Mud and electricity

I learned how to jump a car today:

First you clamp to the positive electrode of the running car. Next you clamp to the positive electrode of the dead car. Then you clamp to the negative electrode of the running car. Finally, you attach the remaining clamp to the dead car's frame as a ground. Then you try to start it.

Thank you, kind soccer mom and most awesome soccer team ever (that would be mine)! It was rainy and muddy today, but we had fun :)
