Compression Ignitor (Pneumatic)

Designed to provide a safe demonstration of generation of heat by gas under compression. Cotton at the bottom of the tube ignites in a flash as the plunger rapidly compresses the gas in side the tube. Also known as a fire syringe/piston. The piston inside a heavy-walled combustion tube is housed inside a transparent plastic outer cylinder which provides an unobstructed view of the action inside the tube.
