Experiment Cu: vinegar, vinegar + salt, solvent

[Thrilla]

So yea... I forgot about the experiment and they were left outside:
Translucent blue being Vinegar + Salt, transparent blue being Vinegar, clear being solvent paint thinner. (I got rid of the yellow lighting in solvent one in my sig, liquid itself is crystal clear, also the bubbles in solvent were oils dropped in there by accident, it had no effect on the copper what so ever since they didnt touch, and solvent is lighter than oil anyway.)
