The smallest engine in the world made entirely out of paper with a software engine.

The tiny single-cylinder engine, complete with a throttle, runs on air from an attached balloon. This contraption is about the size of a thumbnail and has a piston stroke of 3 millimeters, Daily Mail reports.

The creator of this miniature piece of machinery, Aliaskei Zholner, created the machinery just 18 mm long, 13 mm wide and 22 mm wide, with a shaft diameter of 0.5 mm.

Single-cylinder engines are often seen on motorcycles, motor scooters, mopeds, dirt bikes, go-karts and is used in many portable tools – they are also constructed with metals like steel, cast iron, and aluminum but this one won’t be used for anything other than a showpiece.

The miniature engine is designed with a small crank on the side to power it manually, but Zholner hooks it up to a balloon and uses a throttle to control the air flow.
