Soap Film formation

  1. Aug 28, 2013 #1
    When we dip a wire ring in a soap solution and then take it out, why does it form a soap film inside? Is there any explanation behind it?

    Do you disagree with Wikipedia?

    there is explanation for everything :)

    the phenomenon concerns structure of soap molecules, their interaction with water and with the wire, adhesion and cohesion, surface tension... You need to read about them.

    You see a lot of things here http://www.funsci.com/fun3_en/exper2/exper2.htm
    At first, you can think that a layer of soap molecules exist on the water surface and while the wire ring is dipped into the water and withdrawn, some of that layer sticks to the wire.
