This "fire syringe" (or diesel piston demonstrator device) shows the relationship between gas pressure and temperature – and how they can be used to light a small piece of cotton or tinder on fire!
The piston apparatus consists of a thick, clear plastic tube and a plunger. When the plunger is pushed down with a firm grip, the air in the tube is compressed; this rapid compression of the air (specifically called adiabatic compression) elevates the temperature of the gas enough to ignite the cotton fibers of a cotton ball!
Includes instructions on how to use the fire syringe demonstrator.
