Aron's Travails

Ive got the batteries, I’ve got the water, I’ve got the modle type writen down so i can get the same solar cell. My laser pointer has a max output of 4mW@630-660 nm. Is this the same strength as yours? I assume all red comsumer laser diodes are pretty standard? I got some silver wire. Its pretty thick. Does this sound like the right stuff. The package says Stearling Silver Garanteed? Is there a way I can tell, maybe by the reaction in the water? How might one test this?
