The things people create are fascinating. Check out this video. The artist had trouble with focus because he was so close to this amazingly tiny V8 engine. Watch the entire thing. At the end he hooks it up to a balloon for power and the result just made me smile.
This incredibly crafted machine is created by engineer Aliaksei Zholner from Belarus. He has made many tiny engines and has youtube videos of them at the link. He also has the plans for his 4 cylinder engine available online here. Anyone feel up to a challenge?
