Momentum
As in balloon-powered rockets, a reduction in energy within the balloon can be accompanied by force exerted to move the balloon, or another object. The energy stored in a balloon is in the form of higher pressure stretching it out. If the balloon has an opening, the air will be forced out until the balloon regains its unstretched shape. At that point, air inside the balloon is at the same pressure as the air outside the balloon. Other containers can also store air at a pressure higher than the outside air. This can also provide force when the stored energy is released.
The magnitude of a buoyant force on a balloon depends on the size of the balloon. In other words, the force will be either big or small depending on the correlating size of the balloon in use with the experiment.
The force in an inflated balloon is exerted outward equally in all directions.
Electrons move between the hair and the balloon.
Momentum
Both a balloon and jet engine exert force in the backward direction to move forward.
force
The more balloons you have, the more the force will be to move forward. So yes. btw there are a lot of balloon car websites. I have just recently made a balloon car myself and won farthest distance.
The balloon expands or even pops. Because when a gas gains heat energy the particles in it move faster and further apart creating a greater force on the inside of the balloon until the balloon cannot contain that force.
the pressure in side the balloon will get squizz out and make the air move

If the forces on an object are balanced, it won't move. This would apply to a captive balloon, held to the ground by a rope. The upward force of the balloon's buoyancy is balanced by a downward force in the rope, and these must be equal. The same argument for you sitting still in your chair, your weight is balanced by an upward force in the chair.
The force in an inflated balloon is exerted outward equally in all directions.
A balloon powered car is moves because the balloon pushes out air. Whenever something exerts a force on something else (in other words, the balloon is exerting force on the air), then the object being pushed always exerts an equal and opposite reaction force on the object exerting force on it (in other words, the air exerts force on the balloon). Because the balloon is attached to the car, when the balloon is pushed by the air, the car is pushed. The law that for every force there is an equal and opposite reaction force is Newton's Third Law of Motion.
Electrons move between the hair and the balloon.
