Lighting with a zippo

Keep in mind that Bic lighters use isobutane rather than butane. Isobutane has a lower vaporization temperature, which means that it will light reliably down to I think 12 degrees Fahrenheit. Normal butane will lose enough pressure that it won't burn under about 32 degrees Fahrenheit.

Good to know. This explains why my Bics keep lighting on the coldest days, while my torches give up when they get cold. (I generally keep one of each in a dashboard compartment of my car during winter and early spring, but stash the torch in my pants pocket when it warms up -- I've blown a few gaskets leaving them in the car on hot summer days. The Bics' flames barely change with temperature, until they're almost empty.)
