I came into the kitchen after my shower, got a bowl, lined it with foil, poured in some baking soda and some boiling water and dropped in two tarnished sterling silver earrings.
Greg thought this an odd thing to do.
After getting dressed, I came back into the kitchen, removed the earrings from the bowl and rubbed them with a cloth to a nice shine. Then I made myself a bowl of muesli.
My mom told me to try the tin-foil soda thing. There is something about a chemical reaction with the foil, and it works!
