Frey Scientific Fire Syringe safely demonstrates that heat is one result of compression in a closed gaseous system. A wisp of cotton is ignited when the plunger is pushed firmly into the shielded cylinder. Heavy walled combustion tube placed inside a transparent plastic cylinder offers a safe, clear view of the demonstration. Cotton and 2 extra butadiene-acrylonitrile rubber O-rings are included. Teacher's Guide and reproducible Student Handout make step-by-step experimentation and analysis fun and easy!
  • Fire syringe offers an explosively fun way to learn about adiabatic compression (rapid compression that raises air temperature) in diesel engines, Ideal Gas laws, the laws of thermodynamics, and more
  • Compression ignition is demonstrated by placing a small piece of cotton at the bottom of the fire syringe and then plunging the piston forcefully into the cylinder
  • Cotton will burst into flame after push-down due to rapid rise in temperature and sudden reduction in volume
  • Included Teacher Guide and reproducible Student Worksheets offer step-by-step guide through experimentation and educational learning
  • Heat science kit comes complete with fire piston, cotton, and 2 extra butadiene-acrylonitrile rubber O-rings for repeated explosive fun in classes, summer camps, and more
