Can a metal ring and soap solution create expanding bubbles?

AI Thread Summary
A soap bubble can expand when given a charge, but the expansion primarily occurs as the bubble fills with air. The discussion explores whether a metal ring, when wetted with soap solution and blown into, could induce charges that would cause the bubble to expand further. However, it is suggested that the friction between the metal and the bubble is unlikely to generate sufficient charge unless the metal is pre-charged. Ultimately, the main factor for bubble expansion is the air introduced from blowing, rather than any charge induced by the metal ring. The interaction between the metal and the bubble does not significantly affect the bubble's size.

I've heard that, when a soap bubble is given a charge, it expands.
I was just wandering whether, when you wet a ring made of metal with a soap solution and blow to it slowly, the bubble created expands because of theat above principle.
Does The friction between the metal ring and the bubble induce some charges on the bubble and make it expand?

I doubt it, unless the metal was already charged to begin with. The bubble expands as it fills with your breath.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
