(AP) -- Phil DeVore pulls a folded piece of aluminum from a murky pond. The aluminum looks like a piece of siding that's blown off a building, but DeVore knows it's much more valuable than that. He slips a rubber band off the aluminum and unfolds it. He likes what he sees -- 50 or 60 glistening black leeches. They're your common ribbon leeches, Nephelopsis obscura to aquatic biologists.
Storing Used Oil. Used oil can be successfully stored in a cool, dark place for up to a month. Refrigeration or freezing increases the oilâs lifespan by several months. The oil may become cloudy during storage but this is not harmful and the oil will become clear upon reheating.
Reusing Cooking Oil. 1  1. Freeze your cooking oil. After you have put your cooking oil into a container, you can freeze it. 2  2. Reuse the cooking oil for another meal. Oil can be used for frying several times over, as long as you filter it between uses (which means straining it to get all the little bits of food out, among other things.)
