I have a lovely bottle of soapy liquid and enjoy blowing bubbles. When i blow the bubble is it still a liquid?

Liquid and gas. The bubble layer is liquid, the air inside is gas...

hmmm i wud think that it is a liquid with its surface layer not broken (water has  surface layer i will try to find a site explaining it) but anyway it it just surface layer of water and once that breaks it it done

A bubble is held together by surface tension. The soap is a surfactant and when I grow up - say I'm 80 years old - I will understand all of the math behind bubbles. As a surfactant soap lowers the surface tension of the water. How this allows bubbles to form I can't figure out even with all of the math given for me. It allows for formation by letting the water spread out more but from that point on, trying to understand the thermodynamics of a bubble, I'm lost.

The link to it is:
