What does a fire piston do? A fire piston is an amazing fire starting device that seemingly produces fire from nothing but air! The secret is that the specially designed piston is rammed quickly into a sealed cylinder with a single stroke. The compression of the air causes the temperature to rise rapidly to 260 degrees Celsius, or 500 degrees Fahrenheit. This is hot enough for the tinder on the piston face to ignite. It can then be withdrawn and transferred to a larger mass of kindling to create a fire. Check out Wikipedia for more.
