Diesel engines were created based off a scientific law known as compression ignition.  Rapid compression of a gas will increase its pressure and temperature at the same time. If the compression is done quickly enough, the temperature of the gas can become several times that of its surroundings, becoming hot enough to ignite tinder or other flammable substances.  This fire syringe shows how this principle works.  Simply put a small piece of cotton into the tube using the hole on the tube's cover. Then quickly press down on the handle to suddenly compress the air in the tube. When applied properly, the cotton will begin to burn. The air in the cylinder will act both a source of heat and as an oxidizer for the cotton when properly compressed.  Comes complete with spare O Rings and cotton.  A great experiment to use for any chemistry class!

Size of syringe is approximately 11.5 inches long when handle is fully extended.

5 star rating  Wonderful!
da Silva from Rio de Janeiro
This Fire Piston is very good. My students were befuddled with their achievement. Great tool for my school work.

3 star rating  A good pressure to heat energy transformation demo
Mike from Sandia Park, NM
The fire syringe works well when it is clean and a bright light is shining through the device as it is being operated. The amount of force needed is fairly high, some 5th grade students cannot exert enough force. Is also impressive in a totally dark room, if it is clean. Cleaning the narrow bore can be tricky.
