This V12 engine is made completely out of paper. What’s even cooler is that once you watch the video, it not only is fully moving, but the combustion chambers even “spark”. (OK, maybe its not 100% made out of paper). The LEDs are powered by 2 AA batteries. This unique piece of art was created by a Canadian designer named Yee. Just Yee.
i always prefer to use brushless cooling fans because they last longer and needs less maintennance..*
