Observing
When taking notes of the soft drinks you might want to get the pennies out for some seconds so you may have a better look at them. When looking at them you might want to ask yourself, Is one type of soda visible reducing the amount of tarnish present on the penny?, Do the lighter sodas take the tarnished off faster than than the darker sodas?, Do the lighter sodas take off the tarnished faster than the darker sodas or do the darker sodas take off the tarnished faster than the lighter sodas?, Do the lighter sodas change color as the tarnished is removed?, How does this compare to how much tarnished is on he penny that is soaking in the distilled water?
