How can I build a car that will run without me pushing to start?

I have a project to do where I must build a car without pushing it to start. I can wind, blow, etc. on something that will make the car go. The only thing not allowed is pushing the actual car with my hand. Any ideas?

Yeah, I'd give it an electric or combustion engine.
