Sounds

Sounds are caused by Vibrations
I hit the jars with an unsharpened pencil  the less water there is the sound is lower.  I even played mary had a little lamb, the sound was not perfect but you could make it out.   Put your fingers to your neck and hum, did you feel the vibrations, those vibrations is what creates the sound.  Neat huh!
