Formation of soap bubbles

  1. Feb 7, 2013 #1
    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.
