Newton's Third Law In Action

How does Newton's Third relate to this project? Well, Newton's Third Law states that for every action there is an equal and opposite reaction.

The picture on the left shows how this law plays a part in this project.
The green arrow represents the action force, or the air coming out of the balloon. The reaction force (the blue arrow) is the air pushing back with the same force, in the opposite direction, on the balloon.
Because the forces act on different objects, the forces do not balance out.

This is how Newton's Third Law causes the car to start moving.
