Hi Sharon,

I got the following e-mail and I have no clue what this experiment is
all about:

My name is Eric Arnold, I am a senior in high school, and I'm
taking AP physics. We have to do a semester project on anything physics
related. I asked my dad for an idea and he said that when he was a kid he
made a speaker out of a flame. He couldn't remember all the details, but
thought it involved putting a string soaked in salt water in the flame,
and then putting the ends of a speaker wire in the flame. If you know how
to do this, or have an idea of where to look, who to ask, I would greatly
appreciate it.


Have you ever seen/done/heard about the above project? I don't know what
salt water does to string and why the string would not burn at some point.
Thanks
