Soap Film Formation: Explaining the Phenomenon

[andyrk]

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?

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think that a layer of soap molecules exist on the water surface and while the wire ring is dipped into the water and withdrawn, some of that layer sticks to the wire.
