Everyone knows how to refill a Zippo or butane lighter, but what about the Bic disposable lighters? Believe it or not, you can actually refill those, too! All you need is some lighter fluid and patience. Make sure that you do not accidentally crack the lighter while you refill it - you can prevent cracking by letting the fluid enter in short bursts and then letting the gas out. This will normalize the pressure inside the lighter and help prevent cracking and breaking (because no one wants lighter fluid on their hands when they're trying to light a lighter).
