Fire Piston

Description:  Fire pistons have been used for hundreds of years as a fire starter. Tinder is place in a seal tube and a piston is rapidly pushed into the tube. The air is compressed increasing the pressure and temperature until the ignition point of the tinder is reached. A diesel engine works in a similar fashion. This phenomenon can be used to introduce the particle model of air and temperature as a measure of the kinetic energy of particles.
