Ballon touch/Float style game

In the game float, whenever you touch a balloon it applies a linear impulse or force, for example, if i touch the top  of the balloon it goes down or if you touch the bottom it goes up and vice versa with everything else, making being able to be moved around freely. i am having trouble recreating this  were as 

applyLinearImpulse()  

 limits you to applying a force in at certain x and y coordinates. please help me on this, thanks!. 

To apply force in the opposite direction just use the same x/y value, but the negative form (i.e. -x or -y)

that helps a bit but its not quiet what im looking for , but thanks anyway. if you could show me a example in code that would be great :slight_smile:

and if you don’t quiet know what im talking about, download it off the app store here.
