It is a liquid at room temp and normal pressure (unlike butane - as others have mentioned). Zippos use a wick and fuel reservoir- like a tiki torch or hurricane lantern - instead of a valve like disposable bic lighters - which are more like a propane torch. Because of the different technology involved - you cannot use butane in a zippo-style lighter. You can use other brands of lighter fluid (Ronsol), Naptha: Jet Fuel, white gas, Coleman fuel, alcohol, kerosene, diesel, etc. with varying levels of success. Getting the butane OUT of a disposable lighter is easy - just hold down the button without striking the flint, pointing it down into some container. It is heavier than air. Getting INTO something else is basically impossible, but cans of butane are cheap an available at smoke shops and hardware stores (I have a butane soldering iron as a refillable butane lighter so always keep it on hand).
