Code Number: 4A40.70
Demo Title: Liquid Oxygen - Acceleration of Combustion
Condition: Excellent
Principle: Accelerating Combustion
Area of Study: Thermodynamics
Equipment:
Petri dish, Liquid Oxygen, Dewar, Tongs, Grill Lighter, Animal Crackers, Cigarettes, Rice Krispies.
Procedure:
NOTE: This equipment is also used for the 4C30.80 and 5G30.20 demonstrations.
Prepare some liquid oxygen using the copper LOX generator. Soak the animal cracker or cigarette in the LOX for a period of time. Place the cracker in a Petri dish and light with the grill lighter. The cracker should be consumed in a few seconds because of the greatly enhanced presence of oxygen.
