Surface tension

This is rubbish. Bubble do not break the surface tension, bubbles are
little balls of surface tension. It sounds like someone has taken a quite
long explanation of why the gaseous exchange takes place, and simplified
it to the point where it is no longer true. The truth is all about rates
of delusion and fluid dynamics, which are far too complicated to go into
here - and anyway I'd have to go and look them up.

Thank you Roger, I suspected that was the case.
