Bill,

Excellent! Thank you for the follow-up. Using ice tea was brilliant! It makes sense that current is more important than voltage.

<Professor mode> Current measures the number of electrons passing through a system while voltage measure the force at which they are moving (roughly speaking). The more electrons you pump into the salt water the more oxidative products you will form, making it better at killing the wee lil' beasties. </Professor mode>
