(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.
Store the following oils in a cool, dark cupboard. * Refrigerate olive oil if your kitchen is humid and the temperature is 80Â°F or higher on a regular basis. These delicate oils are especially prone to going rancid if theyâre exposed to too much light and heat â refrigerate after opening for maximum freshness.
