RE: Is Water a Fuel? Well No, But Actually Yes. Sort Of?

You just need a 5m rope. You tie it to the back of your car, reverse over it, and tie the other end to the front.
Pull on it really hard until the car starts rolling, then quickly jump in the driver's seat and tow yourself wherever you need to go.
In a pinch, you can double up the effect by running a second rope over the top of the car; but that kind of pressure can buckle the roof or even crack the windscreen.
