Action and Reaction!

Can anybody prove me that according to newton's third law,every action has equal and opposte reaction. SO why when we push a box it moves ? Why when we squeez a ballon , it becomes small?

Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Each of these follow Newtons Law, maybe reading how it works better, would give you the answer you wanted.

see, in the case of the box, we are applying force in the same direction and also the force source is in contact with the box. Also, when we squeeze a ball, we are applying force in both the directions. so, it shrinks. But, in action-reaction pair, such as a gun, the bullet moves away immediately from the gun and it will have a recoil force. In a rocket also, we are pushing gases in the opposite direction. We are not pushing that in the same direction. Also read my new discussion, action-reaction forces as a cause of inertia

I think it might have to do something with the fundamental electromagnetic forces, when you push an object, the particles in your hand and the particles in the object are repelling one another, only just at a very short distance. I might be wrong though, this is just an idea.

because action and reaction acts on different bodies.
