    youll have to find the magnitude between the first touch and the second touch to determine the distance,and have that constrained to a attirubte. Then have all your zoom based off that attirubres. If the magnitude attribute is to small for you to work with then you can multiply it.

    Never actually tried this myself, gonna have to play around with this later
