Can a metal ring and soap solution create expanding bubbles?

Click For Summary
SUMMARY

The discussion centers on the phenomenon of soap bubbles expanding when charged. It specifically examines whether a metal ring, when wetted with a soap solution and blown into, can create an expanding bubble due to induced charges from friction. Participants conclude that the expansion of the bubble is primarily due to the breath filling it, rather than any charge induced by the metal ring. The consensus is that unless the metal ring is pre-charged, it does not contribute to the bubble's expansion.

PREREQUISITES
  • Understanding of soap bubble physics

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.
