The Flaming Vapor Ramp Chemical Safety Demonstration Kit safely shows students that using flammable liquids indoors can create a fire hazard—even if you are far from an open flame. This safe display illustrates organic vapor flammability.
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 Materials Provided: Hexanes, vapor ramp, candle.
