.......and in reply I say!:
So what *is* the pressure in a typical rubber party balloon. IIRC, it gets
*lower* as the balloon expands. I think it's the same with soap bubbles.
It will go past a maximum point, because as the balloon stretches, it
becomes weaker and therefore requires less PSI to expand, but inside
will always be higher than outside pressure.
