running through its veins? Well, one creative YouTuber has engineered a working V8 engine made entirely from paper and scotch tape.
Unlike traditional engines, this origami replica runs on air that is pumped from a balloon. Although it's doubtful that the paper engine could propel much of anything, it has to be seen to be believed.
Watch this video to view the paper V8 motor in action.
