Super Steady Hands Built This Working V8 Engine From Paper

By Andrew Liszewski on at

The real thing can weigh upwards of 250 kilos, but the V8 engine built by Aliaksei Zholner would barely register on a scale because it’s only slightly larger than a ping-pong ball and made from nothing but paper and glue.

The tiny engine has a piston stroke of just six millimetres and cylinders that are only five-and-a-half millimetres in diameter. The whole thing can be powered manually using a pair of fingers, but it’s even more impressive when connected to a can of compressed air which really gets the little V8 roaring.
