@cjrc97, that was a very solid, thorough analysis of the subject of seashell sounds. You're conclusion, though, is spot-on regarding kids' choices. I think it's far more fun and a better story to think that somehow you can find seashells that have somehow, magically, captured the sound of the see. The thing that really helps to further the myth is that instead of just some weird sounds being heard, it sounds like what it comes from.
Very well done.
Nothing wrong with a bit of creative license.
I love my Creative License, it has my picture and everything, lol. Now I wish there were such a thing... maybe I'll have to make it.
