I sanded away a bit of the anodizing of an old 486 hsf and dropped it in... and a lil coil of copper wire I had around here.
Right now there is no visible effect to either metal (except for the bubbles on the aluminium, which aren't rising to the surface like yours were) but the water has started to turn an odd brown color instead of the pink WW color (?!?). I think the jar I used might have been dirty before.
