OK, I may be being stupid here; what difference does the rain make?

With a cylinder of compressed gas, you can, but I suspect you might have a bit of trouble doing it simply under your own breath (go 6 foot under water, exhale into the balloon, then try taking a deep breath for the next breath into the balloon - could present a problem - maybe overcome with scuba gear, but still problematic).

The other problem is that under water, you have to contend with greater pressure, so you will have more work to expand the balloon to a given size.

Finally, as the balloon fills with gas, it will gets steadily more buoyant, and you will have to expend ever more effort keeping it beneath the water.

"i wasn't going to go swimming in the rain."

Were you concerned that you might have got wet?

I don't think he meant to be rude (the hint of sarcasm I think was meant more jovially than out of rudeness).

The point is that you said nothing about thunderstorms, and over here, only a small percentage of rain is associated with thunderstorms, so it would not be natural for us to automatically think that when someone talks about rain that they are thinking about thunderstorms.

Sorry, I meant no offense.
As another-someone said I don't usually think of rain as more than annoying. Also, most of the pools I have seen have been indoors ( the weather here isn't usually good for swimming) so the idea of worrying about the weather seemed odd. I thought that you were joking about the weather making a difference.
