You may never have seen so tiny and fully functional engine made out of paper before. Aliaksei Zholner is the talented guy who built this tiny functional V-8 engine that runs on just compressed air. Even though its paper, still sounds better than a ford. He should probably make different sized motors like v6 i6 i4 v10 a boxer and a v12, and see if they sound any different. And then move onto making a fully functional paper car.
