Have a conch shell lying around and an hour to spare? Here's how to turn your shell into a fun and functional horn. (And, yes "conk" is a correct pronunciation. Here in southern Florida, it's pretty much all you'll hear. As in "The Conch Republic," aka: Key West.)

Shot with a tripodmounted Fujifilm Finepix HS10. The continuous autofocus setting performed very well, as did the builtin mic. (Unfortunately, it had no problem picking up the sound of a noisy truck from half a block away.)

Note: Thanks to Better Name Chosen of pointing out my lack of mastery of the metric system. Ignore the metric reference and stick with the awkward Imperial measurement.
