Zinc Pyrotechnics - Chemical Demonstration Kit

By: The Flinn Staff


A spectacular “fireworks” display is initiated by adding two drops of water to a mixture of dry chemicals. Place a beaker with very small amounts of zinc dust, ammonium nitrate, and a catalyst in a fume hood. Add two drops of water to the mixture and watch as sparks, smoke, and excitement fill the air. Must be performed on a heat-resistant surface in a fume hood or outdoors.

Concepts: Exothermic reactions, catalysts.
Time Required: 15 minutes
Chemicals Provided: Zinc dust, ammonium nitrate, ammonium chloride.
