A fire piston is an ancient device used to create embers for starting a fire. It’s usually made out of wood or metal, though in the distant past people even made them from bones. The principle behind it is adiabatic heating, where air is compressed so much and so quickly that it heats up to over 800 degrees, igniting the kindling (usually something that lights easily, like char cloth). What’s great about a fire piston is it’s essentially a lighter that never runs out of fuel and doesn’t easily break.
