I am doing a science fair project making 7 tin can telephones 
and using 7 different materials for the "string".  I am using 
kite string, twine, wire, plastic, fishing line, and rat tail.  I 
am doing research on how sound is made, but the teacher wants 
some research also on how these different materials transmit or 
conduct? sound.  Can you help me?
