If you are as unfamiliar with Boyle's Law as I was, it essentially dictates that compressed air in a small container can increase temperature to the point of combustion; this is the law that the Fire Piston abides by. Forget fuel, wood or whatever else you would traditionally make a fire with, conjuring it out of thin air is much cooler.

This particular Fire Piston may seem expensive at $50, but it will never have to be replaced nor refueled. Equipped with an aluminum rod and encased in acrylic glass, this version is made for science demonstrations.
