I've tried the mic in a condom underwater trick. I had very limited
success. There was some deal on where they were
selling 6 mics (sm58 rip-offs) for $100. I purchased them, wrapped
them in condoms and tried to seal the end as best as I could and then
threw them off of a dock into the Potomac River. I was attempting to
get water movement sounds, not sea life in particular.

I found that the condoms created a very high frequency clicking as the
mic was getting moved around in the current. It sounds like someone
snapping a rubber glove. These mics also had a real problem with
handling noise-- there was a terrible resonance created by the housing
itself. So I took the mic element out of it's housing, and wrapped a
condom around the element only. I still got the smacking of the condom

I also tried covering the mic element in foam and then wrapping it
with a condom. I had the most luck with this method, but I still
wouldn't call the experiment a success. In my case at least, it seemed
I was recording a condom being affected by an environment rather than
the environment itself.
