Field Recordings & Bells

In class on Thursday I for some reason felt compelled to try and produce sounds for the river character only using synthesized sound. In recently contemplating more heavily our soundwalk and the direction our group seems to be going in, I realized that at least for the first part of the procession, using some field recordings of natural sounds, processed or unprocessed, might make more sense compositionally. These sounds would not necessarily exclusively be of or from the river, although river sounds will hopefully be utilized.

In terms of non-river sounds, my group has been exploring the possibility of recording bells in water. Bells for sale on craigslist are upwards of $700. Does anyone have any small brass bells at their disposal, or any metal things for that matter, that they are ok with submerging underwater?
