Functional V8 Engine
This man created a scale to size V8 Engine and that`s not even the cool part. The cool part is that the V8 Engine is almost entirely made out of paper, from the pistons to the throttle and it’s fully functional.
This tiny V8 is small enough to fit in your hand, with a piston stroke of just 6mm and cylinders with a 5.5mm diameter. It doesn’t actually run on gas. The whole thing can be powered manually using your fingers, but it’s more impressive when connected to a can of compressed air which really gets the little V8 Engine roaring.
