Product Details

Are volatile, flammable liquid vapors heavier than air? Safely demonstrate to students that using flammable liquids indoors can create a fire hazard—even if you are quite far from an open flame. In this impressive demonstration, hexane vapors are poured down an aluminum vapor ramp toward a lit candle. When the vapor reaches the flame, all three necessary ingredients for a fire are present—oxygen, hexane fuel and a source of ignition. The flame travels back up the ramp leaving an impressive trail of fire as it goes. A very safe demonstration illustrating organic vapor flammability.

Concepts: Combustion, flammable liquids, fire safety.
Time Required: 15 minutes

Performance Expectations

MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS4-2: Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
HS-PS4-4: Evaluate the validity and reliability of claims in published materials of the effects that different frequencies of electromagnetic radiation have when absorbed by matter.
