(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.
A cool dark cupboard is fine for the short term, since exposure to air and light hastens oilâs rate of oxidative rancidification and the creation of off-flavors and odors. But for long-term storage (beyond one month), the cooler the storage temperature the better. We fried chicken in vegetable oil and then divided the oil (strained first) among three containers and stored them in various locations: in a cool, dark cupboard; in the refrigerator; and in the freezer. Two months later, we sautÃ©ed chunks of white bread in each sample and took a taste.
