Bacteria and oils from being handled by people. Tarnish on the copper part of the penny.
I'm having the same problem! I can't figure out what it is, but, there are droppings that look like mice droppings around the house.
Pennies don't rust. Rust technically speaking is iron oxide and pennies have little to no iron. They do however oxidize, tuning them green from the copper which makes up most of the metal they are made from.
The main change is that the oatmeal will get wet.
because it gets really cold and then it freezes into ice.
because the more southern states are closer to the equator, and the closer to the equator you get, the warmer it gets. it gets warmer near the equator because the earth's tilt has the sun's light/heat fall onto one place (the equator). the earth's tilt also gives us seasons.
DIRT
possible
-- Drop 20 pennies or little stones onto a small patch of bare ground. -- Drop 40 more pennies or little stones onto the same place. Do it carefully, so that you don't scatter them. -- Pick up all of the pennies or little stones and count them. The number you have is the sum of 20 and 40.
when you do not wash your face often or even when enough dirt gets onto your face , the "cleaning" cells cant work as fast so dirt and oil build up blokcing your pores, witch leads to your skin to make the "bubbles" or pimples or breack outs on your face. Hope that helped. Hannah R.
It's called a dirt bath. They dig until the dirt is very fine and then flip it onto themselves until it gets under their feathers. The very fine dirt smothers any lice or mites the birds might have. Dirt is also very good to clean with as well to absorb excess oil. Desert Birds generally do this because of the scarcity of water. Matter fact it works with human hair as well, just might not smell as good as soap :P
Beacause heaps of people have used it before you and also when they buy vegetables the dirt could wipe onto the basket, or when you buy a cold product from the freezer section and it defrosts, the water drips onto the basket. Because no one dries the basket, it gets dirty and mouldy.
DNA gets transfered onto it.
It gets wet!

With a paint brush
you get cross infection through bacteria that gets onto your food
Fire grows when oxygen (air) gets blown onto it.
