A balloon filled with air can demonstrate Newton’s 3rd law of motion.

• The balloon will keep going till acted on by an outside force.

• The reaction is when air comes out of a balloon and the action is when the balloon goes forward.

• The balloon will stay still till acted on by an outside force.

• The action is when air comes out of a balloon and the reaction is when the balloon goes forward.
