Any watches that I wear start to corrode. I got a new Timex for Christmas and the side that faces my hand is already rotting(little holes, rough spots from pitted metal). My dad has a Seiko and his is okay. Whenever I wear new rings(anything except gold or platinum) they start to corrode and pit. Sometimes they even turn black on the inside and anywhere they touch my skin. Same thing for my dad.
Occasionally they'll even turn my fingers green(my husband and I bought matching engraved rings at Disney; mine turned black and my finger green and his was fine).
All my earrings have to be for sensitive ears or they get infected and the holes get black around the edges.
Anyone know why this happens or what causes it? Anything I can do to save myself from having to buy new watches ever 6 months - a year?

I know that cars can run on 85% ethanol and 15% petroleum, but what is it that ethanol lacks that makes it impossible for them to run only on ethanol?
What are some sources of ethanol, other than corn?

When ever you mix Diet Coke with any amount of Mentos, it makes the soda sort of explode. Why does this reaction happen?

we were taught in high school that when a burning matchstick brought close to oxygen it burns more brightly.
so why dont we add oxygen to cooking gas so that we get more out of the gas?
