Cbulla,
I don't recommend an air horn. When I was a teenager we had those little can air horns for alerting in case of emergency. Being teenagers we grabbed one and hoped in the pool with it, to see what it sounded like under water. It made noise, but whatever is in that can froze in the airhorn part and the thing free flowed until it was empty, it had a good size block of ice on it by the time it finally stopped. And that was in an 80 degree pool.
